Abstract
This document presents a set of Session Initiation Protocol
(SIP) user requirements that support communications for deaf, hard of
hearing and speech-impaired individuals. These user requirements
address the current difficulties of deaf, hard of hearing and
speech-impaired individuals in using communications facilities, while
acknowledging the multi-functional potential of SIP-based
communications.
A number of issues related to these user requirements are further
raised in this document.
Also included are some real world scenarios and some technical
requirements to show the robustness of these requirements on a
concept-level.
