I am trying to get a SIP trunk working (Generic provider), I cannot get the SIP trunk to register. I have entered the debug commands, buit I see nothing in the log as far as standard messages. I have one dial plan setip in CCA that will use the SIP trunk first for a 1888 pattern, all other calls use SIP last (preference).
I know I am missing something simple, I just can't figure out what. I've got the upstram router and firewall set to watch traffic, but I do not see the SIP request (either tcp or udp) going out to the ITSP.
The UC520 is setup on the LAN on a regular port (not using firewall), and ACL 2 is set to allow the SIP Trunk provider to come in, but no hits.
If I tie up all the PSTN lines and try to dial out I get a quick busy. I checked the log and I am getting a: DisconnectCause 3 , DisconnectText no route to destination (3): error. It's like the dial plan is not taking affect.
Any help would be appreciated.
