My CID says it is from the DFA. I believe, but cannot be absolutely certain, that this is Democracy For America, Howard Dean's political organization. I never pick up and they never leave a message, so we may never know for sure.
This phone call is from Organizing For Action. I guess a political group. I called the number and you get a message from a fund raising organization on behalf of OFA. I held on it rang and connected me to a person and I asked for them to never call me again. He asked for my number, I gave it to him, he said my name, and I said yes, and said he would remove me from the list. Simple, but we'll see.
