Internet Engineering Task Force (IETF) J. Stone Request for Comments: 6498 R. Kumar Category: Informational F. Andreasen ISSN: 2070-1721 Cisco Systems February 2012 Media Gateway Control Protocol (MGCP) Voiceband Data (VBD) Package and General-Purpose Media Descriptor Parameter Package Abstract This document defines Media Gateway Control Protocol (MGCP) packages that enable a Call Agent to authorize and monitor the transition of a connection to and from Voiceband Data (VBD) with or without redundancy and FEC (forward error correction). Although the focus is on VBD, the General-Purpose Media Descriptor Parameter package can be used to authorize other modes of operation, not relevant to VBD, for a particular codec. In addition to defining these new packages, this document describes the use of the Media Format Parameter package and Fax package with VBD, redundancy, and FEC.
