Who called from 6418475076

Came across as unknown so I didn't answer.  I don't have any reason for someone from Mason City Iowa to be calling me.

This number called the "soft phone" on my company's work computer. It did not leave a message.

Called after 8:30pm, leaving no message. Guess: political.

Hey! I was taking my afternoon snooze when these idiots called. No message, just dead air for a few seconds. Do I have to take the phone off the hook to not be bothered? Blocked, but this never ends. I hate whoever it is.

This # has called twice this afternoon on our land-line..irritating!
