      Asterisk is getting a "No D-channels available!" warning message every 4 seconds.
      
      Asterisk is just whining too much with this message: "No D-channels
      available!  Using Primary channel XXX as D-channel anyway!".
      
      Filtered the message so it only comes out once if there is no D channel
      available without an intervening D channel available period.
      
      (closes issue #17270)
