Received a phone call at 3:30 AM - no one answers. Called number and we get a recorded message "this the verzion network, all circuits are busy, try your call again later" or just a busy signal (maybe recording also). I do not know anyone with this number. is this a prank call.

Received a call from this number at 1:30 am but didn't pick up in time. No message was left so I called the number several times but all I kept getting was a busy signal.

Receiving calls from 404-253-7920 coming into company switchboard. Number emits fax tone in operators ear.

Received a call from this number: (404) 253-7920 The caller ID said " Norfolk Southern". According to the info on the search, it appears to be a railroad company. Have no idea why they would be calling me, unless the number has been spoofed.

This is in fact Norfolk Southern Railroad.  EDI department.
