Abstract

A system and method for correlating communication sessions. A globally unique correlation identifier is created and exchanged between the parties during Session Initiation Protocol (SIP) session setup to allow for association and correlation of additional SIP sessions between the same parties or with additional parties. The correlation information may then be used by network and session entities to perform different services.
