Hello, I am using SIPGATE and IVM via VoIP 4.20. I have the two linked but when i call to test I hear nothing. I am sure its a port issue, and I have a router with port forwarding set up up: 5070 SIP 5100 - 8699 RTP and set in the IVM program, but still no sound? Please can someone give me a shout. The route which logs everything sees port 51234, not sure why as that use to be a Teamspeak query port. Any ideas ??
