This document defines the REFER method.  This Session Initiation
Protocol (SIP) extension requests that the recipient REFER to a
resource provided in the request.  It provides a mechanism allowing
the party sending the REFER to be notified of the outcome of the
referenced request.  This can be used to enable many applications,
including call transfer.

In addition to the REFER method, this document defines the the refer
event package and the Refer-To request header.

This document is a product of the Session Initiation Protocol Working
Group of the IETF.

This is now a Proposed Standard Protocol.
