Hello!
I got the following problem. My 200 OK with SDP sends the private ip
of the B-Leg party.
Kamailio is multihomed (pulic/private address) in front of an ivr system.
222.222.222.222 public ip kamailio
172.20.100.74 private ip kamailio
172.20.100.61 private ip ivr
217.217.217.217 public ip uac
172.20.100.203 private ip uac
U 2012/04/13 13:56:57.307314 222.222.222.222:5060 -> 217.217.217.217:42885
