  Invalid mISDN PTMP redirecting signaling as TE towards NT.

  The mISDN PTMP redirection signaling (NOTIFY redirecting number and
  notification code, SETUP redirecting number) is also sent in PTMP/TE mode.
  It should only apply in PTMP/NT mode.  The call setup proceeds but the
  network (Deutsche Telekom) reacts with ugly ISDN STATUS messages.

  Also don't send the redirecting number ie when PTP is also sending the
  DivertingLegInformation2 facility.  The redirecting number ie is redundant
  and the network (Deutsche Telekom) complains about it.
