I've spent all day today trying to fix an echo problem and I've made no ground whatsoever.
I have Digium TDM400 with 3 FXO & 1 FXS. I've tried this computer at two completely different sites with different phone providers. I've tried compiling & installing different versions of Zaptel (currently running 1.4.0, started at 1.2.9 and worked my way up). I've tried compiling MG2 & Mark, AGGRESSIVE & not. I've played with echocancel & echotraining, starting at 32 & 100, increasing the training up to 1100, 200 at a time, then increasing echocancel to 64, 128, 256 until I've gone through 100 different combinations. I've increased & decreased in different ways both txgain & rxgain. I must be, MUST be missing something, as nothing seems to make any difference. If I increase or decrease txgain/rxgain, I can hear the noise go up or down as expected, but that's it. Below is my zapata.conf, any help would be most appreciated, I'm going crazy. Here's a few questions I have I hope will help: 1. How do I determine which version of Zaptel is running? 2. How do I determine which echo canceller is installed & running (MARK2, MG2, so on) 3. It seems to be only incoming calls that have an echo and only on the inside, the outside never hears one, what does this mean?
