Calling me collect indicating it is the State Police

Caller called multiple times 4:37am, 4:43am, 7:56am .
I did not answer the first two, but I did answer at 7:56. It was a man speaking an unfamiliar language. He almost sounded like it was not a phone call but a conference line. Lots of background noise. I thought it was very strange. I kept saying "Hello,Hello" and then I told the person we had a bad connection and then he mumbled something and hung up.

called back # and received diconnect notice

I did not recognize the number so I googled it and found this site.

I recieved a call from this number as well, a man spoke in Arabic and English, I hung up on him.  I am wondering if this is a disposable number?
