Received a call today around 4:00 pm ET from (402) 220-0375. It irks me when a call comes in and no message is left. Also, we are on the Do-Not-Call list so I assumed this was a telemarketer.
Two calls today from this number, no messages. I had a Comcast guy at my house this morning. Annoying, but mystery solved, anyway, thanks to this thread.
