My take is fairly simple.
Any caller/number that you are not familiar with, should be treated as a scam. There are too many operations trying to con people out of money and I don't believe it is worth taking a chance any more.
I am continually receiving calls from this number. It is Franklin County, Ohio's Correctional Facility 1 and I do not know the inmate who is attempting to call. There is an automated option to block the call, but every time I attempt it the call hangs up before I can confirm.
I tried calling the Franklin County Jail Administration Office at 614-525-5785, but their mailbox is full and no one has answered.
Hope this helps others who get calls from the number.
Thanks -- me too (for over a month now). Initially, the Caller ID was blocked, but for the past week or so I've been able to see the # (713-489-7846). This is a Houston, TX number (even though the correctional facility is in Columbus, OH).
Lately, a twist has been added: an initial recorded message from "(unintelligible name -- sounds like 'mah')" to accept the charges (followed by an offer to choose your payment method by pressing [0])
