This is exact same patch that Digium support tried before sending me new 
fxo modules. That wctdm.c patch did not help in my case.
Interesting, thanks Andrei. I have run for a month so far, without any 
trouble since including this. The issues I have seen, have occured at 2 
week to 2 month intervals.

The system has not had much use for the last 3 weeks, so I'll need to 
wait a few months to be sure.

Then in six months or a year, or whatever timeframe (these things are 
expected to provide many years of use by those who consider their price 
expensive) they will ask you, How do I use one of these newfangled 
ITSPs with our system?

Why do I have to still have to use an answering machine?
Why am I paying $7/line for CallerID?
Can I set this thing up to automatically forward to my cell phone when 
I'm not in the office?

Can we have an autoattendant like everyone else does now?
Why do I still have to pay for conferencing?
Can I set things up so that all the sales phones ring at the same time 
until someone picks one up?

Etc. etc.
I fielded questions like these from a businessman the other day who 
loudly bemoaned having invested some fairly hefty cash (in small 
business terms) on a Nortel key system, THREE YEARS AGO.

Imagine what he would have sounded like had he cut that check last month 
instead.

Maybe these talkswitches are smart and can do a lot of those things.  I 
don't know anything about them.  I do think the play that VoIP is

Analog line for business is about $50 plus tax with unlimited LD and all

Also there are middleman companies who buy wholesale from Verizon and

$37 sounds cheap even for residential lines. As for BRI costing more,
don't forget for every BRI line, you get 2 bearers or the equivalent of
2 analog phone lines. 

BTW, the metered time on a BRI is not a verizon thing but rather your
local PSC or equiv was buffaloed into giving it up for the telco. The
PSC here was pretty reasonable before it was disbanded.

Here we still get business rate BRI is $90 a month after all taxes and
is unmetered for local calls.

Again, if the TDM400P is drawing more than a couple hundred milliamps over

your PSU can't source a couple hundred milliamps more than it is under normal 
load, you've specc'd it too close to your average draw.

 nominal when ringing all four lines, something is wrong in the design, and
 if your PSU can't source a couple hundred milliamps more than it is under
 normal load, you've specc'd it too close to your average draw.

If your motherboard requires 5amps when your psu can only supply 4, then
you're going to have trouble.

This IS a problem, just that it may not be in your case.

RE: [Asterisk-Users] Qs about FXO/FXS cards

2005-01-03 Thread Rich Adamson
 I have been wondering if the spa 3000 would make a good PSTN interface
 for an * box where POTS is the only available (or practical) service.
 Have you implemented this? Are there any limitations or known issues?
 The SPA2000 sure seems to work well as an ATA, even had good luck with
 fax over IP using g.711 and the fax detection in zaptel and the SPA
 (turns off echo cancel dynamically when the CNG tone is heard I
 believe).
 
 Can you use the FXS and FXO ports at the same time, for two separate
 calls via * ?

Yes, it works fine.
 
 The SPA 3000 is small enough that a half dozen of them would be
 manageable, any more than that and your are usually in the T1 price
 range for service anyways.

The down-side to the spa3k is that its rather difficult to configure 
since they've provided so many different config options and their user
manual does not address much beyond a basic config.

For my home use, I inserted the spa3k into the pstn line in such a way
as to avoid remedial spousal training. :) All house phones are attached
to the fxs (line 1) port.

This specific config supports:
- all outgoing fxs - pstn calls are passed through to the fxo port
  without asterisk being involved. (eg, avoids 911 and training issues)
- all outgoing fxs calls prefixed with a 8 are routed to * for
  completion (regardless of what follows the 8).
- all outgoing fxs calls matching 3xxx (* extensions) are routed to
  * for completion.
- the fxs port was configured to register with *, and therefore the fxs
  port is also an exten from asterisk's perspective (eg, * exten's can
  dial the fxs port)
- distinctive ringing is implemented as:
   - incoming pstn calls (via fxo port) ring normal
   - incoming voip  * calls use a distinctive ring
- the fxo port was configured to register with * (different creditials
  from the fxs port), and therefore asterisk can place calls through
  the spa3k fxo port.
- I specifically did _not_ want * involved with incoming pstn (fxo)
  calls (in this case), but rather wanted those to ring through to the
  fxs port directly. (Avoids complaints when care and feeding *)
- the spa3k is running v2.0.11(GWg)

The only difference between the above and using the spa3k as an inbound
pstn gw is the definitions for the pstn (fxo) port. If you dig through 
the voxilla.com forum postings, you'll see where that also has been
implemented. However, that fxo - * connection is even less clear. I had
that working several months ago, but that wasn't my specific objective
so I didn't attempt to document it.

The problem with most of these external gateways (regardless of vendor)
is that it almost requires a knowledgable person with a packet sniffer
and a lot of trial  error mucking around to find the appropriate
combination of parameters to accomplish a specific task. In my specific
implementation above, the key turned out to be extensive use of dialplan
strings that were not very well documented.

While this has stemmed from my semi-educated guess, I would be most
concerned with current instead of voltage. When I previously abused a PC
PSU it was driving a high torque 12v electric motor. The really high
torque motors would peak out at 5 amps during spool up. That would cause
a PC PSU to pulse between something like .5 amps and 4 amps. If the
spool up was controlled, I could keep the motor under 4 amps and the PSU
could drive the motor. I had no interest in the voltage because it was
the current that ran the motor.

  That is a simple find, a better one would be find / -ls, you should

 yes it's a simple find but there would be significant disk/cache thrashing

Okay, link this to my rambling above and you would see that by thrashing
the disk, you are actually keeping the spindle spooled up and not
measuring the spool up draw. My guess is a spooled down machine getting
a random incoming call that then must generate ring and spool up the
HD(s) to start writing logs at the same time on a questionable PSU.

As far as I know, with the exception of a couple of video cards that
resorted to an external PSU, all video cards have to draw from the PCI
or AGP bus. This means the TDM card is likely to draw more than the
graphics card.  Heavy HDD thrashing uses less power than the spooling up
of an idle drive. 

I'm also starting to wonder about specific phones now as well. While
this next bit of rambling is not asterisk related, it is phone related
and something to consider. While out at my mothers house, she had a
phone next to her PC that wouldn't ring and when used would cause the
DSL to drop out. I happened to buy a new cordless phone for her and
replaced a phone that was working elsewhere in her home. After putting
the new cordless phone in, the phone by her PC started ringing properly
and was able to be used without dropping the DSL.

