Ugly echo cancel, with Bristuff/Zaphfc
...'m using bristuffed Asterisk with ISDN/ZAPHFC
I have VERY ugly (outgoing) sound through ISDN/HFC if echocancel=yes in
zapata.conf, but without echocancel I have bad (incoming) echo
Through PSTN/FXO sound is ok with or without echocancel.
I tried other echo cancellers (in zconfig.h) two times:
ECHO_CAN_KB1 (this was default)
ECHO_CAN_MARK2
ECHO_CAN_MG2
after any change I compiled (make clean all && make install) all drivers
which are bristuffed, without recompiling Asterisk (should I?), but...
... I always have EXACTLY same (ugly) sound and same (appearing of) echo
cancelling.
Seems to me...

TDM04b and echo
We have occasional echo, mostly on lines that come across as quiet.. I am
trying to troubleshoot how to disolve the echo. i have tried the steps on
voip wiki, but have not recently been able to make any difference.
the echo isnt horrible most of the time, and seems extremely random in
that i can call a number once without echo, then dial the same number a
second time and get echo.
