Yes. For your own purposes you need to use a bflag per contact.
What I meant, is that for its internal purposes when it comes to keepalive
endpoints, the nat_traversal module does figure out automatically without
you doing anything, if the destination of an INVITE needs to be kept
alive during the call.
