Just got a call from this one. Caller ID just had the 7-digit number, and said "Texas." I picked it up, and it rang one more time (like the ringing you hear when you call someone, but I received this call) then hung up. I called it back and got a recording saying "This number is not in service, this is a recording." Strange getting a call from a number which isn't in service.

Got a call from this number too, and they just hung up. they're probably doing some creditation.
