Definition of Events for Channel-Oriented Telephony Signalling

Overview

RFC 5244, “Definition of Events for Channel-Oriented Telephony Signalling”, is a Proposed Standard document published in June 2008 by H. Schulzrinne, T. Taylor. It updates RFC 4733. The canonical text is published by the RFC Editor.

Abstract

This memo updates RFC 4733 to add event codes for telephony signals used for channel-associated signalling when carried in the telephony event RTP payload. It supersedes and adds to the original assignment of event codes for this purpose in Section 3.14 of RFC 2833. As documented in Appendix A of RFC 4733, some of the RFC 2833 events have been deprecated because their specification was ambiguous, erroneous, or redundant. In fact, the degree of change from Section 3.14 of RFC 2833 is such that implementations of the present document will be fully backward compatible with RFC 2833 implementations only in the case of full ABCD-bit signalling. This document expands and improves the coverage of signalling systems compared to RFC 2833. [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.