You guys probably don't know what Digium did recently to address TDM400  
problem:
- they've sent new FXO modules to all customers who were complaining 
about TDM/FXO issues.
What I've heard from a Didigum reseller/supplier it might be a situation 
with specific telco lines here in US.

The new FXO modules SOLVED my problem. I have stable Asterisk system in 
production for more than 3 weeks now.
I used to have the recurring problem every day, in about 6-8 hours after 
server reboot / Asterisk restart / modules reload.

I too have struggled with getting reliability out of the common FXO
options. However, we should also keep in mind that BRIs are available,
although not as common as POTS lines in the US. A local CLEC pointed me
to a web site run by the state of Texas that stipulates the tariffs
allowed for PRI and BRI. BRI are actually very cost effective relative
to POTS lines since many bundled options like CID are built in. a BRI
pair is around $57/mo here.

If the TDM400p did not work out for me, which is has to this point,
then switching to a BRI would be my next option. It seems that from
casual monitoring of the list that BRI interfaces are mroe reliable
than FXOs.

Digium makes T1 and E1 interfaces. Take a moment and read what I have

these T1 and E1 interfaces. 

If you truely wanted to know what I use and how much I have installed,
you only need look at the archives. The company I work for has a T1
fully deployed right now and are expecting a second one any week now. We
have extra capacity in hardware reserved for a customer of ours who has
expressed interest in upgrading soon and needs more lines. 

I used to even have a T1 card and channel bank to run my home system
till I grew bored of it and decided it was better to spend my time doing
other things than managing the phones at home. Currently that system
minus the server is with VCCH.com and they use it occasionally for
demonstrations.

 Btw, we are a textbook small office install according to the docs.

And barely over the home use of a truely geeky person. I think you
actually qualify as sub-small office.

 Also what the heck is FC?

And those are the ones I see being serviced by people like nufone and
others who will put a machine in a colo facility and get really cheap
PSTN connections for you and then you don't have but 1 analog port at
most to bother with locally. 

Any small business that is going to balk at a good system is going to
balk at ever spending any money and may be a good candidate to go the
legacy route and learn what a good raping really feels like. If they
don't want to spend money on the infrastructure, you will find that they
probably are too marginal to stay in business very long.

As a contractor, those would probably be the accounts you will regret in
the long run anyways. A company willing to come off of the money to do
something right is the ones who you will make a nice profit margin off
of and not have to haggle over price when repairs are needed.

 Unfortunately that makes Asterisk installs for small businesses more 
 expensive 
 than necessary.  At US$500 for a T100P and US$300ish for a channel bank (FXS 
 only, FXO is significantly more expensive!) plus your time and system for an 
 Asterisk install it raises the bar for the small business to adopt Asterisk. 
  
 The TDM400P would fit a very nice little niche if it worked reliably.
 
 Let's face it -- most businesses are looking at VOIP to reduce their 
 telephone 
 bills and if the time it takes for the install to pay for itself is raised 
 significantly (like an added $1000 price tag for reliable equipment)... 
 well... the writing on the wall is pretty clear.
 
 I too have struggled with getting reliability out of the common FXO
 options. However, we should also keep in mind that BRIs are available,
 although not as common as POTS lines in the US. A local CLEC pointed me
 to a web site run by the state of Texas that stipulates the tariffs
 allowed for PRI and BRI. BRI are actually very cost effective relative
 to POTS lines since many bundled options like CID are built in. a BRI
 pair is around $57/mo here.
 
 If the TDM400p did not work out for me, which is has to this point,
 then switching to a BRI would be my next option. It seems that from
 casual monitoring of the list that BRI interfaces are mroe reliable
 than FXOs.

For business use, I would suggest you first find a BRI card you can use
here in the states. Hint, bug Kapejod into making that 4 port card US
ready. Then move any business user over to BRI if they want small
deployments. The 8 lines you can get by one 4 span board from Kapejod
would be wonderful for a small business and it gives you answer and
disconnect supervision. It will give you a lot of other benefits that
analog can't. 

That also would go a ways to making a more reliable from the wires
standpoint system as well. I doubt you will have as many unexplained
problems from a BRI circuit.

Lousy cordless phones, and some plain phone produce lousy voice quality
when the power circuit is used for anything else (especially fluorescent
lights).

Maybe this is relevant?

Using your DSL line for phones without proper filters is noisy too.

   No you didn't. What was the power load when the modules failed?
 
  The actual current draw I did not measure -- I was looking for
voltage
 sags or
  swells on the +5V and +12V lines during load.
 
 While this has stemmed from my semi-educated guess, I would be most
 concerned with current instead of voltage. When I previously abused a
PC
 PSU it was driving a high torque 12v electric motor. The really high
 torque motors would peak out at 5 amps during spool up. That would
cause
 a PC PSU to pulse between something like .5 amps and 4 amps. If the
 spool up was controlled, I could keep the motor under 4 amps and the
PSU
 could drive the motor. I had no interest in the voltage because it was
 the current that ran the motor.
 
   That is a simple find, a better one would be find / -ls, you
 should
   also try running seti on all processors at the same time.
 
  yes it's a simple find but there would be significant disk/cache
 thrashing
  when combined with a kernel complile, as I'd mentioned.
 
 Okay, link this to my rambling above and you would see that by
thrashing
 the disk, you are actually keeping the spindle spooled up and not
 measuring the spool up draw. My guess is a spooled down machine
getting
 a random incoming call that then must generate ring and spool up the
 HD(s) to start writing logs at the same time on a questionable PSU.
 
   If your motherboard requires 5amps when your psu can only supply
4,
 then
   you're going to have trouble.
 
  Yes I completely agree with you here.
 
   This IS a problem, just that it may not be in your case.
 
  I am willing to bet that my case is the more general case here --
The
 TDM
  current draw just is not a big draw, or at least it should not be --
  certainly no more than a HDD during heavy seeking or a video card
during
 some
  intense gaming sequences or even some of the larger data
acquisition/DSP
  cards I've used in the past.
 
 As far as I know, with the exception of a couple of video cards that
 resorted to an external PSU, all video cards have to draw from the PCI
 or AGP bus. This means the TDM card is likely to draw more than the
 graphics card.  Heavy HDD thrashing uses less power than the spooling
up
 of an idle drive.
 
 I'm also starting to wonder about specific phones now as well. While
 this next bit of rambling is not asterisk related, it is phone related
 and something to consider. While out at my mothers house, she had a
 phone next to her PC that wouldn't ring and when used would cause the
 DSL to drop out. I happened to buy a new cordless phone for her and
 replaced a phone that was working elsewhere in her home. After putting
 the new cordless phone in, the phone by her PC started ringing
properly
 and was able to be used without dropping the DSL.

