Title : The requirement for direct transcoding with Session
Initiation Protocol
Author(s) : T. Kang, et al.
Filename : draft-kang-sipping-dtransc-requirement-00.txt
Pages : 11
Date : 2005-6-8
This document presents a set of Session Initiation Protocol (SIP)
call control requirements that support communication with direct
transcoding capability. Several solutions are addressed for
transcoding service.
Direct transcoding requires two kinds of requirements: the service
requirement and call control requirement. Service requirement is no
constraint of codec adaptation and interoperability of models. Call
control requirement is exchange of codec information and minimizing
of call set up delay.
The model might be applied to general-purpose services satisfying the
requirements of multimedia applications without an additional INVITE.

NOTE: The mail server at ietf.org can return the document in
MIME-encoded form by using the "mpack" utility. To use this
feature, insert the command "ENCODING mime" before the "FILE"
command. To decode the response(s), you will need "munpack" or
a MIME-compliant mail reader. Different MIME-compliant mail readers
exhibit different behavior, especially when dealing with
"multipart" MIME messages (i.e. documents which have been split
up into multiple messages), so check your local documentation on
how to manipulate these messages.
Below is the data which will enable a MIME compliant mail reader
implementation to automatically retrieve the ASCII version of the
