If I talk louder, I start to get what sounds like a partial echo. If I yell, I get a definite echo. It almost sounds like the card has an odd gain problem on receive. The echo you hear of yourself at high volumes I'd call normal with the software echo cans. Oh yes -- Digium also has TE405Ps and TE410Ps *with* onboard hardware echo cans now. I have one coming in. I forgot about the loopback test; use zttool and throw the span into loopback, do you see errors? When monkeying with the echo cancel, I never really noticed a difference. I would even reboot the machine between changes to see if it made a difference. echocan's a finicky little thing. echotraining does work but I never use it because the delay at the start of the call is unacceptable to me (most of us have headsets so the delay between picking up the phone and getting it to your ear is almost zero). The agressive echo canceller basically turns the phone into a half-duplex system. It's a brute force way of eliminating echo. :-) I am running this on Fedora Core 1. I will try any OS you recommend, but I have always had great luck with RH type distro's. I keep 400 and 500 day uptimes on those machines and they run many, many services. Uptimes would be higher but it seems whenever I find a good place to work, they close up or I move. Admittedly, I don't use RPM's for the core services, I typically compile those myself. I also shut down every module and service I don't need. I did alot of reading and it seemed like Digium cards were the real deal and I also found many users that had luck with the same setup. Should I try a different approach/OS/system? Stability isn't the issue here; it's interrupt latency and kernel delays. Personally I run Slackware for everything but I am certain there are many people here running FC1 for their systems without any issue, so at this point I am not suggesting dropping it. I'm not sure whether those who are running FC1 are running it with Fedora's kernel or with a stock kernel, but I *have* seen people with distro-specific kernels have problems that disappear when they use a stock kernel. Which motherboard are you currently using? Which have you switched to for the test? The great thing about Linux is that in most cases you can (and I have on *many* occasions) pull the hard drive out of one system and install it on a totally different one and it just works. Perhaps some minor tweaking of ethernet drivers but for the most part there are no hassles. -A. ___ 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

I still get static noise when the other person speaks. If I talk louder, I start to get what sounds like a partial echo. If I yell, I get a definite echo. This sounds vaguely similar to a problem I had over a year ago. I progressively solved it by: *) New motherboard/CPU (from via based AMD XP1800 to via based dual AMD Athlon MP based) *) Lots of playing with echo canceller options Those two solved the static problem, and most of the time, they solved the echo problem. However, I recently had the opportunity to swap my card for a new TE4xxp card, and found that all my intermittent problems vanished (timing slips, frequent red alarms, dropped calls, HDCL errors). After a few more weeks, I got the card RMA'ed, and now everything is perfect. No frame slips, no echo, no static, nothing at all. BTW, the 'static' in my case was only ever heard by the PRI party, the sip/etc user never heard it. The way it seemed to work is while I talked, the remote party would hear me overly amplified + some distortion factor... Even though the actual volume wasn't loud... It made it difficult to have a conversation, and some people would simply hangup (annoying after you have been on hold for 40 minutes). However, this wasn't apparent on ALL calls, it only affected some calls, but always the same people were affected. So, it seems to me that the real problem was some sort of marginal card, but by throwing a better motherboard/CPU at it, I was able to get better performance... My suggestion, try another motherboard, and then contact digium, get them to run zttest and also do a loopback test. It was the loopback test that got them to replace my card (it received less than 10% of the packets it sent without error, the other 90% or more were errors! Honestly, I'm surprised it even worked some of the time). Hope that helps you somewhat...

[Asterisk-Users] Static and echo on PRI
I need some serious help!! I have been in the process of building an
Asterisk system to replace a Cisco Call Manager. I have most everything
setup, but only got to test the PRI today. To make a long story short,
my Call Manager is half broken and I need to go live with * a lot sooner
than I expected.
Here's where I am and what I tried. I am using all Cisco phones, mostly
7940's and 60's in a SIP configuration. All internal calls work with no
issues. I have a TE405P for the PRI and a TDM22B for my paging system
and whatnot. I am currently only using one PRI on the quad card. When
calling out on the PRI, I am getting static and some echoing. I have
tried various orders and values for the txand rxgains, echocancellation
and nothing seems to help. I get the staticy noise only when sound is
coming in, like when the other is ringing or when the other person is
talking. Complete silence the rest of the time. I get different
amounts of echo when calling out, the person on the other end says they
hear no echo or static at all, just on the SIP phones. I made sure that
I have no IRQ conflicts (output below) and my CPU usage seems to be
fine, plenty of horsepower remaining.
Here are the parts of my configs that I feel are relavent:
/etc/zaptel.conf

difference.

I tested and I do in fact get from 40-50% system util every 5 seconds or so. After removing the wctdm module, the system util drops to 0 and stays there. I have not loaded the wcfxs and wcfxo modules because I could never get them to work right. I instead load the wctdm and it has seemed to work fine. I only need to make the fx port to the paging system work and the others can stay idle. What modules and order so you suggest. Here is what I load in this order: wct4xxp wctdm Thanks!
