[SR-Users] an issue on terminating dialog for kamailio 4.2.x

[Daniel-Constantin Mierla]

Hello,

the problem is that the callee is behind the nat but you don't handle
the 200ok properly in order to update the contact address. The contact
address stays like 192.168..., which cannot be routed by kamailio when
it appears in R-URI of ACK and BYE.

Be sure you do nat traversal logic for replies.

Cheers,
Daniel
