I don't know this part of Asterisk code sufficiently, but you would need to hire a programmer for this anyway. Maybe you should post a bounty into the Asterisk-Dev list I am sure one of these guys would not mind picking it up if you place a bounty.

Another option that is obvious (I don't know SER) is for SER to connect to Asterisk a if it was standard SIP phones - just thinking loud...

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:[EMAIL PROTECTED] ip so asterisk query "sip:[EMAIL PROTECTED]" behind nat (not possible).

How a session between two user agents behind nat
could
keep in the path

|register | | register |
agent1
asterisk|         |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 .

Harry
