Who called from 7315994498

Have been getting calls from (731)599-4498 about once a day for the last 4 days, they hang up when the voice mail starts, probably solicitors.

Have been getting calls from (731)599-4498 shows Union City, TN they hang up if we answer and they hang up on the answer machine. Looked it up and the personal look up says it is from a landline in Obion, TN that is run through Union City, TN some kind of Communication Company.

The same thing happened to us. I called them back and got no response, except "extension 401 isn't available," or some such.

Keep getting calls from this number. Caller ID says Union City, TN.  I called the number back and it said this extension is unavailable please leave a message. So I left an earful.  How do I stop this crap?

we  keep getting messages from 931-266-0482 and 615-349-2155 and 731-599-4498 and we don't know anyone in these places and they won't say anything when we do answer.
