Actions Addressing Identified Issues with the Session Initiation Protocol's Non-INVITE Transaction
RFC 4320, “Actions Addressing Identified Issues with the Session Initiation Protocol's Non-INVITE Transaction”, is a Proposed Standard document published in January 2006 by R. Sparks. It updates RFC 3261. The canonical text is published by the RFC Editor.
Abstract
This document describes modifications to the Session Initiation Protocol (SIP) to address problems that have been identified with the SIP non-INVITE transaction. These modifications reduce the probability of messages losing the race condition inherent in the non-INVITE transaction and reduce useless network traffic. They also improve the robustness of SIP networks when elements stop responding. These changes update behavior defined in RFC 3261. [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.
