Hello, Brian West a écrit: I get no echo on mine.. but you can check to make sure your line isn't reversed. A reverse wired jack can do that. I don't think so but I have tested reversed and it doesn't solve my echo problem Daniel bkw On Thu, 28 Aug 2003, Brian J.

I have a Sip phone, Digium 4 Port FXS, and 3 Digium FXO cards installed into an asterisk server. If I call between the Sip Phone (Budgettone-100) and the 4 FXS ports everything sounds great. If I call out to the PSTN through the FXO cards I get horrible echo, I have even been able when talking loud enough to get a horrible feedback loop going. I have tried 4 different echo cancellers in the Makefile for the Zap drivers and nonoe of them changed the situation. I have echocancel = (Any where from 1 - 256, I have tried alot of different values), and I have echocanelwhenbridged = yes.I only hear the echo start when the call gets bridged onto the outgoing PSTN lines. Is there anything I can do? Brian J. Schrock Hi, For me: rxgain=0.8 txgain=0.8 in zapata conf do the trick. Now the echo is allmost inexistant. Maybe the sound is not very strong but the quality is very good. I have the default echo canceller (no modification in the source files). Tested with a lot of SIP phones (ATA (G.711), X-Lite(GSM), SJ_phone(G.711), Cisco 79x0) and one X100P card.
