I sorry for posting this question again, but I think some of the setup has changed since the last post. I have been using google voice for my home phone and now I have signed up for Vitelity. However, I my Vitelity inbound trunk is not working. A little background: I used the Trixbox setup wizard to try to configure my inbound and outbound trunks. This instructed me to create one inbound and one outbound sip trunks. The inbound trunk: Trunk name: inbound Peer details: type=friend username=uname secret=passwd insecure=very context=from-trunk canreinvite=no host=inbound16.vitelity.net disallow=all allow=ulaw The registation string works: Code: uname:email@example.com:5060 The outbound trunk: Trunk name: outbound Peer details: type=friend username=uname secret=passwd fromuser=ntll_home trustrpid=yes sendrpid=yes context=from-trunk canreinvite=no host=outbound.vitelity.net disallow=all allow=ulaw Outbound does not have a registration string. Extra information: Networking and TCP/IP is my speciality, with that said all my ports are properly forwarded, and my firewall is passing traffic. Also ping test from my PBX goes to inbound16.vitelity.net and outbound.vitelity.net. Port scans show all positive information. My open ports are 5060 - 5061 and 10000 - 20000. Thanks a million!
