RE: [Asterisk-Users] Qs about FXO/FXS cards
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. ___ Asterisk-Users mailing list Asterisk-Users@lists.digium.com http://lists.digium.com/mailman/listinfo/asterisk-users To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users

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

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.

RE: [Asterisk-Users] Qs about FXO/FXS cards
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. -Original Message- From: [EMAIL PROTECTED] [mailto:asterisk-users- [EMAIL PROTECTED] On Behalf Of [EMAIL PROTECTED] Sent: Monday, January 03, 2005 7:23 PM To: asterisk-users@lists.digium.com Subject: RE: [Asterisk-Users] Qs about FXO/FXS cards My cost analysis showed that * is a slam dunk for the $ per feature.

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

Re: [Asterisk-Users] Qs about FXO/FXS cards
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- T Jim Van Meggelen wrote: Dorn Hetzel wrote: On Sat, Jan 01, 2005 at 07:23:58PM -0500, Jim Van Meggelen wrote: [...] What if, for example, the TDM400 issues were a cumulative thing?

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.

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'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'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.)

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.

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.

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

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

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?

Hmmm, silly me, error message was in outbound email queue - so here it is again: Dec 31 12:03:55 NOTICE[7145]: chan_sip.c:7486 handle_request: Failed to authenticate user WIRELESS CALLER sip:[EMAIL PROTECTED];tag=83eaec7dcb80f5feo1 ___ Asterisk-Users mailing list Asterisk-Users@lists.digium.com http://lists.digium.com/mailman/listinfo/asterisk-users To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users

RE: [Asterisk-Users] Qs about FXO/FXS cards
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. BTW I take that back. I spent an hour on this after posting my last email, and with a little tweaking, everything seems to be working well now. -- Nabeel Jafferali tel: 416.491.9136 (toronto) 646.225.7426 (new york) fwd: 46990 email/msn : nabeelatjafferali.net ___ Asterisk-Users mailing list Asterisk-Users@lists.digium.com http://lists.digium.com/mailman/listinfo/asterisk-users To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users

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

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

Brian Greul Texas Shirt Company www.txshirts.com 713-802-0369 / 713-861-6261 (fax) 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 -- Michael Welter Introspect Telephony Corp.

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. -- Michael Graves [EMAIL PROTECTED] Sr. Product Specialist www.pixelpower.com Pixel Power Inc.

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. -- Steven Critchfield [EMAIL PROTECTED] ___ Asterisk-Users mailing list Asterisk-Users@lists.digium.com http://lists.digium.com/mailman/listinfo/asterisk-users To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users
