I received a call from this number on my cell phone.  When I tried to call it, I got a message that the number was not a working number.  My number is on the Federal No Call List, so I would like to know who was calling me.

The same number called me early this morning and had the same result when i called it back. Grrr.

Ditto!

got this call on my cell phone. tried to call it back i got a busy signal. GRRRR....

I am in Johnson City, Tennessee.  several internet resources say that this number is from Johnson City, so i called the local phone company.  The local phone company, Century Link, told me that this number is from East Tennessee State University Physicians and Associates.
