Hello all, I am new to 3CX (been using Asterisk forever) and am looking to setup a test server to play with. I am having trouble however getting inbound calls working using Vitelity as a VoIP provider. I have set everything up and it is reporting as registered in Line Status, but when I try to make a call to the number of the line, it is failing with CHANUNAVAIL. I have contacted Vitelity and they are reporting that I am not actually registered to their servers at all. I have a sneaking suspicion my ISP is blocking port 5060 traffic (seeing as they offer their own VoIP service) and I am wondering what settings I need to set in order to run inbound calls/register through a different port. My outbound and inbound register and proxy are set to vitelity's servers on port 5060 as that is what tehy are expecting but they said I should be able to receive calls on any port I choose. Anyone able to get Vitelity working, or any provider working on another port? I tried changing my SIP port in the general settings and restarting but that didn't work. Any help would be greatly appreciated!
