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.