Why would a system with five analog lines and ten extensions not be
considered serious?

Every major corporation is starting to target the SMB market.

A working solution for this kind of setup is a must.

It can help all of us who want to setup asterisk in small businesses.

Gosh, you sure are full of yourself.

You just shouldn't ASSume that everyone knows all of the abbreviations
and when they ask you needn't be rude.  Being condescending is the first
sign that a consultant is shallow and not worth using.  A *good*
consultant will take the time to explain things and will never bash the
situation that a customer or potential customer is in.

Hardware and technology never become obsolete, they simply become
outgrown.  A customer's given choice in technology is typically made
based on the best available balance of money, commitment, and need.
Making high handed and unqualified statements is a waste of your time
and mine.  T-1's are rather unpleasant to move and for most small
businesses are completely unnecessary, in my opinion.

While you may have the money to burn by having a t-1 at home, most small
business owners would rather use what is necessary as opposed to what is
extravegant.  And as you so nicely put in your other post, customers who
come off the dime are a joy to work with.  And I suspect most of them
wouldn't tinker with * they would go straight to Cisco or Nortel, or a
brand name that works turn key.  

While I'm sure we haven't heard the last of your POTS bashing or small
business bashing I've got a bit of a request/challenge.  Instead of
bashing those of us who run small businesses, try to contribute to the
list by being open, modest, and professional.  Who knows, you might find
a new client, and you never know which small business will grow into
the medium client who has money to drop.  I know I'd sure look
forward to reading your posts if you were contributing useful
information and not just bashing the line mix that works for our
company.  

You see the charm in * for us as a small company is that we can
implement big company features, control costs, make better use of people
and lines which will probably help us avoid needing 8 or 10 lines that
would require a T-1.  Regardless of if you like that, that's a cool and
powerful thing.  That is why * rocks and why there will be more of us
that adopt it that you will want to shake a stick at.  And while * is a
bit of a stretch for a home use, it's a slam dunk for any size business.

And that is just the start.  Granted, programming text files is

RE: [Asterisk-Users] Qs about FXO/FXS cards

2005-01-03 Thread Damon Estep
Brian,

People are making 100's of excuses for *'s inability to deal with analog
lines and extensions, the bottom line is that it is a serious issue that
we all hope to see resolved. The best one is analog lines are for
babies

Bottom line, the economics of analog vs. t1 usually work out so a T1 is
easily justified when you have about 10+ analog lines, that means that
offices with 20 to 30 users are borderline on being able to justify the
expense of a T1.

As best I can tell * can not really handle more than 50 to 100 calls at
a time (on a single box), and then only if there is not a lot of other
stuff (transcoding, vmail, etc.) going on.

This makes * a slam dunk for environments that handle somewhere between
10 and 100 simultaneous calls, and a not so easy decision for users with
less than 10 or more than ~100 simultaneous calls.

The best workarounds at this time for small (analog) implementations is
to use an external VoIP to PSTN gateway or a T1 interface and a used
FXO/FXS channel bank.

For larger installations (more than 2 to 4 t1s) there are other
scalability issues, such as no SIP reinvite, meaning all of the call
data streams must run across the PCI bus of the PC. This can be solved
with a proxy like SIP Express Router aka SER and a media gateway like
the Lucent Max TNT so * is only in the data stream when the features it
provides are needed.

Our range of customers and applications spans from 5 or 6 analog lines
to a DS3 (672 digital lines), and we have quickly determined that the
TDM400 in the majority of hardware combinations we have tried is not
100% reliable. We have tried old Dell PII 500s, New HP Xeon 3.0s, and
everything in between, all quality system boards, power supplies,
dedicated IRQs, hardware raid controllers, high quality NICs, etc.

We have tried machines that can pass real time HDTV video/audio streams
across the PCI bus with bit for bit accuracy (translate: no PCI
latency).

As far as all of the power supply related issues are concerned, it is
not really the job of the power supply to FULLY regulate the power, it
provides GOOD power to the system board and other components which are
then expected to have integral voltage and current regulators suitable
for their application.

It is my understanding that all of the power for an FXO module comes off
of the PCI bus, and only the FXS module requires power straight from the
power supply, yet they both suffer from the same lock up issue, and the
funny part is the driver has no idea the hardware is not responding.
This is clearly a problem with the hardware/driver design. There does
appear to be some combinations that work, but that is not acceptable,
unless the exact requirements can be quantified and advertised.

Find a good PSTN to VoIP gateway and forget the headaches... in time the
TDM400 might improve, but not as a result of the long running rants in
this forum.

Maybe you should read and fully comprehend before starting replies. It

  sign that a consultant is shallow and not worth using.  A *good*
  consultant will take the time to explain things and will never bash
the
  situation that a customer or potential customer is in.
 
 Boy am I glad I am not a consultant and I don't have to deal with them
 very often. And I hope you understand that if all the effort you can
put
 forth is to ask questions with no research behind the question, you
 won't make it very far yourself.
 
  Hardware and technology never become obsolete, they simply become
  outgrown.  A customer's given choice in technology is typically made
  based on the best available balance of money, commitment, and need.
  Making high handed and unqualified statements is a waste of your
time
  and mine.  T-1's are rather unpleasant to move and for most small
  businesses are completely unnecessary, in my opinion.
 
 Funny. Obsolete is when the majority of people determine it would be
 better to be impaled by a red hot poker than use the technology. Well
 actually I think the thresh hold is quite a bit lower. How many
serious
 companies are still using PDP's in production? Know of any one still
 seriously using 8088's on the desktop?
 
 T1's aren't anymore painful to move than several analog lines. Add to
 that that you don't need a T1 to use T1 interfaces as I'll point out
 below.
 
  While you may have the money to burn by having a t-1 at home, most
small
  business owners would rather use what is necessary as opposed to
what is
  extravegant.  And as you so nicely put in your other post, customers
who
  come off the dime are a joy to work with.  And I suspect most of
them
  wouldn't tinker with * they would go straight to Cisco or Nortel, or
a
  brand name that works turn key.
 
 Maybe you should read and fully comprehend before starting replies. It
 is very helpful to do inline posting so you can see what it is your
 responding to. It is possible you might have figured out how much you
 missed if it was closer to what you where writing. Specifically I
stated
 that at home I had a T1 card and a channel bank. There was never a
 mention of a T1 circuit. To finish connecting the dots for you, I did
 VoIP to the office and had 24 extension capability and about 17 actual
 extensions on my system at home.

