i've been getting calls from this #, too; roughly 8 calls in the last 24hours. I haven't answered any of them as I normally don't if I don't recognize the # ... nevermind I don't know a soul in Ohio. They don't leave a message so I assume it's unimportant.
i called comcast and they said ti was their telemarketers. I told them that they are not allowed to call cell phones with telemarketing. they said they would make a note of my number; i told them i would contact the fcc.
