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.
