[Asterisk-Users] Random Echo

[Brent Franks]

I have a user that complains of echo for the duration of a ZAP-SIP call.
I have experienced it too, but it only happens randomly.

Is there any way to debug the echo cancellation other than doing a zap
show channel X?

I am using a T100P --> Adtran 750.

Has anyone done anything to successfully stop echo with the Adtran 750?

In my Zapata.conf file I am using echotraining and echocancel=yes.

I also am using rxgain=-2.0.

Thanks in advance,
