Hello Everybody, I am using 3CX with the 3CX Phone software and Linksys SPA3102 for it's PSTN line. I can make outside calls from 3cx phone to outside regularly. The problem is that when I receive a call form outside throuht the PSTN line the call hungs up after 30 seconds. The Detect PSTN long silence is "off", also I have tried Detec disconnect tone to "no" but is still the same situation. On the 3cx server log I see: [CM104001] Call(14): Ln:10413@Linja413 hung up call; cause: unknown Looks like the call is disconnectd by the SPA but I can not ind it why, it disconnect exactly after 30 seconds of conevrsation. I apprechiate any help on this! Thank You!
