This memo defines a new Media Feature Tag "real-time-text" for use in SIP registration and session establishment. This is used to indicate if a device capable of text communication has full real-time text capabilities or limitations in its capabilities requiring the users to apply some turn-taking habits. To the RFC editor Please replace y.y with the assigned ASN.1 identifier and XXXX with the RFC number of this specification.
