I didn't answer because I no no-one in Tennessee, but when I called called back the recording said the office was closed.  It appears the an office of a charitable organization whose telephone number was spoofed.

I received a call from this number several times. I have no family or friends in Tennessee. If someone receives a call from this phone, I think it's fraud.

I just got a call from this number. I was on the phone with omeone importnant but didn't answer do to not knpwing any one from TN. I tried calling back and it wouldn't go through.

Got a call from this number, as we do not know anyone or any business in TN, we did not answer.  A google search provided this information http://lvbi.org/ProjectPaycheck3.html
However, I did not call back the number to find out if it was this organization calling or not, as we are not interested in making a contribution.
