IESG note | IESG Note This document is being published for the information of the community. It describes a non-IETF protocol that is currently being deployed in a number of products. Implementers should be aware of RFC 3015, which was developed in the IETF Megaco Working Group and the ITU-T SG16 and which is considered by the IETF and ITU-T to be the standards-based (including reviewed security considerations) way to meet the needs that MGCP was designed to address. The IETF Megaco working group and the ITU-T Study Group 16 are developing extensions to RFC 3015 for functions of the type addressed in this document. | ||

IESG Note This document is being published for the information of the community. It describes a non-IETF protocol that is currently being deployed in a number of products. Implementers should be aware of RFC 3525 [37], which was developed in the IETF Megaco Working Group and the ITU-T SG16, and is considered by the IETF and ITU-T to be the standards-based (including reviewed security considerations) way to meet the needs that MGCP was designed to address. The IETF Megaco Working Group and the ITU-T Study Group 16 are developing extensions to RFC 3525 [37] that for functions of the type in addressed in this document. Abstract This document provides a basic set of Media Gateway Control Protocol (MGCP) packages. The generic, line, trunk, handset, RTP, DTMF (Dual Tone Multifrequency), announcement server and script packages are updates of packages from RFC 2705 with additional explanation and in some cases new versions of these packages. In addition to these, five new packages are defined here. These are the signal list, resource reservation, media format, supplementary services and digit map extension packages.
