OK, I'm trying to solve some recent echo on our Asterisk phones. We have the system running through an Avaya IP Office 412. So the call flow is such:

Polycom ---> Avaya ---> PRI

The echo is rather recent. And only when dialing out the PRI. I've made some changes yesterday to the zapata.conf file but have a few questions.
Here are my settings that I've changed...

echotraining=yes
rxgain=-3.0
txgain=-2.0
echocancel=yes
echocancelwhenbridged=yes

When running /usr/src/zaptel-1.2.5/ztmonitor 1 -v
I see the call audio is nearly fine, except for a few very high spikes. Those spikes are causing my echo. Now is where my question comes in. Since the audio level appears to be high I want to continue lower my gains, correct? Say rxgain=-4.0 txgain=-3.0 etc?

As well, when I make a change to zapata.conf I read that I don't need to restart asterisk to have them take effect. Is that correct? Any other feedback with regards to ech is also welcome. Thanks in advance!
 
Our main PRI runs off a IP Office 412 v3.1
