I've never dealt with an authenticated SIP trunk before and I'm having some issues. I was wondering if anyone has had a similar experience. I already have 2 SIP trunks from ITSP-1 that do NOT require authentication. These are working fine and have been for years.
We are adding ITSP-2 and their SIP service DOES require auth. I've followed their integration guide (which left a lot to be desired) and their acceptance team is telling me my auth is coming from our private class A address. Our CUBE is in HA with an inside (10.x.x.x) and outside (public) IP address. They are seeing REGISTER messages sourcing the inside VIP. I was looking around for an auth BIND statement or something like that, but I haven't had any luck. Any pointers? Thanks, Nick
