	Title           : Call Completion for Session Initiation Protocol (SIP)

The features "call completion on busy subscriber" and "call
completion on no reply" allow the calling party of a failed call to
be notified when the called party becomes available to receive a
call.  This document describes an architecture for implementing these
features in the Session Initiation Protocol: "Call completion"
implementations at the caller's and callee's endpoints cooperate to
place the caller's request for call completion into a queue at the
callee's endpoint, and, when a caller's request is ready to be
serviced, re-attempt the original, failed call.
