摘要： Subscribers of an enhanced communication system are enabled to indicate invocation or clearing of media specific features such as music-on-hold or video-on-hold. The invocation or clearing is transmitted to participating end points as a Session Initiation Protocol (SIP) re-INVITE message with Session Description Protocol (SDP) attribute descriptions identifying the feature, applicable media channels and whether the message is for invocation or clearing of the feature.
