I just received the same thing - a hangup call. I did *69 to see who it was and it gave me 704-111-1000, along with the message that, if I wanted to call this number, press 1. I did so, and received the message "We're sorry, your call cannot be completed as dialed." If this is a political organization, it should be ILLEGAL!
I got 2 phone calls today from a704-111-1000. On my caller ID window
has Name Unavailable. I didn't try to call back. I don't answer phone
numbers I don't know.
