The Session Initiation Protocol (SIP) allows for users to make
anonymous calls.  However, users receiving such calls have the right
to reject them because they are anonymous.  SIP has no way to
indicate to the caller that the reason for call rejection was that
the call was anonymous.  Such an indication is useful to allow the
call to be retried without anonymity.  This specification defines a
new SIP response code for this purpose.  [STANDARDS TRACK]