 You guys probably don't know what Digium did recently to 
 address TDM400
 problem:
 - they've sent new FXO modules to all customers who were 
 complaining about TDM/FXO issues.
 What I've heard from a Didigum reseller/supplier it might be 
 a situation with specific telco lines here in US.
 
 The new FXO modules SOLVED my problem. I have stable Asterisk 
 system in production for more than 3 weeks now.
 I used to have the recurring problem every day, in about 6-8 
 hours after server reboot / Asterisk restart / modules reload.

If we all look back over the archives, we see several postings just
like the two above, and several more that are the direct opposite.

What we don't have from anyone is any form of analysis as to why the
TDM seems to be more sensitive to certain systems then to others. No
one really knows whether the issues are associated with a certain
distro, PIII vs PIV, pci bus support chips, power supplies, ups, etc,
etc. What makes the problem identification tough is the failures tend
to occur at least a week after a reload.

Several people have noted that swapping Mobo from a PIV to a PIII cleaned
up their echo problems, but in all likelihood, the PIII had nothing to
do with it.

Re: [Asterisk-Users] Qs about FXO/FXS cards

2005-01-02 Thread Victor Rini
This has been an interesting discussion. I'll chime in with my 
experience here.

I have two servers. One with the cheapest motherboard and athlon 
processor I could find on Newegg.com. The other is a 1999 era 
motherboard with a Via C3 processor, again a bargain basement special.
The Athlon system has a decent power supply - 400+ watt, the Via has a 
very generic PS that came with the case - 300 watt tops.

On both system I have TDM cards, the Athlon has a 4 port FXS and two 
x100p's, the Via has a 2 port FXS.

Both systems are in production if you could call it that because they 
handle little traffic - home/hobby systems.

I have had no problems at all with the tdm cards or Asterisk. I 
occassionally lose my network on the Athlon machine - I chalk that up to 
the fact that I'm currently sharing an IRQ with two ethernet cards and 
an X100P.

I'm thinking of ditching the two x100p's in my Athlon machine for a TDM 
card with FXO modules to free up a slot and hopefully the burdened IRQ. 
Based on what I'm reading here I probably should think *really hard* 
about that.

If I may, I'd like to ask you some general questions about the
environment these systems are running in.

- How are these systems powered and grounded?
- Are the lines feeding the FXO cards coming from the PSTN, or are they
being fed by a PBX or similar? (basically, how long is the loop between
the card and whatever is feeding it?)

You are successfully running systems that many would tell you to expect
problems with. The TDM400 FXO modules are generally agreed to be an
improvement over the X100P, so if you are having no troubles now, it is
entirely plausible that migrating to TDM400-based FXOs will work for you
as well. Unfortunately, there is no way of guaranteeing that, and it's
your money, so I can't advise you much more than that.

Frankly, what is most interesting is the fact that your systems are
trouble-free. Certainly if you were to ask if such systems could be put
into production, you would probably be advised not to expect much.

There seem to be a lot of variables with these TDM400s.

Cheers,

Jim.

That is the million dollar question. Chipsets and MoBos seem to change
so fast that I've lost confidence in my ability to make sense of it all.
The Intel and ServerWorks chipsets are generally well regarded; Via
chipsets are almost universally avoided for audio work. The
linux-audio-dev folks seem willing to give nVidia's nForce chipsets a
chance. In general, I would avoid PC-class motherboards, and go with
server-class motherboards. That being said, the ultimate goal would be
to find a way to build a reliable Asterisk system on *any* half-decent
motherboard.

Personally, I'm of the mind that power (the power supply, the AC being
supplied to the system, and grounding) plays as much of a role as the
motherboard does, but that is a working theory only. I wonder if clean
power on a lousy MoBo might serve as well as dirty power on a quality
MoBo. If one reads about power quality issues, the symptoms of dirty
power sound suspiciously similar to the kinds of problems people are
having with their analog Asterisk cards.

I'm also wondering about the TDM400s ability to handle PSTN loops at the
extreme limits. Since those TDM cards were probably developed largely in
a lab environment, the telco lines would have been simulated with a
channel bank or C.O. simulator. What happens when the lines fall out of
certain limits? Annenuation, loop current, and longitudinal imbalance
are all factors that proprietary PBXs are able to correct within fairly
wide limits - but they do have limits (a Norstar, for example, tends to
have trouble pulling dial tone when attenuation exceeds 7dB). Has the
TDM400/FXO been similarly optimized? It must have limits; what are they?

I think what we are all looking for is some empirical evidence of what
conditions cause the biggest problems. Is it the TDM400 that is to blame
(either hardware or drivers)? Or is it Linux? PC Hardware? Telco Lines?
Electrical? Grounding? A combination of some or all of those factors? No
one seems to know for certain.

Where much frustration comes from is the fact that a typical PBX simply
does not suffer from these troubles. We've come to expect that our
telecom equipment handles these little noises for us (so much so that
we're suprised to find that these are genuine engineering issues). With
Asterisk, some of the responsibility for correcting those problems falls
to us, the system designers. Unfortunately, a comprehensive engineering
methodology for analog devices on Asterisk does not yet exist. It's all
kind of hit-and-miss.

Re: [Asterisk-Users] Qs about FXO/FXS cards

2005-01-02 Thread Truman Beal
One thing to look at is the proximedy to the powersupply of your audio 
devices.  Some mobos have their chipset integrated in very closely to 
their power supply pins.  With an unclean power source the fluxuations 
would be enough to add some of the white noise which would give you the 
whine.  Excellent examples of that are on the really small all in ones.  
Sometimes power source it self may be in quesiton, and a cheap ups with 
nothing else on it would probably solve that one quickly.  Addionally, 
you may want to see if your power supply offers any sort of shielding.  
Mylar can offer a small amount of shielding, but some power supplys 
won't cool effectively, and the results of that are similar to 
fireworks- (see tom's hardware guide to power supplies)-

Alternatively, you find some cases offer no shielding to the outside 
with their plastic constructs.  A good quality case may be in order, and 
if you are racked, you may want to make sure one of the other machines 
in the rack may not be grounding out onto the rack, thus causing 
additional headaches.

