Re: [asterisk-users] More Echo

[Jason Baker]

Interesting. I will give that a try. Also, any idea between the difference in switchtype between national and 4ess? All the documentation I read labeled 4ess as ATT, but I didn't try the national to see if it changed anything, like echo or signal quality.

The system below is out of Livonia, with an AT&T PRI as well. Note the rx/txgain entries, it may be useful as well: switchtype=national context=pri signalling=pri_cpe echocancel=yes echotraining=yes echocancelwhenbridged=yes rxgain=-1.0 txgain=-4.0
