This number is most likely a Medical Bill Collection Agency. They may work for other Companies but it is mostly affiliated with an Atlanta Area Hospital or Doctor.
This number called me, it only rang once. I called back & got a recorded message. The recording did not identify the company but they where asking me to enter the number that they tried to contact me on so I hung up. I think this is there way of weeding through a list of phone numbers to see which ones are active. if you give your number, you are on there updated list of good phone numbers, which will be used by them or sold to telemarketers.
