[OpenSIPS-Users] Redirecting REGISTER requests to another proxy

[Bogdan-Andrei Iancu]

Hi James,

it is a know issue that most of UAC do not properly implement 3xx for 
REGISTER requests... Talk to pjsip guys, they are really good and fast 
in fixing their stack.

About other solutions....complicated ones...If P1 receives the REGISTERs 
it needs to deal with the NAT issues and act as a mid registering for 
P2, the real register server. Like UAC registers via NAT to P1 and P1 
registers to P2. You can do this by playing with the contact when 
forwarding the REGISTER from P1 to P2.

Regards,
Bogdan
