[Asterisk-Users] Bad echo on outgoing calls

Depends on the installation; I have a half dozen of these cards with very 
very little echo problem.  You might want to reverse tip and ring in your 
install and see if that helps; I have heard that reversed T&R can really 
screw up echo cancellation.

Also note that more echo cancel doesn't necessarily mean better echo cancel.  
I have echocancel=32 in my zapata.conf and it's far better than 'yes' and 
higher numbers.

When going from my TDM400P to my X101P I seem to have had better luck with 
"echocancelwhenbridged=yes" -- you didn't mention whether you are going 
between two analogue interfaces or not.
