Abstract
A communication system includes a packet-based data network and network elements coupled to the data network. The network elements are capable of participating in call sessions (e.g., Session Initiation Protocol or SIP call sessions) over the data network. A first network element can generate a call request including announcement information, with the call request targeted to one or more other network elements. The announcement information may include identification information (e.g., telephone number or web address) of the calling party and additional information that conveys to the called party some information relating to the desired call session (e.g., description of the content). Based on the announcement information, a called party may decide on disposition of the requested call.
