[asterisk-users] Cutting noise and voice

[Eric Wieling]

You cannot echo cancel SIP.  Removing echo must be done before PSTN is converted into SIP.  i.e. your PSTN/SIP gateway.

Very Good day to everybody, I had a problem with an implementation that recently made ​​in my Company, dealing in a Grandstream gateway which will enable echo cancellation but until you hear noise point appears in the middle of words creating noise interference, when you disable the echo in this device may not hear much sound but the echo is uncomfortable.

I added these lines to each sip of my sip.conf, but the echocontinues.

echocancel = yes
echocancelwhenbridged = yes
