My dad got a call from this number (972-702-7704), but didn't answer. He has a lot of doctors, so he called back, thinking it might be one of them. All he got was a message saying the either it was not a working number or needed to be dialed with a prefix. No idea who it is, except that it's a Dallas area code.

Received a call from this phone number and I have no idea who it is, so I didn't answer it.
