Not sure now if dialog module is fully required for all the cases...
It's just required if you want to mantain nat keepalive for calls
initiated by non registered users.

Imagine a presence agent machine (behind NAT) subscribing to the
presence of some users without registering. How to mantain the
keepalivee in Kamailio (without using nat_traversal module)? The dirty
solution would be decrease the notification interval, that of course
would be a wrong choice.
