The term Voiceband Data (or simply VBD) refers to the use of a suitable voiceband codec (commonly G.711u or G.711a) for the transport of data payloads using RTP as defined in RFC 3550 [RFC3550]. This document defines Media Gateway Control Protocol (MGCP) [RFC3435] packages that enable a Call Agent to authorize and monitor the transition of a connection to and from VBD with or without redundancy [RFC2198] and FEC (forward error correction) [RFC5109].

  Media Gateway Control Protocol (MGCP) Voiceband Data (VBD) Package and            General-Purpose Media Descriptor Parameter Package


   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.
