Hi, We had also the echo problem, but when we try to put the echocancellation option, we observe rebootic voice in some call, and don't know if this is related to the echoconcellation option or this is due to the echocan_train and echocan_taps parameters. I need to know if there are some other tunning options. Regards.

For a link, you can specify for example: [link-l1] ; Echo cancellation ; echocancel can be one of: no, 31speech (enable only when transmission medium is 3.1Khz speech), always echocancel => 31speech ; 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 Best regards Anders Baekgaard On Thursday 22 March 2007 07:53, Vernier Umali wrote: > I have an asterisk box connected for sometime now to an ss7 network. > One of the issues I have sometimes is echo.
