[Asterisk-Users] brief echo on incoming call

Tue, 03 May 2005 17:24:57 -0700

Running CVS-HEAD-04/12/05-16:39:24 on CentOS 4.0 final installation. I am hearing a brief echo on our Cisco 7960 phones when a incoming call is answered. After a few seconds of conversation the echo disappears. There is no echo on outbound calls or transferred calls. After a search of the mailing list, wikki, and google I have tried the following to no avail.


echocanel=yes as well as 16, 32, 128, and 256
echotraining=yes as well as 800
echocancelwhenbridged=yes

I have also modified the rxgain= and txgain= settings.


Short of recompiling the zaptel with agreessive echotraining can anyone suggest some other things I may be missing?



Thanks,


Gary
