Who called from 3012230109

Just did what was advised above. The ADA offers an opition to have your phone # removed from their list.  I wish other groups offered the same. Nice touch.

Have daily calls from ADA at 410-202-0108, 301-223-0109,703-291-9032,571-261-0106, 410-202-0108, 434-878-9983.  They never leave a message.  Very annoying.

the phone rings  when you answer it there is only silence on the other end of the line

when you call the number back  the phone rings once or twice then goes to a busy signal

I have been receiving calls ever 6hrs from this number. No message ever left. We are on the Do Not Call list. After reading these posts I learned that it is the American Diabetic Association. I called the number back, got a VM message that you can enter your number to be removed off their call list. They are calling to tell you about events going in your area. Hope this helps!
