  • 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.

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.

  • On Common Channel Signaling Number 7 and Its Comparison with Multi-Frequency Coded Signaling and Internet Protocol
    International Journal of Electronics and Communication Engineering. ISSN 0974-2166 Volume 5, Number 2 (2012), pp. 125-132 © International Research Publication House http://www.irphouse.com On Common Channel Signaling Number 7 and its Comparison with Multi-Frequency Coded Signaling and Internet Protocol Md. Shah Alam1 and Md. Rezaul Huque Khan2 Dept. of Applied Physics, Electronics and Communication Engineering, University of Chittagong, Bangladesh 1 2 E-mail: [email protected], [email protected] Abstract A message based comparative study between signaling system #7(SS7) and R2 Signaling is done. The reasons for the transition from Multi-frequency Coded (MFC) Signaling to SS7 and SS7 to Internet Protocol are also discussed. Keywords: Common Channel Signaling No.7 (CCS7), R2 signaling or Multi- frequency Coded (MFC) signaling, Internet Protocol (IP), Advance Intelligent Network (AIN). Introduction The over increasing demand of telecommunication in the world wide significantly involves telecommunication signaling systems. The Common Channel Signaling no.7 is usually termed as Signaling System No.7 (SS7). The purpose of this paper is to study the signaling systems R2 or MFC, SS7 [1] and IP, to find the limitations of the above signaling system, analysis of the signaling systems (R2 and SS7) on the basis of their message format. An overall comparison between the two systems has been studied. This paper also focuses on the transition of MFC to SS7. A distinction is made between SS7 and IP and finally reasons are shown why SS7 is moving towards IP. Common Channel Signaling No. 7 Common Channel Signaling System No. 7 (i.e., SS7 or C7) is a global standard for telecommunications defined by the International Telecommunication Union (ITU) Telecommunication Standardization Sector (ITU-T).
