Received another call from this number, but it was blocked by my Digitone call blocker.  Caller ID showed Out of Area.  If it is TxFOP, they will not give up.  They are relentless and have several different numbers that they use.  They are the main reason I bought and installed a call blocker.  We made the mistake of donating once about ten years ago thinking they were a worthwhile charity.  While the cause is worthwhile, not much of the cash actually gets to the policemen and policewomen killed or injured in the line of duty, or their families. That, at least, according to my research on Texas fraternal orders of police.
