Have you tried the following in zapata.conf? echotraining=800 echocancel=yes echocancelwhenbridged=yes There is a remote possibility that electrical interference on the pstn lines could impact asterisk's echo training process, but don't have a clue how you'd measure it other then to obtain a telephony transmission test set and actually measure the noise level. _______________________________________________ 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