For my setup, I'm not using the onboard stuff in favor of an old sb 
live.  I't moved of to a slot farily away from the digium board , and 
too close for my comfort to the networking cards.  I gain fairly good 
quality, and not enough white noise for me to really pick it up.  In my 
house, there are a few spots where power isn't the cleanest, so I'm 
certain that I'm getting at least some noise, despite every machine is 
fed from their own ups :)

Hope that helps-

I'd stick with the X100Ps for now. Two of my systems where X100s have 
been replaced by TDM FXOs, have seen a drop in reliability - the well 
noted FXO fails to respond to either calls from the PSTN or take calls 
from internal phones. Driver reloads and sometimes machine reboots are 
required to restore operation. These are systems seeing small office 
loads - 30 to 70 calls a day. One of these, which only contained 2 
X100s, ran absolutely trouble free for a year and has required 2 reboots 
since switching to a single 4 FXO TDM.

It is interesting to see there have been no posts to this thread from 
small office load users saying, I am using TDM FXO's and have not had 
any problems at all. All my contact with others in similar situations 
to myself have elicited the same experiences.

Based on the above and following, I'd say the TDM FXO's have issues:
1. The following line in wctdm.c : /* Try to track issues that plague 
slot one FXO's */

2. Digium acknowledge there is a problem and I am currently testing a 
driver modification for them.

Looking at the FXS modules, I too get Power Alarm  messages on a 
semi-regular basis, although they seem harmless. It is hard to see how 
the power supply is involved - short of a PSU suffering very poor 
regulation.

These messages are created by interrupts generated when power 
dissipation in various transistors external to the ProSLIC, exceed 
programmed limits. To quote from the data sheet:

This feature protects the external transistors from fault conditions 
and, combined with the loop voltage and current monitors, allows 
diagnosis of the type of fault condition present on the line.

Anyone interested in learning more, should read page 27 of the Si3210/11 
data sheet, which is available from www.silabs.com, after a free

  This has been an interesting discussion. I'll chime in with my 
  experience here.
  
  I have two servers. One with the cheapest motherboard and athlon 
  processor I could find on Newegg.com. The other is a 1999 era 
  motherboard with a Via C3 processor, again a bargain basement special.
  The Athlon system has a decent power supply - 400+ watt, the Via has a 
  very generic PS that came with the case - 300 watt tops.
  
  On both system I have TDM cards, the Athlon has a 4 port FXS and two 
  x100p's, the Via has a 2 port FXS.
  
  Both systems are in production if you could call it that because they 
  handle little traffic - home/hobby systems.
  
  I have had no problems at all with the tdm cards or Asterisk. I 
  occassionally lose my network on the Athlon machine - I chalk that up to 
  the fact that I'm currently sharing an IRQ with two ethernet cards and 
  an X100P.
  
  I'm thinking of ditching the two x100p's in my Athlon machine for a TDM 
  card with FXO modules to free up a slot and hopefully the burdened IRQ. 
  Based on what I'm reading here I probably should think *really hard* 
  about that.
 
 I'd stick with the X100Ps for now. Two of my systems where X100s have 
 been replaced by TDM FXOs, have seen a drop in reliability - the well 
 noted FXO fails to respond to either calls from the PSTN or take calls 
 from internal phones. Driver reloads and sometimes machine reboots are 
 required to restore operation. These are systems seeing small office 
 loads - 30 to 70 calls a day. One of these, which only contained 2 
 X100s, ran absolutely trouble free for a year and has required 2 reboots 
 since switching to a single 4 FXO TDM.
 
 It is interesting to see there have been no posts to this thread from 
 small office load users saying, I am using TDM FXO's and have not had 
 any problems at all. All my contact with others in similar situations 
 to myself have elicited the same experiences.
 
 Based on the above and following, I'd say the TDM FXO's have issues:

 2. Digium acknowledge there is a problem and I am currently testing a

Have you noticed that a TDM with fxo modules is more/less stable then
a TDM with only fxs modules?

Gut feeling (no reasonable analysis at all) from various postings tend
to suggest the TDM with fxo's is less stable. Would you agree or not?

Also, could you share the driver mod?

If I may, I'd like to ask you some general questions about the
environment these systems are running in.
- How are these systems powered and grounded?
Not optimally by a longshot. On the Athlon machine, my main machine, all 
the equipment is plugged into 2to3 prong adapters. A ground tester shows 
that there is ground but I don't think the outlet is wired for ground - 
it's probably grounded by accident.

The situation on the Via C3 machine is even worse. I have no ground on 
that outlet and no way of wiring it for ground short (no pun) of 
improvising some sort of ground by drilling into concrete or some such 
thing. I've never looked into it - just crossed my fingers and wished 
for the best. This system is my lower use system. I don't get many calls 
on it but I've never had to reboot it because of problems with the 
TDM400 or Asterisk. I dial out on the one phone connected to the system 
occassionally and I usually have availability and when I don't it's 
usually because the network has gone out on the Athlon box - the two 
boxes are iax/ethernet connected.

- Are the lines feeding the FXO cards coming from the PSTN, or are they
being fed by a PBX or similar? (basically, how long is the loop between
the card and whatever is feeding it?)
Yes, the lines come from the pstn. I pulled a run of Cat 5 along the 
outside of the house underneath the overhang of the cedar shingle siding 
for about 20-25 feet from the demarc through a drill hole to the Athlon box.

You are successfully running systems that many would tell you to expect
problems with. The TDM400 FXO modules are generally agreed to be an
improvement over the X100P, so if you are having no troubles now, it is
entirely plausible that migrating to TDM400-based FXOs will work for you
as well. Unfortunately, there is no way of guaranteeing that, and it's
your money, so I can't advise you much more than that.
Frankly, what is most interesting is the fact that your systems are
trouble-free. Certainly if you were to ask if such systems could be put
into production, you would probably be advised not to expect much.
You know what? To top it all off, I also use both systems as routers. On 
the Athlon box, I have three ethernet adapters one of which is a 
via-rhine embedded adapter. I run openvpn, [EMAIL PROTECTED] and a netfilter 
firewall along with Asterisk on that Athlon box. One adapter is 
connected to the cable modem and another to a WAP. The Via C3 system has 
two ethernet cards as well and runs [EMAIL PROTECTED] with Asterisk. Both 
systems are connected with a cheapie powerline/homeplug bridge. My only 
problem with all this is with the network on the Athlon box going down 
once in a great while. An ifdown/ifup is usually what it takes to fix it.

There seem to be a lot of variables with these TDM400s.
Cheers,
Jim.

