Re: [asterisk-users] modem config & pots & documentation

[Givon Zirkind]

hi,

i'm looking for documentation on configuring asterisk to work with a modem that 
should work with an analog line.  i don't see the info in the handbook or 
reference manual or o'reilly's.  any references and/or links, much appreciated.

thanks.

You understand perfectly fine the situation :) . I'm not saying that
Paraguay has the worse economy in South-America, but we need to work much
harder to get latest technology or to mount a tiny/small laboratory.

You will get amized if you see the things that we have done with pieces of
hardware considered as garbage in USA :D

Yes, they changed their name to Copaco for Compania Paraguaya de
Comunicaciones. It's basically the same company ruling the whole country. :S


Thanks to all for answering my question.

At the time they were. Nowadays they cost more. Those specific modems
are now obsolete and not manufactured anymore.

This question has been answered many times, but just for the fun of it
I'll answer it again:

If PC modems had been ideal telephony cards, we'd still be using them.

My own experience with using modems as FXO devices (long before I became
a Digium employee) was that they were awful.  I encountered problems
with echo, half-duplex audio, and lack of far-end disconnect
supervision.  All of those problems are solved with most modern
telelphony cards (except for the ultra-cheap cards, which are still just
modems).  To put it frankly, I wouldn't wish one of those modems on my
worst enemies.

I understand that the cards are disproportionately expensive in many
parts of the world as compared to the United States, because of the
difference in economies. I spent a couple of years in Paraguay in the
mid 90s, and know what it's like to pay outrageous prices for
specialized electronics just because they have to be imported from other
countries. (I'm guessing that you're from Paraguay, based on on the
monetary conversion you gave.  Does Antelco still dominate the telco
market in Paraguay, I wonder?)

That being said, the cost per port of the Digium cards (or any of our
competitors who design their own cards) is still much lower than what
you'd pay for traditional telephony cards, such as those manufactured by
Dialogic or Aculab.

I know that probably doesn't help you afford to be able to buy a more
expensive card, but hopefully you have a better understanding of why we
don't use modems as FXO devices.  If your time and sanity are worth
anything at all, it's a worthwhile investment to buy a good solid
telephony card.

I did not know that the price was that low. Anyway, for people living really
far from USA the price gets incremented twice or more and this is without
considering the conversion between currencies.

1 $ = 5100 Gs., not cheap at all.

the digium single fxo cards and clones for about $10 ARE modems.
you can get a sip gateway fxo + fxs in one box for about $50

really - how much cheaper do you want ?

Try setting the modem to 9600 baud.  It will probably work.

Is it bridging the Zap channels?  We have asterisk doing FXO-FXS modem calls 
working fine, the key is making sure the channels are bridging and EC is NOT 
turning on.  If you have anything preventing that the modem calls won't work.

I think asterisk has the ability to detect fax tones and disable echo
cancellation for those calls. I don't know if that is the case with a
regular modem call. I'd check to make sure that echo cancellation is
disabled on the extension the modem is plugged into. The only other idea
is to try connecting at a lower speed (I would think this would happen
automatically though).

I think asterisk has the ability to detect fax tones and disable echo 
cancellation for those calls. I don't know if that is the case with a 
regular modem call. I'd check to make sure that echo cancellation is 
disabled on the extension the modem is plugged into. The only other idea 
is to try connecting at a lower speed (I would think this would happen 
automatically though).

Re: [asterisk-users] MODEM (data) througt asterisk ?

[Time Bandit]

Is it possible to connect a modem to a remote service through asterisk ?
Basicly to ilustrate : Accounting department need to connect with analog
modem to their bank to order some wire transfert.

Modem <-> Chanel Bank FXS <-> Asterisk <-> TDM2400 FXO <-> Modem in
remote site.


If you get it working you're lucky. Digium's official statement on the
TDM2400 is "that card as been designed for voice calls, we don't
support data calls"

You would have better luck with a Sangoma A200

It's only *remotely* possible if everything's G.711 all the way
through, I think.  If there are any analog transitions in the middle
(and possibly even if there aren't) you won't get anything over
33k6bps, and probably less than that.

*Any* phase non-coherence will break anything faster than 202/212, I'm
pretty sure.

Re: [asterisk-users] Modem calls

[Time Bandit]

 I need to pass modem calls through a TDM400 card. Conecting the modem to
the FXS port (ZAP/1), it should be put through the FXO port (ZAP/4)
directly.

According to Digium, Fax calls (and modem calls) are not supported on
the TDM400 or TDM2400. They are designed for voice only. If you get it
to work, you're lucky.

Sangoma test all their cards with faxes, so maybe you should try their card.

