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]
