Re: [asterisk-users] More Echo

[Jason Baker]

Well I tried Doug's suggestion and the echo is now better, but when I call an outside analog line I still get some echo. I can hear my voice in the ear piece of the phone with a slight delay. Is this just a fact of life with VoIP, or is there a better way to reduce line echo? Again, for reference, I am using the VPMADT032 echo cancellation module attached to a Digium TE121 PCI express card. The incoming phone service is a PRI.

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
