I got a call from this number as well....I called back and it said the number is out of service...upon looking further into it I found out that it is a soliciation company for many different companies.

I received two calls from this number.  I answered the first, but nobody said anything.  I called back and was told that the number was not in service.

The second time I answered the person said he was calling me from the IT department of PC Doctor, and asked me if I had a computer.

They call and left no message.  To me I'd go along with the phishing idea.

Got a call from the number asking "to speak to the home owner please" I hung up.

Got a hang up message from this number. When I tried to call it back it said the number was not in service.

As soon as I cleared my list of blocked numbers, these annoying calls started flooding in again.  Tiresome in the extreme, and no way to counteract as a call back gets only a horrible screeching fax-sound on the line.
