    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)
