Technical Summary This document introduces the transport of call control related User to User Information (UUI) using the Session Initiation Protocol (SIP), and develops several requirements for a new SIP mechanism. Some SIP sessions are established by or related to a non-SIP application. This application may have information that needs to be transported between the SIP User Agents during session establishment. In addition to interworking with the ISDN UUI Service, this extension will also be used for native SIP endpoints requiring application UUI. Working Group Summary The working group consensus on this document is solid. Two WGLCs were held to ensure that all comments and feedback were accounted for. Document Quality This is a requirement document, as such there aren't any implementation details to list. That said, the document has received a positive nod from major service provider and equipment vendors. Personnel Vijay Gurbani is the document's shepherd. Gonzalo Camarillo is the responsible AD.
