Hi Javier Yes we are, but the problem only happens in %6-%8 of the calls. It happens in calls that have identical signaling to the ones that don't have the problem.
I have been speaking with Richard Fuchs at sip wise and I am going to try adding the trust address flag to sip wise and see if it helps. That hopefully will make it take the address in the c= attribute more readily. I will update this thread once we push that live. If any one has another suggestions though I am very open to hearing them :). Thanks very much. All the best.
