My chan_ss7.conf looks like that: Hi, no audio is usually caused by misalligned CICs, but there are other possible reasons aswell. How did your interconnect testing went? Was everything fine with the continuity testing? As for echo, which card do you use? Do you have a HW EC built in and enabled? That's probably the best way to go as far as echo is concerned. -- Jakub Klausa | +48 509 032 888 | j.klausa at ss7.pl | http://www.ss7.pl/ Dane rejestrowe -> http://kontakt.ss7.pl
