IMG 1010 - SIP Delayed Media Calls - Outbound
Overview:
Before software version 10.5.3, the IMG supports receiving incoming delayed media SIP calls where the incoming INVITE message does not contain an offer SDP. The IMG would then respond with a 200 OK message containing the offer SDP and negotiations would proceed after receiving ACK for INVITE with answer SDP. F-1666 gives the IMG the ability to generate the outbound delayed media SIP call where INVITE generated does not contain offer SDP. Negotiation will proceed once offer SDP is received from far end provisional response or in final response. The IMG will either pass, release, or cancel the call.
