RFC 4244: An Extension to the Session Initiation Protocol (SIP) for Request History Information

This RFC has been replaced. Do not implement against it for new work — it was formally obsoleted by RFC 7044.

Current version: RFC 7044 — An Extension to the Session Initiation Protocol (SIP) for Request History Information

In plain English — editorial summary, not part of the RFC

This document defines a standard mechanism for capturing the history information associated with a Session Initiation Protocol (SIP) request. This capability enables many enhanced services by providing the information as to how and why a call arrives at a specific application or user. This document defines a new optional SIP header, History-Info, for capturing the history information in requests. [STANDARDS-TRACK]
