Technical Summary This document defines a framework for transcoding with SIP. This framework includes how to discover the need of transcoding services in a session and how to invoke those transcoding services. Two models for transcoding services invocation are discussed: the conference bridge model and the third party call control model. Both models meet the requirements for SIP regarding transcoding services invocation to support deaf, hard of hearing, and speech-impaired individuals. Working Group Summary The SIPPING WG supports the advancement of this document. Protocol Quality This document was reviewed for the IESG by Jon Peterson.
