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

Send me your questions if you don't understand what i
expect to do .
