Hi, Uncomment the following line in the makefile in /usr/src/zaptel
KFLAGS+=-DAGGRESSIVE_SUPPRESSOR Do a make clean install in this directory and reload wcfxo driver (rmmod and then modprobe). Try again and see if there is any improvement.

The echo canceller algorithms aren't doing anything. We get extreme echo during the conversation, it appears even before the call connects, the echo is there... This only happens with SIP to/from WCFXO (analog POTS). Looking at the Zaptel configuration: /etc/asterisk/zapata.conf: echocancel=yes echocancelwhenbridged=yes rxgain=0.8 txgain=0.8 (although none of the above options seem to make any difference). Is there any debugging we can turn on to see what the problem may be, this definitely will hurt production of this environment.
