Are you registering or using a static IP to the ITSP? Are they sending the calls to port 5080 or 5060? If you register does the provider allow you to confirm ip and port they see you registering on?
It would appear (and you can confirm) that the call is coming in to port 5060 from the ITSP in the initial invite on inbound calls. Is you NAT static port NAT (symmetric ports) or dynamic?
