Sparks Internet-Draft dynamicsoft Expires: April 25, 2003 October 25, 2002 AVT Tones (RFC 2833) Interoperability Statement draft-sparks-avt-2833-interop-00 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. The list of Internet-Draft Shadow Directories can be accessed at http://www.ietf.org/shadow.html. This Internet-Draft will expire on April 25, 2003. Copyright Notice Copyright (C) The Internet Society (2002). All Rights Reserved. Abstract It is required to demonstrate interoperability of AVT Tones implementations in order to move that specification to draft standard. This memo outlines those features to be tested, as the first stage of an interoperability statement.

Introduction TBD - will borrow heavily from rtp-interop Use of 2198 to be tested separately 2. Features and Options Required to Demonstrate Interoperability 1. Demonstrate use of same sequence number and time-stamp base as remainder of audio stream 2. Demonstrate correct use of marker bit to indicate beginning of new event * Cisco Digium Pingtel Polycom 3. Demonstrate correct exchange of volume, duration, and end bit * Cisco Digium Pingtel Polycom 4. Demonstrate correct indication of supported named events via SDP * Cisco Pingtel 5. Interoperable exchange of data packets containing the required DTMF events * Cisco Polycom Digium - no ABCD 6. Events spanning more than one RTP packet * Polycom->Cisco * Cisco->Digium 7. Interoperable exchange of data packets containing the Flash event 8. Interoperable exchange of data packets containing Data Modem and Fax Events 9. Interoperable exchange of data packets containing Line Events 10. Interoperable exchange of data packets containing Extended Line Events 11.
