Sounds to me as what you want to do require 'a few' code changes to Asterisk. Maybe I am wrong, but this might take some work to get right.

Hello open(ser) asterisk users
Here is what i expect to do :
Asterisk: registrar with public ip port=5050 open(ser): outbound proxy with public ip port=5060
Asterisk don't support IM and presence so i want to use SER because of it's a good proxy:
I want user agents behind nat send registration to asterisk because of it's an ipbx :-)
Look at this diagram when user agent behind nat send REGISTER to ser the contact field in sip header has a private address which one is forward to asterisk for registration.
When user agent are registered in asterisk AOR is sip:user@private ip so asterisk query "sip:user@private" behind nat (not possible).
How a session between two user agents behind nat could keep in the path
|register | | register | agent1asterisk| |ser/nat box | | | 200 OK | | 200 OK | agent2
One box --------------------------- | ---------------- | | | asterisk pbx | | | ---------------- | | || | | ---------- ---------- | | SER |====|NAT box |==== private network | ---------- ---------- ---------------------------Send me your questions if you don't understand what i expect to do .
