Using TDM400's here and I have tried everything to cure the echo. I have used the Milliwatt test from the telco and from asterisk to tune RX/TX gain via a patched ztmonitor. What happens is I experience midcall echo. I turned on aggressive_suppressor and it seems to do great. The problem happens with misc. noise around the office will cause it to mute the other end of a phone call while they are talking. I haven't been able to find anywhere in the MEC2 source to limit when it mutes the remote party. It seems to do it with just the slightest bit of sound coming from the room. What are my options besides getting mad and ordering a PRI and a TE100?
