The IESG has approved the following document: - 'Media Gateway Control Protocol Fax Package ' <draft-andreasen-mgcp-fax-08.txt> as an Informational RFC This document has been reviewed in the IETF but is not the product of an IETF Working Group. The IESG contact person is Cullen Jennings. A URL of this Internet-Draft is: http://www.ietf.org/internet-drafts/draft-andreasen-mgcp-fax-08.txt Technical Summary This document defines a Media Gateway Control Protocol (MGCP) package to support fax calls. The package allows for fax calls to be supported in two different ways. The first one utilizes ITU-T Recommendation T.38 for fax relay under the control of the Call Agent. The second one lets the gateway decide upon a method for fax transmission as well as handle the details of the fax call without Call Agent involvement. Working Group Summary Not WG Document. Document Quality Joe Stone provided expert review. Personnel Cullen Jennings is AD for this document. RFC Editor Note Please change all occurrences of "whatever.net" to "example.net" Section 2.5.2 OLD The attribute "T38MaxBitRate" is incorrectly registered with IANA as NEW The attribute "T38MaxBitRate" was once incorrectly registered with IANA as Section 2.1.2, 1st paragraph OLD: However, in order to use any special fax handling, support for it MUST be negotiated with the other side by passing and recognizing relevant parameters via the LocalConnectionDescriptor and RemoteConnectionDescriptor. NEW: However, in order to use any special fax handling, support for it MUST be negotiated with the other side by passing and recognizing relevant parameters via the LocalConnectionDescriptor and RemoteConnectionDescriptor (this includes the use of RTP-based T.38). ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ Section 2.1.3, 1st paragraph OLD: However, the gateway may still adjust local echo cancellation and/or switch to an alternative codec as needed (in particular, this does not preclude the use of RTP-based T.38). ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ NEW: However, the gateway may still adjust local echo cancellation and/or switch to an alternative codec as needed. Section 6, beginning: ADD: Changes since -08 * RTP-based T.38 disassociated with the Off procedure and re-associated with the Gateway procedure.
