Registering a SIP Resource Priority Header Field Namespace for Local Emergency Communications (RFC7135)
Original Publication Date: 2014-May-01

Internet Society Requests For Comment (RFCs)
This document creates the new Session Initiation Protocol (SIP) Resource Priority header (RPH) field namespace 'esnet' for local emergency usage and registers this namespace with IANA. The SIP Resource-Priority header field is defined in RFC 4412 [RFC4412]. The new 'esnet' namespace is to be used for inbound calls towards a public safety answering point (PSAP), between PSAPs, and between a PSAP and first responders or their organizations within managed IP networks. This namespace is not for use on the open public Internet because it can be trivially forged.
