Who called from 5162778421

Received a call but no one answers and hear a beep in the background.

I called it back and it was a recording saying it was "donor services" a non profit charity organization.

This New York call came to Kansas at 19:37 hours (illegal) on 6-22-09. Call not answered and no message left. The caller ID said: "Mthers Ag Dr Dr". I think we could probably make the leap of faith that this is Mothers Against Drunk Driving.

Received a call from 516-277-8421, called ID showed Animal League.  Did not leave a message.

Keep getting calls from this number.  If you answer, there is no one at the other end, so I hang up.  If I don't answer, they don't leave a message.  Very annoying.  I work nights, and they always call when I am sleeping.
