I had to turn on the aggressive echo cancellation in the zaptel drivers for mine. Which is much better, but we still get occasional pops.
The funny part is only the asterisk side of the connection hears the echo.

He has not implemented the code to set the coefficients as yet, therefore the expected values are zero's. _______________________________________________ --Bandwidth and Colocation sponsored by Easynews.com -- Asterisk-Users mailing list [email protected] http://lists.digium.com/mailman/listinfo/asterisk-users To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users