One last thing. I have a somewhat special PSTN connection. I subscribe 
to comcast digital phone which is dial-tone through the cable tv 
network! Every installation includes an APC unit that is plugged into 
the subcriber's power to maintain dial-tone in case of a power outage 
but I'd also venture that the subscriber's power is tapped to drive 
ringing as well. Isn't that convenient? Instead of the cable company 
paying the electric utility for driving ring voltage you the subscriber 
do that directly.

There seem to be a lot of variables with these TDM400s.

 Those first 3 all sound like you have a problem with power supply and
 consistency. You don't mention what modules you have in the cards, but I
 bet you have FXS ports and have too light of a power supply for the
 job.

Everyone keeps coming back to this light power supply and I just do not buy 
it.  Period.  I'm sorry, Steven, but it's bullshit.  I'm speaking as an 
electronics design engineer and as someone who's been playing with this kind 
of stuff for the better part of a decade.  light power supply is like 
irritable bowel syndrome -- it's what you call the problem when you haven't 
been able to isolate the cause and the patient is demanding to know what's 
wrong with him.

Xeon 2.4GHz system, triple-redundant power supplies, Supermicro server 
motherboard, hot-swap everything.  +5 and +12V lines are within +/- 40mV of 
their target voltages, measured with a 100MHz DSO -- it is *not* a power 
issue.  P3-700 with 12 IDE drives in it, 350 or 450W (but decent make) power 
supply: Power quality is slightly lower but still what I would call 
acceptable.

I get the issue where two of the three FXS modules will be seen.  modprobe 
pauses for a good 5-6 seconds when the third module disappears -- 
unload/reload and it will find it, or not.  unload/reload until it finds all 
three and you're good to go.  

... Except that I can't receive faxes through it.  I can send them just fine 
(there are two different fax machines connected up to 2 of the 3 ports, and 
both exhibit the problem.) Use a T100P+Adit600 FXS channel bank and my fax 
rate (in and out) is 100%.  (this is IAX2 to a PRI connected to another 
system in the same location, btw, so it's not a FOIP issue.)  Unplug the 
T100P+channel bank and swap in TDM430P...  can't receive worth a shit, and 
that's all that's changed.  I'm using app_rxfax right now instead of 
Dial()'ing the fax machine on the TDM port, and my rx rate is 100%.  Weird, 
eh?

Perhaps *some* of the TDM issues are power issues but the more I read and 
experience with them on my own the more unlikely I think it is.  Truth be 
told there isn't a hell of a lot of power required to ring a goddamned phone.  
we're talking 20mA loops here and 85VAC.  There is something more insidious 
at work than just bad power.

 give you the

 Sometimes power source it self may be in quesiton, and a
 cheap ups with
 nothing else on it would probably solve that one quickly. 

I have to warn people about cheap UPS units. They have to be a
*POWER-CONDITIONED* UPS to gain the power quality benefits. Many
*cheap*UPS*units*do*not*clean*up*the*power!* Some even make it worse. If
it doesn't say power conditioned, it isn't; it's nothing more than a
battery back up (you will not like what these cheap UPS units do to your
input power when running on batteries).

For eample, APC Smart-UPS models provide power conditioning. ABC
Back-UPS do NOT. Run a Back-UPS on battery only and check out the
harmonics on the output - ouch! It's AC, but it is NOT a sine wave -
it's a square (some of them deliver a stepped square or
pseudo-sinusoidal waveform). Not clean at all. 

Just remember that power conditioners and UPSs are not the same thing.
You can buy stand-alone power conditioners (PowerVar and OneAC make
these), stand-alone UPSs (many cheaper UPS units are this type), or UPSs
with built in power conditioners (PowerVar, OneAC, and APC).

Know what kind of UPS you are buying. 

If you see them trying to tell you something about any kind of
protection, without actually saying the magic words power
conditioned, you cannot be sure that your UPS is giving you clean
power.

 Addionally,
 you may want to see if your power supply offers any sort of shielding.
 Mylar can offer a small amount of shielding, but some power supplys
 won't cool effectively, and the results of that are similar to
 fireworks- (see tom's hardware guide to power supplies)-

Spend the extra money and get PC Power  Cooling (no, they don't pay me,
they are simply the best - no contest).

 Alternatively, you find some cases offer no shielding to the outside
 with their plastic constructs.  A good quality case may be in
 order, and
 if you are racked, you may want to make sure one of the other machines
 in the rack may not be grounding out onto the rack, thus causing
 additional headaches.

Noise could be getting in from all over, eh?

 For my setup, I'm not using the onboard stuff in favor of an old sb
 live.  

What's the SB live for? Console?

 I't moved of to a slot farily away from the digium board , and
 too close for my comfort to the networking cards.  I gain fairly good
 quality, and not enough white noise for me to really pick it
 up.  In my
 house, there are a few spots where power isn't the cleanest, so I'm
 certain that I'm getting at least some noise, despite every
 machine is
 fed from their own ups :)

[here he goes again . . .] Are they power-conditioned UPSs?



 Hope that helps-

 Personally, I'm of the mind that power (the power supply, the AC

 Would it make more sense to get 3 cheap X100P's and use some kind of ATA

Three x100p's are likely to cause even more issues due to the high level

RE: [Asterisk-Users] Qs about FXO/FXS cards

2005-01-01 Thread Nabeel Jafferali
 Current experience... three spa-3000's are far more stable
 then a TDM card, and you'll get three fxo's plus three fxs's
 for less money.

I have experienced nothing but grief when trying to set up the PSTN part
of the SPA-3000. Everything from crackly audio to fast busies.

Has anybody tried the Clipcomm CG-410 4-port FXO gateway
(http://www.voipsupply.com/product_info.php?products_id=241)?

Re: [Asterisk-Users] Qs about FXO/FXS cards

2005-01-01 Thread Lyle Giese
I personally have seen:

1) power alarms on FXO ports.  It appears that rebooting the server is the
fix for this problem.  I have not seen it enough to give definative answers
to questions about unloading/reloading the kernal modules to clear this
condition.  But my experience is that once a port goes into power alarm,
it's basically dead and ignores incoming calls at that point.

2) Two TDM cards, one worked, one didn't in same motherboard at the same
time.  Seperate and unique and non-shared IRQ's.  Second card had problems
dialing out and choppy voice.  Swapped the two cards on the motherboard
between the exact same slots, both now both work just fine.

Subject: Re: [Asterisk-Users] Qs about FXO/FXS cards

 I am going to be putting together my first * system using FXO/FXS
 interfaces. All the systems I have set up thus far have been pure VoIP

 setups.

