This video shows how annoying it is to receive spam calls special if you are in the middle of something. I just found out that using a reverse phone number service (like the one that http://www.mobilenumbr.com offers) I can actually get information about the number. For example if I received a call from 423-201-0011 I will query it's details using www.mobilenumbr.com then I can have the name of the owner, the location, the email address and even the social network accounts if there's any.
