Re-INVITE and Target-Refresh Request Handling in the Session Initiation Protocol
RFC 6141, “Re-INVITE and Target-Refresh Request Handling in the Session Initiation Protocol”, is a Proposed Standard document published in March 2011 by G. Camarillo, C. Holmberg, Y. Gao. It updates RFC 3261. The canonical text is published by the RFC Editor.
Abstract
The procedures for handling SIP re-INVITEs are described in RFC 3261. Implementation and deployment experience has uncovered a number of issues with the original documentation, and this document provides additional procedures that update the original specification to address those issues. In particular, this document defines in which situations a UAS (User Agent Server) should generate a success response and in which situations a UAS should generate an error response to a re-INVITE. Additionally, this document defines further details of procedures related to target-refresh requests. [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.
