scope:
The present document gives examples of the session setup in the IM CN subsystem based on SIP and SDP.
These signalling flows provide detailed signalling flows, which expand on the overview information flows provided in 3GPP TS 23.228 [2]. The flows focus on a basic session setup, i.e. no flows will be provided for topology hiding, for sessions with IBCF involved or for sessions having certain features.
