I use my phone for business and I frequently get calls from customers or potential customers who are not yet in my contact data base. Since most of my work is with the government, all that normally shows on caller ID is the phone number.
Received a call from this number at 7:49am PST today, 1.16.12. Missed the call and no message was left. When I attempted to return the call (to see who was calling me), I heard a recorded message saying the number had been disconnected or is no longer in service.
