Hi I had a similar issue, digium card with echo canceller. I was under the impression that the EC was turned on by default, while it actually requires explicit activation. in ss7.conf : ; Echo cancellation ; echocancel can be one of: no, 31speech (enable only when transmission medium is 3.1Khz speech), allways echocancel => allways ; echocan_train specifies training period, between 10 to 100 msec echocan_train => 100 ; echocan_taps specifies number of taps, 32, 64, 128 or 256 echocan_taps => 128 -- note that allways is spelt with 2 l You may search some of my posts on this list archive - I had an issue w/ the EC resetting, and some digium staff helped me through this list. Hope this helps J.
