Folks worked on IMS - I have a small query.
As you know, for SIP Registration/Signalling, the SIP signalling will take the path UE–>P-CSCF–>I-CSCF–>S-CSCF.
Once a SIP session is establishled, what is the path taken by RTP packets?
Is it UE–>P-CSCF–>media-gateway or UE–>P-CSCF–>I-CSCF–>S-CSCF–>media gateway?
I am thinking that it is the first one.
