Communications Resource Priority for the Session Initiation Protocol
RFC 4412, “Communications Resource Priority for the Session Initiation Protocol”, is a Proposed Standard document published in February 2006 by H. Schulzrinne, J. Polk. It has since been updated by RFC 7134. The canonical text is published by the RFC Editor.
Abstract
This document defines two new Session Initiation Protocol (SIP) header fields for communicating resource priority, namely, "Resource-Priority" and "Accept-Resource-Priority". The "Resource-Priority" header field can influence the behavior of SIP user agents (such as telephone gateways and IP telephones) and SIP proxies. It does not directly influence the forwarding behavior of IP routers. [STANDARDS-TRACK]
What “Proposed Standard” means
An entry-level standards-track specification: stable, peer-reviewed and a solid basis for implementation, though it may still evolve before becoming an Internet Standard.
