Who called from 7177934025

Received twelve (12) phone calls from 717-793-4025 between the dates of 10/12/2011 thru 10/20/2011.  No message left on my answering machine, so I have no further information.
A web site described this number as coming from a collection agency.
Since no message was left, not sure why 12-calls within 8-days.
