José A Zamora asked:
You could write the steps used to finally solve the problem?
Sure. :-) 1. Comment with ";" or remove "echo_cancel_level => 64" in zt.conf. 2. make current The problem was no audio in either direction when echo cancelling was enabled in DAHDI (version 2.2.1). The problem occurred, because open_zap was setting the echo cancel level, even when echo_cancel_level was commented in zt.conf. Anthony's change turns off echo_cancel_level, if not specified in zt.conf. That allows echo cancelling in DAHDI to work. -- Russell Mosemann
