Session Initiation Protocol Extension Header Field for Service Route Discovery During Registration
RFC 3608, “Session Initiation Protocol Extension Header Field for Service Route Discovery During Registration”, is a Proposed Standard document published in October 2003 by D. Willis, B. Hoeneisen. It has since been updated by RFC 5630. The canonical text is published by the RFC Editor.
Abstract
This document defines a Session Initiation Protocol (SIP) extension header field used in conjunction with responses to REGISTER requests to provide a mechanism by which a registrar may inform a registering user agent (UA) of a service route that the UA may use to request outbound services from the registrar's domain.
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.
