Hello! We are trying to setup a SIP trunk on CME 4.2. Having done this a bunch of times before, we went about doing it the usual way. (no registration) Unfortunately, this particular carrier insists on using a non standard SIP Port. So instead of 5060, they are using 5070. I tried specifying a session target of ipv4:xxx.xxx.xxx.xxx:5070 on my dial-peers but that didn't work.
Debug CCSIP All shows nothing on inbound calls. If I do a debug ip udp, I can see the inbound traffic on port 5070, but CME does NOT recognize this as SIP traffic.
