RTP Payload for DTMF Digits, Telephony Tones and Telephony Signals
Internet Engineering Task Force AVT WG INTERNET-DRAFT H. Schulzrinne/S. Petrack draft-ietf-avt-rfc2833bis-01.ps Columbia U./eDial October 21, 2002 Expires: March 2003 RTP Payload for DTMF Digits, Telephony Tones and Telephony Signals Status of this Memo This document is an Internet-Draft and is in full conformance with all provisions of Section 10 of RFC2026. Internet-Drafts are working documents of the Internet Engineering Task Force (IETF), its areas, and its working groups. Note that other groups may also distribute working documents as Internet-Drafts. Internet-Drafts are draft documents valid for a maximum of six months and may be updated, replaced, or obsoleted by other documents at any time. It is inappropriate to use Internet-Drafts as reference material or to cite them other than as “work in progress.” The list of current Internet-Drafts can be accessed at http://www.ietf.org/ietf/1id-abstracts.txt To view the list Internet-Draft Shadow Directories, see http://www.ietf.org/shadow.html. Copyright Notice Copyright (c) The Internet Society (2002). All Rights Reserved. Abstract This memo describes how to carry dual-tone multifrequency (DTMF) signaling, other tone signals and telephony events in RTP packets. This document updates RFC 2833. 1 Introduction This memo defines two payload formats, one for carrying dual-tone multifrequency (DTMF) digits, other line and trunk signals (Section 3), and a second one for general multi-frequency tones in RTP [1] packets (Section 4). Separate RTP payload formats are desirable since low-rate voice codecs cannot be guaranteed to reproduce these tone signals accurately enough for automatic recognition. -
