The IESG has approved the following document:
- 'The Session Inititation Protocol (SIP) 'Replaces' Header '
<draft-ietf-sip-replaces-05.txt> as a Proposed Standard
This document is the product of the Session Initiation Protocol Working Group.
The IESG contact persons are Allison Mankin and Jon Peterson.
Technical Summary
This document defines a new header for use with SIP multi-party
applications and call control. The Replaces header is used to
logically replace an existing SIP dialog with a new SIP dialog. This
primitive can be used to enable a variety of features, for example:
"Attended Transfer" and "Call Pickup". Note that definition of these
example features is non-normative.
Security considerations for this Header include strong recommendation
of use of the Authenticated Identity Body and the Referred-by mechanism
use of it in authorization approaches.
Working Group Summary
The working group supported advancement of this document
because of strong support for the enabling of distributed
call control feature development.
Protocol Quality
The document was reviewed for the IESG by Allison Mankin and mid-course
security reviewing was provided by Eric Rescorla.
