Call from this number. abusive language then long hacking laugh.

This caller has called my office 3 times now using abusive and threatening language, to the point that it is scary.  I have his name, or at least the name whose phone line it is...Is there actually anything that can be done about this?  This guy scared me.

I just got a call from this # and the person just laughed... loud and long and rudely.  No other convo... *geeze*

Did not leave name
