[SIPForum-discussion] Media Path

[Sudhakaran, Binu (NSN - IN/Bangalore)]

Hello All

Can any one please explain the media path in IMS call.

Lets consider the following Access Elements

1.  PSS user (IP phone)   --> Directly between U/E's or
U/E(a)->P-CSCF(O) -> P-CSCF(T) -> U/E(b)
2.  PES user (Analog phone)  --> U/E -> Access Gateway -> AGCF -> U/E
3.  PES to PSS  --> U/E ->Access Gateway-> AGCF -> P-CSCF -> U/E
3. WLAN  --> U/E -> PDG -> U/E
4. PSS to PSTN  -> U/E -> MGW -> U/E

Please share any document if you can.

Regards
Binu.S
