I received calls from this number as well as many other local numbers and they're all the same - they don't leave a message and when called back, a recording says the number is no longer in service. Whoever is calling is spoofing out-of-service numbers. And they're so dumb they don't even leave a message. There must be someone they can be reported to as I'm sure it's illegal to spoof numbers that are not yours, but I don't know to whom they should be reported.

Jeff Brown, calls every day, all throughout the day. Never leaves a message. Scammer. I'll never pick up.

Calls all the time. Several times a day. Never leaves a message. This needs to stop. I work the graveyard shift and this idiot keeps waking me up.

Probably time to buy a call blocker device, app, or phone.
Google "call blocker" to see the various types, and find one that best meets your needs.

Got a call from "Jeff Brown" a few minutes ago... didn't pickup and he left no message.
