I'm trying to improve echo for all incoming calls that come into Asterisk via PTSN onto a TDM400 card and then on to a SIP phone. The echo starts off quite loud with about 1/2 second delay and after 10 to 20 seconds it is cancelled. I've tried altering various settings in /etc/asterisk/zapata.conf but cannot seem to improve the echo situation beyond what I've described above. My echo settings are currently set like this:
echotraining=yes
echocancelwhenbridged=yes
echocancel=256
I read somewhere that 'echocancel' increases in powers of 2 like binary (ie: 32, 64, 128, 256, etc) - is this correct? Am I being too idealistic by wanting less echo than what I've described above? How has everyone else got their echo cancelling set? Is there anything else I can try?
Other than playing with the above variables, I've tried a couple of different handsets without improvement.
Many thanks,
David.
