Conference Factory

An IMS (IP Multimedia Subsystem) user agent that wants to create a conference forwards a SIP (Session Initiation Protocol) INVITE request towards the S-CSCF (Serving – Call Session Control Function) which acts as the conference-factory URI (Uniform Resource Indicator). This means it coordinates the establishment of a conference and will supply the actual conference URI to the user once it has been generated. In doing so, the services of the MRFC may be employed.
