Let me get this straight

All you are doing is registering the devices with SER (below you have mentioned asterisk, and then you say they goto ser) Once they are registered to ser you wish to send them to asterisk...is this correct

If so, this does not seem to hard, NAT ius dealt with in ser, I use mediaproxy, others may use nathelper, so before you send to asterisk take care of NAT issues in SER and then send to asterisk.

Paste config, in pastebin, and also a ngrep of the call debug.

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
