RFC 4508: Conveying Feature Tags with the Session Initiation Protocol (SIP) REFER Method

Still current, but amended. Parts of this document are changed or extended by RFC 8217. Read both.

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

The SIP "Caller Preferences" extension defined in RFC 3840 provides a mechanism that allows a SIP request to convey information relating to the originator's capabilities and preferences for handling of that request. The SIP REFER method defined in RFC 3515 provides a mechanism that allows one party to induce another to initiate a SIP request. This document extends the REFER method to use the mechanism of RFC 3840. By doing so, the originator of a REFER may inform the recipient as to the characteristics of the target that the induced request is expected to reach. [STANDARDS-TRACK]
