[PTT] My company has a scheme where "3333" on the internal network reaches
an internal emergency response centre who then direct the call externally if
required.  This was introduced to ensure that emergency vehicles are
directed to the right building and building entrance.  It might be
conceivable under such an arrangement to have a phone-context in the
original Request-URI.
