Note: There is an additional file storage area at ftp://standards.nortelnetworks.com/megaco/docs/ There is a Web interface (up to February 2001 only): http://standards.nortelnetworks.com/archives/megaco.html The Megaco media gateway control protocol, RFC 3015 (also published as ITU-T Recommendation H.248), was developed by the Megaco Working Group in close cooperation with ITU-T Study Group 16. The protocol responds to the requirements documented in RFC 2805. The Megaco Working Group has identified a large number of corrections to the protocol specification in the year and a half since RFC 3015/Rec. H.248 was approved. As guardians of the protocol specification, Study Group 16 maintains a record of these corrections in the form of an "Implementor's Guide". Study Group 16 now proposes to issue a new version of Recommendation H.248 incorporating these corrections and a limited number of new protocol features. The current charter includes one package, on naming patterns. If the WG determines that other packages are of general usefulness, an AD and IESG review is needed to permit addition of the package to the charter. The basic mandate of the Megaco Working Group is to cooperate with the ITU-T in the continuing refinement and evolution of the Megaco/H.248 protocol. This specifically includes participation in the development of H.248v2 and subsequent versions, creation of packages of general usefulness to users of the protocol, and creation of documents providing additional information to the development community on specific aspects of the protocol. The work of package development for specific applications is specifically excluded from the Working Group's mandate. However, the Megaco list will continue to be a place where such packages can be discussed and refined before being submitted to the IESG for potential publication as individually-submitted RFCs.
