It is a patch to allow us to capture audio streams in a way that will allow us to debug (and presumably fix) the problem. I don't know yet which versions of Zaptel it will be merged into, but it is small enough that it will likely go into both 1.2 and 1.4. The patch is being reviewed by some developers here at Digium and will then be merged, possibly as early as tomorrow evening. Once that is done we can work with one or more of you who are experiencing this problem to get us audio capture files, and we will supply those to the HPEC code creators to find out what is going wrong. ___ --Bandwidth and Colocation provided by Easynews.com -- asterisk-users mailing list To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users

I will be working on improving Zaptel next week to allow us to do proper debugging of this issue with the provider of the HPEC code; stay tuned for updates, and those of you are experiencing this problem please ensure that Digium Support is aware of you and can contact you when we have the new Zaptel code available for testing.

Re: [asterisk-users] HPEC audio clipping
Both of the zaptel (1.2 and 1.4) drivers I tried were the latest. Are the older drivers working better? Does anyone have a configuration close to mine that is working? -- Michael Boers On 4/6/07, Eric ManxPower Wieling [EMAIL PROTECTED] wrote: Michael Boers wrote: I have recently moved an asterisk system to a new location.

Hi: Greg Siemon wrote: Same issue here as well. Running Centos 4.4 (x86_64) with all updates installed on a Pentium D 2.8 GHz, 1.5GB RAM and TDM800P with 1 x Quad FXS and 2 x FXO ports.

Re: [asterisk-users] HPEC audio clipping
In my case, the rx and tx gains are 0. I will try the 1.4 version for fxotune to see if that helps.

RE: [asterisk-users] HPEC audio clipping
Thanks for the helps Stephen. I was running non standard gains but setting regain and txgain to zero (then reloading chan_zap.so) does not help. I still get the broken audio, in fact sometimes I don't get any audio at all. In testing the server just froze a number of times and had to be rebooted via the power switch. I am using the latest Zaptel 1.2.16 files and the latest fxotune from the 1.4 release and I still see this issue. Very interested to get this working but without the HPEC my server is rock solid (only have to reboot it when I install kernel updates). I don't believe it is my system but am happy to do any testing others may suggest.
