Hi Brian,
the problem is not the private IP in the contact, as opensips properly
saved the source IP (of the REGISTER) too -> see the Received field. So
the Received field will be used over the Contact for sending the
requests to UAC.
Now, what probably goes wrong in your case is that when using TLS/TCP
(connection oriented protos), after the REGISTER, the connection is
dropped and opensips cannot open later a TCP connection behind a NAT
:(....By default opensips closes the inactive TCP connections.
To make opensips to keep the connection (even with no traffic going on),
see the tcp_persistent_flag:
