Receive several calls a week from this number, they always hang up. Finally called comcast to ask if that was an actual comcast number - they said no; I could block it, and would not be missing any calls from Comcast. (since they are my actual cable/tv provider)
Called 12.17.14 after 7PM (I do not answer unrecognizable phone numbers after 5PM) and since I did not answer, the caller hung up without leaving a message. I assume it is either a SCAM or SPAM!!!