For your problem, run zttest and adjust everything to try to obtain
100%, this may make it work.

How to establish successfully modem connection? Has anybody tried innovaphone IP21

They say that fax works with their ATA, maybe modem connection will work also...
 

Many people say their ATA supports T.38, when it has no T.38 support 
whatsoever. VoIP boxes are advertised about as honestly as used cars.



So, how to establish modem connection?
 

By luck, maybe. The only solution that looks like it should be fairly 
solid is V.150, and I've only seen that on Cisco boxes so far.

I think that timing issues will kill you, but if it were going to work 
you would want to use ulaw all the way around as your codec.


a better option would be to use more traditional terminal server/remote 
access server type hardware off of an actual copper pstn line.


you can pick up terminal servers off of ebay if cost is an issue, such 
as lucent max 4048s and cisco 5400s.  voip just is not a good way to

RE: [Asterisk-Users] Modem Over IP: solutions ?

[Carlos]

Hey jean,

I have had to deal with the same situation many times what we have come to
the conclusion is you can actully get them to work only under the 4-2
signaling that the alarm companys use.  Just about all alarms now are set to
use contact id which we have found out that we send the data ok but we don't
get a kiss back telling the alarm to silent.  Note the different between 4-2
and contact id are 4-2 basically calls and says there is a issue here.
Contact id will call and say there is an issue on the 4th floor room 410
closet.  Basically with contact id you get spacifics of the issue.  Note set
the alarm speed to as low as possible.  And in some cases the alarm comapnys
are ass's and wont change it to 4-2 because they have to re id everything.
Oh yea and when testing make sure you call the alarm company and put it in
test mode the fire dept dosnt exactly like it when the get false calls.

Nope, a t100P is a T1 span. Nothing generic there.

The voicemodems that are "supported" are winmodems that happen to behave
similarly enough to the X100P card that they can be dealt with the same
way. Since winmodems move all the DSP work into the main CPU, it means
they are mostly simple PSTN digitizer. Instead of hooking DSP code to
the digitized audio path, asterisk just uses the audio.

Trouble is, most winmodem companies keep the implementation details very
quite. If you can't get that data you can't get it to work.

Next trouble is that no one here gets any benefit from your cheapest way
to play route. In fact your cheapest way to play is a detriment to our
community as you are likely to have a very bad experience and either bad
mouth the software because of your experience, or you may never get past
the basic user position and are just an occasional support drain. All
this without having contributed back to the community. There is a chance
you might move beyond that point, but it isn't likely.

So try and make a convincing case for anyone to beat their head against
the wall to support a low port density device that is unlikely to be
used by a large portion of the community and is not going to benefit
either the writer or the main supporters of asterisk.

I believe that is basically what the generic t100p is.
Also, several other voicemodems are already supported
by asterisk.  To my knowledge they are all FXO ports.
I don't believe there are any modems that can provide
FXS ports.  If someone knows of one, I would be interested
in knowing about it.

Most modems don't operate at full-duplex. A normal modem can be used to send 
voice, then switch to recording voice, but it can't send and receive

None of that tells you anything about the chipset. You may want to

Fair enough. I didn't mean to lecture you. My point was only that
support costs money and that "expensive" is always relative to your
needs. I am not blaming anybody for buying cheap fax modems and use
them as Zaptel FXO cards, but I am not blaming Digium either for their
decision to bundle otherwise available electronics equipment with
support. I think it is a fair value offer. Nobody is forced to take
that offer, but the offer is there and it is good that it is there.

It's got nothing to do with the brand of the modem. The chipset is
what matters. The Zaptel wcfxo driver is specifically written for the
Intel/Ambient MD3200 chipset. Nothing else will do.

Of course, you can always write your own driver for a different chipset ;-)

Fax modems using the MD3200 chip are gradually being phased out of
production. These days, the Connexant chipset is far more common in
fax modems.

> or any of the wildcard's (wich are pretty expensive)

Don't forget that you get both a "works with Asterisk/Zaptel" warranty
and installation support. This means Digium will replace the card if
it doesn't work with Asterisk and Zaptel. Other vendors will tell you
that the modem is a modem is a modem and as long as it works with the
winmodem drivers as a modem on Windoze, they won't accept that you
have an issue. It also means that if you get stuck, you can call
Digium free of charge (dial extension 500 in the demo of the sample
extensions.conf for a free internet IAX peer-to-peer call to Digium)
and have them help you get it working. They will even log into your
asterisk box and build/install/configure the Zaptel drivers for you.

Before this background, you may find that this is a good deal worth
considering, even though it may look expensive at first sight,
especially if you are doing this for the first time.

