...the odd echo on my PRI lines (not connected through the TE406). It was well within acceptable bounds for the most part for myself and for those who use the system. For everyone having nagging little echo issues that just won't quite go away and you've tried everything else.... use KB1. I really hope after some more extensive testing this goes in as the default software echo can. Congrats, Kris... you have a real winner here in my books. -A.

hi! In your experience what is the best choice for echo canceller ? Which one should work better: STEVE, STEVE2, MARK, MARK2, MARK3, KB1 ?

...;, but what it sounds like to me is a slight echo, but just of one syllable of the word. I've followed the numerous suggestions in the mailing list archives which is what has enabled me to get this far. After trying all the echo cancelers, and all the settings on each I settled on: - KB1 (with AGGRESSIVE_SUPRESSOR) - echocancel=128 - echotraining=600 - rxgain=0 - txgain=0 If I turned up the echocancel to 256 I'm able to eliminate the "buzzing" echo, however, on inbound calls I get a HUGE very loud echo that takes a good 20 seconds to go away (which I don't ge...

Is it possible to run the CVS-HEAD/Stable version of Zaptel (1.2 whatever) with an older version of Asterisk? I'm running 1.09, but I was wondering if I could get at the newer echo cancellers like KB1 and MG2 without upgrading to Asterisk 1.2?

...hanging fruit" audio issues in our Asterisk PBX, we are left with occasional cases of severe echo which we have not found a solution for yet. Our system: - Asterisk 1.2.0-beta1 - TE110P on a PRI - TDM04 and TDM40, but these are unrelated to current echo issues - Fedora core 3 - Echo canceller KB1 Most calls have minimal, acceptable echo levels. But occasionally, we get a call where the echo is delayed by a substantial amount (sometimes around 250ms), and sounds as loud as the remote party. One example: when one number (local to the same CO as our PRI) calls us, the echo on our end is unbe...

Hello I have upgraded our asterisk box from zaptel to dhadi two weeks ago... Since, there has been quite a significant amount of echo when making a call. Only for the local outgoing call, the person on the other side doesn't hear any echo. This is with a TE-110P ISDN PRI card .. I've pretty much took the original zaptel configuration and used it as-is with the dahdi one ; to no

...1 and Asterisk 2 are connected using E1. Echo() is the dialplan application. The problem is the high delay using this configuration: 20 ms only in Asterisk 2. I've read the source code of chan_dahdi, and I think the channel has a 20 ms "buffer" (160 samples). Algorithms like mg2 and kb1 are configured to accept 128 taps (16 ms), so 20 ms is too high. Someone knows how I can reduce the delay to at least 10 ms? Should I change something in the source code?
