He should also be using ztmonitor and a milliWatt source to make sure his gains are optimally set. Googling for "Adjusting txgain/rxgain site:lists.digium.com" and looking for Kris Boutilier's lengthy post. I found you don't need any additional patches, just the telco's milliWatt number and some time. I know you're looking for a quick and easy answer, but there isn't one. Echo is a problem that affects all TDM networks, and affects any packetized networks doubly so. -A. _______________________________________________ Asterisk-Users mailing list Asterisk-Users@lists.digium.com http://lists.digium.com/mailman/listinfo/asterisk-users To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users
