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