Overview

RFC 3891, “The Session Initiation Protocol "Replaces" Header”, is a Proposed Standard document published in September 2004 by R. Mahy, B. Biggs, R. Dean. The canonical text is published by the RFC Editor.

Abstract

This document defines a new header for use with Session Initiation Protocol (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 the definition of these example features is non-normative. [STANDARDS-TRACK]
