This document describes some specifics that apply when Signaling
Compression (SigComp) is applied to the Session Initiation Protocol
(SIP), such as default minimum values of SigComp parameters,
compartment and state management, and a few issues on SigComp over
TCP. Any implementation of SigComp for use with SIP must conform to
this document, in addition to SigComp and support of the SIP and
Session Description Protocol (SDP) static dictionary.
Working Group Summary
This document has been in the workings for several years, and it has
been given the time needed to make it mature. The document has
been carefully reviewed by both the WG and various other SIP and
SigComp experts, and there is WG consensus that the document
should now be published as an RFC.
There are several independent implementers of SigComp, and they
have collectively developed the content of this specification, based
on running code experience.
Document Sheperd for this document is Lars-Erik Jonsson, and Magnus
Westerlund is the Responsible Area Director.
