Title
Extending the Session Initiation Protocol (SIP) Reason Header for Preemption Events

Applicability

This document proposes an IANA Registration extension to the Session Initiation Protocol (SIP) Reason Header to be included in a BYE Method Request as a result of a session preemption event, either at a user agent (UA), or somewhere in the network involving a reservation-based protocol such as the Resource ReSerVation Protocol (RSVP) or Next Steps in Signaling (NSIS). This document does not attempt to address routers failing in the packet path; instead, it addresses a deliberate tear down of a flow between UAs, and informs the terminated UA(s) with an indication of what occurred.
