Thanks. But what is it associated with. When I do a register and determine that it is NAT'd client, I do a setflag. When I do this, what is this setflag associated with? With the location entry of the registered client? And when I us setflag when I receive an INVITE, is it associated with that INVITE pdu?

It's associated with the full transaction. From start of the routing script to finish.
Each time you make a call through the server, it hits the beginning of the route and goes through to the end (perhaps making hops around to secondary route blocks or failure routes or some such). The flag is global for that duration -- throughout all the route blocks and failure routes.

during save(), the status of the NAT flag (http://openser.org/docs/modules/1.0.x/registrar.html#AEN103) will be stored in the location table. Later (in another transaction), if you call lookup(), the NAT flag will be restored.
This way you can detect if you have to perform NAT traversal for the callee.
