I have a AS5300 setup as PSTN Gateway. It works fine with VOCAL. Now I'd like to connect SER to this PSTN gateway. I added following line to the default ser.cfg file: if (uri=~"^sip:1") { log(1, "Forwarding to PSTN\n"j); forward(189.101.110.132, 5060); break; };
This will allow any dialed number starting with 1 being forward to PSTN gateway. But it always give me busy signal. Can anybody tell me what's wrong?
Here is my whole ser.cfg file:
