    abstract =  {This specification defines a new Session Initiation Protocol (SIP) P- Served-User header field parameter, "orig-cdiv-param", which defines the session case used by a proxy when handling an originating session after Call Diversion (CDIV) services has been invoked for the served user. The P-Served-User header field is defined in {[}RFC5502{]}. The P-Served-User header field conveys the identity of the served user and the session case that applies to this particular communication session and application invocation. This document updates {[}RFC5502{]} in order to add the originating after CDIV session case.},
