Caller Preferences for the Session Initiation Protocol
RFC 3841, “Caller Preferences for the Session Initiation Protocol”, is a Proposed Standard document published in August 2004 by J. Rosenberg, H. Schulzrinne, P. Kyzivat. The canonical text is published by the RFC Editor.
Abstract
This document describes a set of extensions to the Session Initiation Protocol (SIP) which allow a caller to express preferences about request handling in servers. These preferences include the ability to select which Uniform Resource Identifiers (URI) a request gets routed to, and to specify certain request handling directives in proxies and redirect servers. It does so by defining three new request header fields, Accept-Contact, Reject-Contact, and Request-Disposition, which specify the caller's preferences. [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.