 The system I need to set up should have 3 FXO interfaces and 1 FXS
 interface, as well as several SIP phones. I have noticed people
 complaining about Digium's TDM cards - are these isolated incidents or

 are these cards unreliable? I intend to get the TDM400P with the
 necessary FXO/FXS boards - can I expect the installation to be
 somewhat straightforward? Any tips to avoid grief?

I think the best that anyone can estimate at this time is that a problem
exits of some sort and it might be related to a combination of factors,
one of which seems to involve specific motherboard designs. There are
far too many people complaining about the same issues with the TDM card,
several of which opened cases with digium support and got no response.
It should be fairly obvious from the many postings on this list since
that card was announced that something is not right, and at least some
of those systems have digiums T1 cards on the exact same pci bus that
are operating just fine.

If you read through the archives, you'll see a number of people flapping
their jaws using adjectives and adverbs about what they think the issue
happens to be, but the majority (if not all) don't have a TDM card and
apparently wouldn't touch one with a ten foot pole.

What is obvious at this point is:
a. no one on the -user list is going to fix (or even hint with any
   degree of authority) the root-cause
b. don't ever post anything to the -dev list regarding a TDM card as
   that is NOT the forum for digium cards or drivers, c. digium support
is not addressing the issue, and, d. the amount of effort required to
support the TDM card (stop *, restart
   the drivers, start *) in its present condition is far greater then
   what any reasonable non-technical customer will endure.

Since this has been an on-going battle, I'd suggest avoiding the TDM
card totally, or, take the 50-50 risk to see how high you can raise your
frustration level.

 Would it make more sense to get 3 cheap X100P's and use some kind of
 ATA for the FXS? Will obviously save a whole bunch of money, but will
 there be significant added complexity?

Three x100p's are likely to cause even more issues due to the high level
of system interrupts. (Note: digium has removed them from their web
site.)

Current experience... three spa-3000's are far more stable then a TDM
card, and you'll get three fxo's plus three fxs's for less money.

I have four of them in service, in everyday use--one RD, one home, and 
two small office.  None has given us the least problem, ever.

One caveat that might be germane, given the complaints of others on the 
list: mine do station (FXS) functions only.  We use all of them on 
SuperMicro mobos, which allow use of the APIC-style IRQs.

My customers are very happy with them.

Since you asked, and since I'm well into this bottle of Merlot on New

1.  Power alarms.  WTF does that mean?  Wish I had some support docs.
2.  On bootup, Excessive leakage module x, ProSLIC failed Auto 
Configuration.  Again, WTF?  Reboot and it's ok.  But, just a reboot 
after driving 100+ miles to the client site is not a good option.

3.  On bootup, a LED won't light.  When zapata gets to it, it can't find 
the channel.  Usually means a complete power cycle to get it to work.

4.  A TDM card that isn't recognized at all.  DOA.
5.  Impedience matching to eliminate humm?
I'm calling Matt on Monday, and hopefully he'll RMA these cards.
I hope that everyone that has a life is out enjoying the New Year.

RE: [Asterisk-Users] Qs about FXO/FXS cards

2005-01-01 Thread Rich Adamson
One rather common problem (which started the most recent thread on the
subject) is the card simply fails to process pstn-fxo calls. Most seem
to suggest it happens about once per week or two. When it fails, 
reloading the drivers clears the problem (which requires taking
* down to do it). There are no log messages to hint at why.

Another problem is documented in bug #2023 (and 2022), which describes 
voicemails left via a pstn-tdm call are consistently very low volume.

 Those first 3 all sound like you have a problem with power
 supply and consistency. You don't mention what modules you
 have in the cards, but I bet you have FXS ports and have too
 light of a power supply for the job.

Oddly, the maximum power requirements of the TDM400 (fully loaded with 4
FXS modules) is 20W. That'd have to be a pretty weak power supply (or
heavily loaded chassis) to have problems drawing that power. Still, I
agree that the power supply is a suspect. I'd want to know who makes the
power supply, which model it is, and whether that model has a good
reputation. An electrically noisy power supply could cause the kinds of
anomalies described. So could a faulty supply, of course.

More important to my mind is the overall quality of the power feeding
the system. Is a dedicated electrical circuit employed? Isolated,
insulated grounding conductor right back to a separately-derived source?
Power conditioner? So many of the problems people are having with the
TDM cards sound like power-quality issues, one has to wonder. I don't
mean that as a panacea, because the TDM400 troubles seem to go beyond
any one issue. It's merely one thing that might bear looking into.

It'd be nice to see some statistics on not only what percentage of
TDM400 users are having problems, but also what kind of environment
they're in. I'd want to know about the elctrical environment,
manufacturer and model of each system component (power supply and
motherboard especially). I'd also like to get a report from a circuit
analysis performed on the PSTN loop. I realize that much of this would
be impossible to get, but one of the most important steps towards
solving a bug is being able to identify the conditions which cause it.
So far that data is not known, which is a large part of the reason the
problem is not getting fixed - no one knows exactly what is causing the
troubles - we just have symptoms.

What if, for example, the TDM400 issues were a cumulative thing? If you
had over 6dB of attenuation on the PSTN loop, coupled with greater than
5V potential on the neutral-ground of your elecrical receptacle,
compounded by a cheap power supply, exascerbated by a Via-chipset, would
you not be virtually guaranteed some strange behaviour? But if your PSTN
was -3dB, your electrical feed derived from a power conditioner, your
power supply manufactured by PC Power  Cooling, and a ServerWorks
chipset-based MoBo, would your system always be faultless?

With enough data, we could really start to hone in on this animal.

 5.  Impedience matching to eliminate humm?

Have you tried the A prefix trick, which uses Line 1 Call Forwarding
as opposed to PSTN Line Call Forwarding (with the added advantage that
the SPA-3000 does not pick up the SPA-3000 line until after the

RE: [Asterisk-Users] Qs about FXO/FXS cards

2005-01-01 Thread Damon Estep
Rich,

I have been wondering if the spa 3000 would make a good PSTN interface
for an * box where POTS is the only available (or practical) service.
Have you implemented this? Are there any limitations or known issues?
The SPA2000 sure seems to work well as an ATA, even had good luck with
fax over IP using g.711 and the fax detection in zaptel and the SPA
(turns off echo cancel dynamically when the CNG tone is heard I
believe).

Can you use the FXS and FXO ports at the same time, for two separate
calls via * ?

The SPA 3000 is small enough that a half dozen of them would be
manageable, any more than that and your are usually in the T1 price
range for service anyways.

