CALL CONTEXT CONVEYANCE

摘要

A communication system, method, and components are described. Specifically, a communication system having the ability to carry a transitive context and communicate the transitive context to new participant user agents for continuity through all related call dialogs is disclosed. The transitive context communication is possible through the use of a newly created SIP dialog using a REFER message and/or an INVITE message for all call flows and topology change operations.