I did try putting a [remote] context in, but the error message was

The error seems to be wanting to put it in the [default] context, no

I'm wondering what the error means by "invalid extension 's'", am I

RE: [Asterisk-Users] Modem[i4l]/ttyI0 sent into invalid extension 's'

[Ian Johnson]

G'day Dave,

I did try putting a [remote] context in, but the error message was 
indentical.

The error seems to be wanting to put it in the [default] context, no 
matter what I put in modem.conf

I'm wondering what the error means by "invalid extension 's'", am I 
supposed to have something else, I've tried putting in the calling MSN, 
as:

[remote] and in [default]
exten => 12345678,1,Answer

But no joy.

Sorry about the legal rubbish attached to these e-mails.

's'


G'day,

New to Asterisk alert!

I have a Netjet card running on linux 2.4.27 kernel using the HiSax
module, and trying to use it for incoming/outgoing calls from *.

I've tried playing with modem.conf and extensions.conf every which way
I can think of, using samples and whatever I can find off the net, and
I get the same message everytime I try to dial in.

The complete message is:

pbx.c:1868 ast_pbx_run: Channel 'Modem[i4l]/ttyI0 sent into invalid
extension 's' in context 'default', but no invalid handler

modem.conf:

[interfaces]
context=remote
driver=i4l
type=autodetect
stripmsd=0
dialtype=tone
mode=immediate
msn=12345678 (not the real number of course)
device => /dev/ttyI0
group=1

extensions.conf:

Is the sample extensions.conf, at the moment.

Any ideas/solutions would be great!

Thanks.

Ian.

Unless a number of conditions are met, modems above 1200bps over IP are 
somewhere between quirky and non-functional. You won't get anywhere 
unless you use an a-law or u-law codec. Even then, timing issues and 
data slips can cause much trouble. Successful FoIP usually converts the 
modem audio to data, and sends that over the IP channel. The T.38 spec 
supports this. I don't know of a similar spec for other modem uses.

RE: [Asterisk-Users] Modem Calls

Scott,
I haven't done *any* research into this but.. I'm using a Sipura2000 and
I have my laptop modem attached to it. I'm forcing alaw or ulaw encoding
on the line. As soon as the modems begin to "train" I get what sounds
like "static" instantly "come on". Very unusual. Not sure what the
source of it is yet.. Don't laugh, I made my call out on FWD.. :) So I'm
not too confident of it working. Let us know if you get modem calls to
work. I'm interested as well.
Thanks,
Brett

Do you really know what you are asking? You say you have a modem
connection, and then you say you want to use text to speech?

Your problem will be related to the fact that a modem call over a VoIP
is not necessarily stable. If you only need 1200, I'm sure you might be
able to discuss with Steve Underwood about changing the tx/rx fax app to
be a modem only app. At that point you could dial in to a local port
with a software modem, convert to your text string, and send it to the
other side. On the other side you can then push that though another
software modem to the line out. 

Just remember that G711 uses around 80K bandwidth to send 1200.

RE: [Asterisk-Users] modem to modem calls through asterisk

Replacing my zhone channel bank with an Adtran 750 has fixed my modem -

I don't know whether this is something unique to zhone channel banks, 
my particular zhone channel bank or my  installation/configuration. 
Regardless, it is good to have identified the problem.

Because modem drivers do not allow full duplex sound. This is a
limitation of the interface chosen by the implementers of the
specification. I'd about lay money they did this to not cannibalize
their higher profit telephony card market. 

In the case of Digium's card, they wrote a driver that no longer
contains any protected(patented) code for modems, and just exposed the
audio in both direction and the telephony sensing. This allows them to
bypass large chunks of code that would sit dormant and just be in the
way of the asterisk system.

So the extra you pay is in part helping Digium repay their development
costs up to this point, both in the driver and in the application. The
other part you are paying for is 1 hour of support from Digium, and a
bit of a free pass from being flamed on this list for scabbing parts.

So please support Digium and their fine network of resellers by buying
parts from the authorized channels. The alternative may be cheaper on
the wallet, but not on your soul.

'These' people don't bother reading, cause when they search for list

If all you people put your efforts together to create an easy to use web

From what I've been told, the X100P has full-duplex audio while 
standard voice modems are only half-duplex.

An X100P will not help him if what he wants to do is connect his
Asterisk server to his ISP over dail up.  His question could
be interpeted as "Will Asterisk work with a modem card over a
dail up connection?".  

Or, he culd be enquiring about the sound-modem channel driver

We don't know what he wants.

Could you be suffering from an extra digital <-> analog conversion?
Each conversion between analog and digital hurts performance.  (56k
modems are faster than 33.6 modems because there is no digital <->
analog conversion on the ISP side.)

