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.

One payload format is described for transmitting audio and text data within a single RTP session.

This RTP payload description recommends a method to include redundant text from already transmitted packets in order to reduce the risk of text loss caused by packet loss. This memo defines a Historic Document for the Internet community.
