Hi!!
I am kind of lost in a scenario..where..
UAC (behind NAT) initiates a session with a UAS (Not behind NAT) through Proxy
(Statefull)..
Now invite goes to Proxy and then routed to UAS.. and response is also relayed
back to UAC as per rfc 3261 and 3581..
The UAC does not use any STUN etc.
However IF UAS wants to end the session with BYE, it will send this request to
Proxy (coz proxy had record-routed), but how shall proxy
route this request back to UAC (which is behind NAT), coz the contact address
which UAC had sent in initial invite contained private IP.
is there any way we can make Proxy aware of this state and try to route request
back to UAC?
regards
Arif
