This is one of a multitude of numbers used by an outfit called Dytel, Inc. They have hundreds of pseudo-charity scams running, all from unidentifiable numbers in Alabama. If you report this to the DNC list, make sure you list it as Dytel, Inc.
Charity solicitation scam...usually for something related to law enforcement. I have received dozens of calls with caller ID 'Alabama' from a series of different numbers. If you try to call the number back, you are immediately sent to voicemail which says that the mail box is full.
