I had to answer because I was expecting a call from this area code. The usual dead air for 4-5 seconds - then sudden onset of background noise (like a boiler room) and someone asked for me by my first name. When he said he was a licensed contractor I hung up.
Looks like they maybe took the holidays off, since the last report was from early December. They called me twice over the last two days but seem to have been blocked by my blocking service and I've now blocked them with my provider.