I have PRI lines and just few days ago, I posted a reply to subject:
"Echo Cancellation, TDMoE fails, X100P works" that includes a detailed
explanation of my setup that runs v.90 modems at full speed through *.

Flame wars, Steven?   I don`t quite remember it getting so violent, but then
maybe I slept through some of it ;-)
Sound Card and Modem, though?   Pain in the BUTT!  (need to highlight, here,

you have the will, but that doesn`t always make it a good idea.

This depends on if you have consistent latency and otherwise no jitter.

On my 12 hop link with the office over a cable modem, it is iffy to get
a modem connection up. The connection occasionally claimed 14400, but
never was over 1200 in actual output. So again, this is chancy at best
and in the end will result in longer calls between fax machines. A cheap
modem, and a $10 scanner will solve the problem and keep you faxes going
out fast.

Fax with G711 works fine. Modem will be slow, but if you really need to
use it slown them down to 28.8 or 33.6

unless you are using standalone fax units for the scanning, then you
should be able to. The scenario I laid out above was for specifically
this case. Drop a cheap flatbed scanner in to capture the image, then
send it to hylafax at asterisk2 location to hop a local modem to a FXS
port and off to the net. You can then receive incoming faxes via email
or similar and then choose what to print.

If it is on a specific non shared port, then you can set it up in a
context that uses a different username and password to connect, and in
that definition disallow all and allow ulaw. Just know that this method
is spotty, and may not work because of problems in the fax protocol and
timing needs. search archive for very good explanations of this problem.

I can't. Because asterisk1 is at a remote site. And the only access to PSTN at 
this remote site is trough asterisk2.

Is it possible to config asterisk1 to change to g.711 only when a fax 
transmission is detected?

If asterisk2 is your only access to the PSTN, then it doesn't make a lot
of sense to do fax over VoIP. Put a couple of modems on asterisk2 with
matching FXS ports and learn to use Hylafax. You will get better
performance out of the faxing and potentially lower bills. Also it is
more flexible. Not to mention that the bandwidth over VoIP to make data
quality calls is around 80k of VoIP to get flakey 9.6k. Do you need to
waste 10x bandwidth for sub par functionality?

This is WRONG.   Please lookup the (AT) VTR command - simultaneous voice
transmit and receive that gives full duplex for modems that support it
(including iNTRA2/4/8 in Australia, according to the manufaturer)

I spent a long time researching this (just try googling for VTR and see how
many Video Tape Recorders you will find...) some months ago when I first
started talking about using full duplex voice modems.
All this time I thought you kept ignoring me because of financial reasons
(ie maybe you would be getting the zaptel approved for australia) not
because you thought I didn`t know what I was talking about ;-)

Check these links:
http://www.vee90.net/atcom/BCM/v92/BCMV92_Modem7.html
http://pcdesguide.org/pc99/chapt19.htm which references the the ITU-T V.253
standard - "V.253 includes small corrections to TIA-695 and adds provisions
for bi-directional, digitized voice over the serial port."  (personally
afaik full duplex voice over serial sucks however - not a problem with PCI
cards tho)
http://www.vocpsystem.com/vgetty_modems.php?mode=function - the best site
(which I just spent the last half-hour finding again...)

Re: [Asterisk-Users] Modem => Serial ?

The problem with the few softmodem drivers I've dealt with is that parts
of the driver are _NOT_ in source form. The parts that are in source
form are basically a serial interface to the dsp library that does
direct hardware access as it would have kernel level privs from having
been called from inside the kernel. 

I'm interested in documenting a dsp library that is available for a
software modem and seeing if it could be a resource for asterisk to
create a modem interface. But this is a project probably for the
fall/winter.

With a software modem, you cannot bypass AT commands and directly acces the
hardware for voice applications, as you have the source code for the modem
driver himself?

The problem is using the AT command set, not whether or not serial
communications can carry voice. Remember that T1 is just a really fast
serial line.

The AT command set is a remnant of low power computing. You issue a
command to get started with voice mode. Then you set it in record mode,
and look to see if there is incoming audio. Then you issue a command to
send audio when you have some in your queue.

Actually Dan, you are mistaken here, many serial fax/data/voice modems
come with answering machine programs which tell the modem to
send the voice data through the serial line.  Also the vgetty
program in linux does the same.

Hi,

Serial voice modems use separate jacks for audio in and audio out.
The audio stream cannot be passed through the serial line.

Re: [Asterisk-Users] Modem connections

You are right on the modem - modem in the channel bank.
I tried the 'd', didn't make a difference. I also played with 
rxgain/txgain since the FXO did seem a little 'quiet', no luck.

Anybody have any ideas? If I use the same modem/cabling direct
to the wall jack, it will train.
