[OpenSIPS-Users] Location info when using OpenSIPS as outbound proxy

[Bogdan-Andrei Iancu]

Hi Nauman,

The registration functionality is available for requests only. So, you 
can not register contacts at reply time.

In your case, you have 2 problems:

1) if you do the registration processing (save(location)) at request 
time (UAC->opensips->proxy), you will not know if the proxy will accept 
the registration and if it will not change the expire time (a registrar 
can do that).

2) ideally, for an outbound proxy, you should do the registration 
processing at reply time, once the main registrar accepted the 
registration and eventually made all the changes over it. But right now 
opensips does not accept registration processing for replies.

Nevertheless, I have on my TODO list to make possible registration 
handling at reply time.

Regards,
Bogdan
