    In chan_misdn, the DivertingLegInformation2 DivertingNr is garbage when the number is restricted.
  
    The same thing happens with DivertingLegInformation1 DivertedTo number.
  
    The misdn_PresentedNumberUnscreened_extract() extracted the Unscreened
    PartyNumber field unconditionally.  It now checks the presented number
    unscreened type to see if the PartyNumber was even present.
