I received a call from this number stating it was a federal prison. Can I block this number?

I have rece'd 3 messages from this number at my work, which did not want my voice mail and stated they would call my cell, but no messages on that. Do not know who they are....

Two calls today from 8-628-245-2253.  Didn't answer either one.  Have no idea who it is.

I don't know if this is the number or not, since all I get is "Unavailable." My phone service is not supposed to allow anonymous callers through, so I'm not sure why it's being allowed--I'll have to call them, I guess. But in the meantime I'll enter into my phone itself this number that spells "Unavailable" without the U, to go along with my entry of "Unavailable" without the E. Sigh. I just wish "Do Not Call" and call-blocking from my service worked!

I have recieved phone calls from this number everyday at the same time.  I don't answer the call but when I recall the number my cell phone service says it is an international call.

8-628-245-2253 keeps calling me looking for a Wanda Otis.  I have never met this person (if they exist).  They never identify themselves or state their business.

I have IOBI on my phone which lets me block certain callers. When i right clicked on this number that comes up " unavailable", it said (nav)ail-able
I then looked to see what number went with the letters and came up with this area code etc.
I recieved 11 calls from 11:15 a/m to 2:26 p/m.
