[Asterisk-Users] Echo Cancellation Feature

[Ryan Thrash]

I would also offer feedback that we too have random calls with echo on 
our end, that can't be traced to a reproducible event. It's very odd 
and can be frustrating, as it's a big distraction for those that don't 
know better. Like a bad cell phone connection when you hear yourself 
talk. For us, this happens in a pure SIP environment on a network 
switch dedicated to Asterisk, a T1 PRI and 18 SIP handsets.

HTH,
Ryan
