As described in Feature F-5230, the H.223 and H.245 protocols are used between multimedia endpoints over a circuit switched network. These protocols are utilized after a successful call between two endpoints that indicates the call is for multimedia. Feature F-5698 gives the IMG the ability to detect an incoming SS7/ISDN multimedia call based on a specific octet contained in the SS7/ISDN setup message. If the call is considered an audio call, the message will be interworked as a normal ISDN/SS7 to SIP call. If however, the call is considered a multimedia call, a proprietary SIP Header can be added indicating it is a multimedia call and the added header will be interworked to the SIP side. The feature is enabled through a new header added to the SIP Headers object. Refer to the information below.
