[Asterisk-Users] SIP phones unbeatable echo

[Dan Elder]

Hey all again, I'm wrestling with echo problems on our sip extensions. I've
set these items in zapata.conf but tweaking these values doesn't seem to
make much difference


echocancel=yes
echocancelwhenbridged=yes
echotraining=2500
rxgain=8.0
txgain=1.0


are there other settings that can help me tame this beast? Been searching
but not turning up anything that'll work here.

Thanks in advance.
