Who called from 4127738561

Got a call from this number twice last night at 7:57. The 1st time all  I heard was music..then silence,music again,then silence..after a while it disconnected. Then around a half hour later,they called again asking for my dad and said they were an organization that he supported. Said they would try too call the following day.

I have received calls from this number over the last 3 weeks almost nightly. I have not answered.
According to:
http://www.intelius.com/results.php?ReportType=33&
it is a land line in Pittsburgh.  ???
I may answer next time to try and find out.

Outreach associates?  No idea who they are but they call pretty frequently and never leave a message and we never bother to answer.

Silent call.  I hung up after my second "hello".

During the last five hours this company(Outreach Assoc has called more than three times.  During a given day they call more than five times.  This is very annoying.
