[Asterisk-Users] Reduce echo?

[Jeff Noxon]

There's nothing you can do with that setup to reduce echo.

Some of the Eicon Diva Server cards do support echo cancellation.
There will still be echo on these cards for a few moments while the
echo cancellation sets up.  Because CAPI is a high-latency interface,
this is unavoidable.
