The IESG has approved the following document:
- 'RTP Payload for Text Conversation '
<draft-ietf-avt-rfc2793bis-09.txt> as a Proposed Standard
This document is the product of the Audio/Video Transport Working Group.
The IESG contact persons are Allison Mankin and Jon Peterson.
Technical Summary
This specification describes how to carry real time text conversation
session contents in RTP packets. Text conversation session contents
are specified in ITU-T Recommendation T.140.
One payload format is described for transmitting text on a separate
RTP session dedicated for the transmission of text.
This RTP payload description also recommends a method to include
redundant text from already transmitted packets in order to reduce
the risk of text loss caused by packet loss. It uses the payload format
format specified in RFC 2198, and updated in draft-ietf-avt-text-red, in
current IETF review.
The document obsoletes RFC 2793. The text clarifies
ambiguities in RFC 2793, improves on the specific implementation
requirements learned through development experience, and gives
explicit usage examples.
Working Group Summary
The material in this document was strongly supported by the AVT
working group. There has been considerable IETF review of the
text/red media type; in this document, the RTP domain usage is clearly
indicated, as was carefully discussed as the context for that text mediatype.
Protocol Quality
The document was reviewed for the IESG by Allison Mankin and the AVT
Working Group chairs.

Abstract
OLD:
This memo describes how to carry real time text conversation
session contents in RTP packets. Text conversation session contents
are specified in ITU-T Recommendation T.140.
NEW:
This memo obsoletes RFC 2793; it describes how to carry real time text
conversation session contents in RTP packets. Text conversation session
contents are specified in ITU-T Recommendation T.140.
IANA Considerations
OLD:
This document defines one RTP payload format named "t140" and an
associated MIME type "text/t140", to be registered by IANA.
NEW:
This document updates the RTP payload format named "t140" and the
associated MIME type "text/t140", in the IANA RTP and Media Type registries.
