[Asterisk-Users] Echo cancellation problem

[Giuseppe]

Hi!
I'm here again with echo canceller problem... :-(
I think I've done everything to enable echo canceller feature, but it 
still doesn't work...
Can anybody tell me if there is some error or something missing in this 
configuration please?

I'm using Eicon Diva Server 4Bri.
