I love Caller ID and Google

So today the phone rang and it was a fax tone on the other end. Since I don't have a fax machine here, I was slightly annoyed and wondered who in the world is trying to fax me something. Five minutes later, the phone rang again -- it was the fax tone. I hung up, more annoyed. Five minutes later, again... So, from the Caller ID, I could see it was "Cornerstone Fel" and I knew the fax number. I looked up "Cornerstone 925-(rest of number)" in Google and quickly got their actual phone number, called them, and told them to stop faxing me since I have no idea who they are. The fact I could easily identify who was faxing me and get their actual contact information so quickly is amazing -- this is something that 5 years or so ago would have been a longer process to fix.
