Who called from 2132322384

Called the number back and it says "You have reached the Doctors Group" and gives instructions on how to be added to their do not call list.

I live in the Dallas area and have recieved one call from this number.  I did not answer but my caller ID displayed "Doctors Group."

I just got a phone call from the "Dr. Group" at 9:04am this morning. Why do they call us, I hate calls that don't leave voicemails.

I never know this is at all!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

Received  a call from this number. Caller ID indicated "Doctors Group". I did not answer and they left no message. We are getting calls from the "Doctors Group" every day. The most alarming thing is they come from a different number nearly every time! Here is a list of numbers they've called from in the last 2 weeks:
