Who called from 2136290000

Received call from this number 11-01-10; partial message left on my voice mail regarding "Wall Street Bandits" and voting for Ted Strickland.

"Grandma, I'm in financial difiiculty, can you help? " When my mother responded, she said "Oh, ****, Grandma doesn't have a job anymore"  and they hung up.  She thought the call was from her grandson.  She has trouble hearing on the phone, but knew it was a male voice and she only has one grandson.

just got a call from this number has anyone figured out where it is coming from and if it is some sort of scam

When call came up blocked local police department tracked back trap results from phone carrier to Park 5th at the time.

Called, left 3x voicemails that were a half-second long electronic-like buzz.  Very annoying
