Got the same call.  no messege left.

Could hear phone picked up on other end AFTER my outgoing message completed and a male voice with an echo in the background said "Hello" a couple of times before hanging up.  Obviously didn't listen to see if a machine or a person answered.  Sounds like the intelligence level of a telemarketer.  Probably a roofing / flooring / painting contractor; this is their MO.

Received a call from this number.  I didn't answere and they didn't leave a message.

I got the same thing, so I kept calling back and hanging up on them!  Now they won't answer when I call!

We received a call from this number this morning, 5/13/2013.  The man said he was from the Fraternal Order of Police.  He was collecting money and pledges from people who wanted to help the families of fallen officers.  The caller ID said Stinson Beach California.  A google search identified the Fraternal Organization of Police as an organization based in Nashville, TN with a telephone number of 615.399.0900.
