[asterisk-users] Octasic echo cancellation

[Sebastien Leclere]

Hi,

I'm currently testing SoftEcho, an echo cancellation software for 
Asterisk from Octasic. I noticed an important increase of the quality of 
my coms, but I still have a few echo problems.

There is an ERL parameter which corresponds to an initial ERL value 
probably to optimize the echo training or something in that kind.

Is there a way to monitor, using one of the zttools, the instant ERL 
value, to be able to set this parameter correctly?

In that purpose, I would like to know where do the echo cancellation 
take place in the communication chain, is it after or before the 
amplification  by the Rx/Tx gain parameters? Will this gain apply on the 
echo cancelled signal or on the gross signal?

Anybody with experience on this product could give me some advice in the 
aim of removing all trace of echo?


Thanks by advance

Sebastien