Thanks,

Damon

 Current experience... three spa-3000's are far more stable 
 then a TDM card, and you'll get three fxo's plus three fxs's 
 for less money.

RE: [Asterisk-Users] Qs about FXO/FXS cards

2005-01-01 Thread brian
I hate to ask the obvious

But what's your power quality like?  Is the system on a UPS?

UPS supplied power makes a huge difference in system stability.  I
wouldn't run a server for anything (including testing) without it.

Second, what class of hardware?  You do get what you pay for and
flakiness can often be traced to power issues.

From what I can tell the Digium hardware does some signal processing
magic by relying heavily on system power and cpu power.

The first clue here is the 12v plug to provide dial tone/ring to your
ATAs.

BTW, Ring on a analog phone is typically 90vAC.  Dial tone is @48V.  So
if you put a bunch of analog devices in you are begging for headaches.
I learned those numbers after being shocked.  I don't strip phone wire
with my teeth anymore.  Shame on me for being lazy.

I'm a firm believer in not running production systems on bargain
hardware.  I had nothing but grief out of my desktop class and generic
trash systems.  And yes, Shuttle is generic trash, as is ASUS, and A
Open and a host of other Taiwan Special stuff.  The way you save money
in those systems is by making thinner PCB's which will drive you insane
trying to troubleshoot.  One tweak of your case and you can lose some
contacts.  At any rate, judge a circuit by it's thickness.  Trash is
like paper and flexes.  Quality is thick and will cut you before it
bends.

I'm running older, but solid hardware and not seeing any issues.  I'm
using a Compaq Proliant 1850R Gen1 dual PII 400 with 512MB ram, GB
ethernet, and SATA Hardware RAID.  Cheap, efficient, redundant.  And for
a Debian box, good enough.  Initial testing with TOP shows that one ATA
to VOIP connection costs 4% of CPU to start up and then 2% to carry.
Considering we have 10 handsets and 10 employees with 4 lines and
normally no more then 2 people on the POTS lines I think we're in
good shape.  If you're planning to run a E*trade call center, you may
want more substantial hardware.  If you are planning the MomPop
Voicematrix @Home you may be just fine with a old Proliant.  They have
redundant power supplies and they are cheap and indestructible.
Although it's a bit loud to keep in the bedroom.  :)

Don't get me wrong, I'm not trashing your hardware.  If you can run
cheap bargain hardware and get it to work great.  But my experience has
been that I lost my A** on generic knockoff stuff when I sold PC's for a
living.  I spent a lot of time chasing errors that I never could find
the cause of.  Granted my webservers run Windows... And this is a linux
app... But I see uptime in the range of months with Proliant hardware.
That *is* remarkable for MSFT products.  

Anyhow that's my two cents. I wonder if there is a correlation
between hardware class and issues with TDM boards?

Since you asked, and since I'm well into this bottle of Merlot on New
Year's day:

1.  Power alarms.  WTF does that mean?  Wish I had some support docs.

2.  On bootup, Excessive leakage module x, ProSLIC failed Auto
Configuration.  Again, WTF?  Reboot and it's ok.  But, just a reboot
after driving 100+ miles to the client site is not a good option.

3.  On bootup, a LED won't light.  When zapata gets to it, it can't find
the channel.  Usually means a complete power cycle to get it to work.

4.  A TDM card that isn't recognized at all.  DOA.

5.  Impedience matching to eliminate humm?

I'm calling Matt on Monday, and hopefully he'll RMA these cards.

I hope that everyone that has a life is out enjoying the New Year.

Cheers,
Mike

Re: [Asterisk-Users] Qs about FXO/FXS cards

Hello.

I am going to be putting together my first * system using FXO/FXS
interfaces. All the systems I have set up thus far have been pure VoIP
setups.

The system I need to set up should have 3 FXO interfaces and 1 FXS
interface, as well as several SIP phones. I have noticed people
complaining about Digium's TDM cards - are these isolated incidents or
are these cards unreliable? I intend to get the TDM400P with the
necessary FXO/FXS boards - can I expect the installation to be somewhat
straightforward? Any tips to avoid grief?

Would it make more sense to get 3 cheap X100P's and use some kind of ATA
for the FXS? Will obviously save a whole bunch of money, but will there
be significant added complexity?

Here's an option that some might consider, especially in light of the
ongoing problems with virtually all small FXO interfacesthe Zultys
4x5 SIP phone.

This SIP phone includes an onboard 4 port router wit QoS and an FXO
interface. At point of introduction early in 2004 the FXO i/f was only
used as a lifeline. The firmware setup allowed the suer to pass local
calls to the FXO while passing all other calls to * via SIP.
Alternatively, the phone could try SIP calling outboard before falling
back to the FXO.

However, about two weeks ago Zultys released firmware that makes the
FXO available as a SIP reource to *. Calling coming in on the FXO can
be routed to * for transfer or VM purposes. 

It's a little strange since we're accustomed to having the FXO/FXO i/fs
on the server. However, you could bring the POTS lines to the desktops
and into the 4x5 phones. Then have the call pass to * when required.

BTW, the router functions such as DHCP etc can be defeated if desired.
Also, the 4x5, unlike some phones, requires only one registration to
support multiple call appearances. From on registration the 4x5 support
4 active SIP calls and one on the FXO, at the same time.

Michael

P.S. - I'm buying one of these from a friend who doesn't need his
anymore. I had it on loan for a month back in the summer. It worked
well with* but the FXO  * firmware was not yet available.

  Those first 3 all sound like you have a problem with power supply and
  consistency. You don't mention what modules you have in the cards, but I
  bet you have FXS ports and have too light of a power supply for the
  job.  
  
 
 I'm not at the client sites, but my test system BIOS reports (with a 
 TDM22B installed):
 
 VCORE 1.676V
 DDR Vtt   1.344
 +3.3V 3.28V
 +5V   4.945
 +12V  12.544
 5VSB  4.945

And from BIOS you for sure are not loading a driver and you aren't
having to drive the ringing voltage. 

Part of my concern on power supplies is that I have abused them for non
standard functions and know that many of them will pulse the 12v lines
and probably the 5v lines as well if you draw too much power. So
consider the option that your server is running smooth with no activity
and the hard drive(s) spool down. Then a call comes in and asterisk goes
to trying to write to the disk for logging as well as generate ring
voltage. This could cause a low quality PSU to see a spike that it isn't
capable of handling and it would pulse and there is your power alarm.
