The present document gives examples of signalling flows for the the IP multimedia call control based on SIP and SDP.
These signalling flows demonstrate the interaction with the IP-connectivity network (GPRS), and with the protocol provided at the Cx interface.
These signalling flows provide detailed signalling flows, which expand on the overview information flows provided in 3GPP TS 23.228 [2].
