Hello, I have a problem with my X100P card.... I have connected it to my asterisk and it works.. but I hear an echo.. I?ve tried echocancelation... echotraining.. and nothing happens... I?ve changed the values from the rx and txgain.. from -40 to 10 and it doesn?t changes anything.. Don?t know what else to do.. [channels] language=en context=default signalling=fxs_ks channel => 1 usecallerid=no hidecallerid=yes callwaiting=yes callwaitingcallerid=yes threewaycalling=yes transfer=yes cancallforward=yes callreturn=yes echocancel=yes echotraining=yes echocancelwhenbridged=yes rxgain=-4.0 txgain=-4.0 group=1 pickupgroup=1 immediate=yes this is my zapata.conf... Any ideas? what is missing? Oh.. I?ve tryed to see the levels with the ztmonitor to see any change.. and nothing changes.. Thanks for reading, Danko
