I am having a problem with echo and Google Voice. I can call out and receive calls. However, people I call or people who call me complain that there is an echo. I can not hear this echo.
asterisk-10.9.0 installed on Gentoo.
Nortel 1120e IP phone using unistim
Ekiga 3.5.7 softphone with headset using sip
Google Voice using jabber and gtalk
It doesn’t matter if I use the IP phone or softphone, they still complain about hearing an echo. I’ve searched around for an answer. However, most of the echo cancellation faqs talk about hearing an echo on my end. I do not hear an echo, only the people I am calling. They also talk about turning echo cancellation on in the channel where the problem occurs. I looked through the settings and did not see an option for this in the gtalk module. Calling between unistim and sip does not produce this problem. Only calls going through Google voice, and only on the other side of Google voice, not on my side.
At this point, I am looking for any advice or direction in solving this issue.
