I have two VOIP providers VoicePulse and Verizon. VoicePulse uses a Supra 2000 and Verizon uses Linksys PAP2. I can make and receive calls with Voice Pulse. The Verizon service I can always make calls but sometimes times the phone rings for inbound the other times when it doesn’t ring the user ends up in voice after five rings. I have tried two different configurations with the service, I create a service called ANY which has all ports to all ports and a Verizon which has specific ports and services. Ether configuration gives the same results VoicePulse works and Verizon doesn’t.
Any ideas would be great.
