The Session Initiation Protocol (SIP) REFER extension as defined in
RFC 3515 automatically establishes a typically short-lived event
subscription used to notify the party sending a REFER request about
the receiver's status in executing the transaction requested by the
REFER.  These notifications are not needed in all cases.  This
specification provides a way to prevent the automatic establishment
of an event subscription and subsequent notifications using a new
SIP extension header field that may be included in a REFER request.
