IETF RFC 4103
RTP Payload for Text Conversation
|Publication Date:||1 June 2005|
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.
One payload format is described for transmitting text on a separate RTP session dedicated for the transmission of text.
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.
