IP video telephony with text component, IP Text Telephony, IP Total
Conversation, IP Mobiles with text etc. can now be accomplished in a
standardised way.

The specification on how to transmit text for real time chatting in IP
networks is now published as RFC 2793 from IETF. (It was approved in
February, but got published with its number now.)

With it comes a new registered MIME type "text/t140" so that it can be
specified for example in the multimedia protocol SIP.

The multimedia protocol ITU-T H.323 is already ready for text addition with
its Annex G, referencing to RFC 2793.

Thanks to all who have contributed, and good luck to all who now creates
interworking Total Conversation solutions with this component!

This memo describes how to carry text conversation session contents
in RTP packets. Text conversation session contents are specified in
ITU-T Recommendation T.140 [1].

Text conversation is used alone or in connection to other
conversational facilities such as video and voice, to form multimedia
conversation services.

This RTP payload description contains an optional possibility to
include redundant text from already transmitted packets in order to
reduce the risk of text loss caused by packet loss. The redundancy
coding follows RFC 2198.

This document is a product of the Audio/Video Transport Working Group
of the IETF.

This is now a Proposed Standard Protocol.

This document specifies an Internet standards track protocol for
the Internet community, and requests discussion and suggestions
for improvements.  Please refer to the current edition of the
"Internet Official Protocol Standards" (STD 1) for the
standardization state and status of this protocol.  Distribution
of this memo is unlimited.

This announcement is sent to the IETF list and the RFC-DIST list.
Requests to be added to or deleted from the IETF distribution list
should be sent to IETF-REQUEST at IETF.ORG.  Requests to be
