Its name comes from the asterisk symbol, *. Source: Wikipedia Asterisk is like a box of Legos for people who want to create communications applications. It includes all the building blocks needed to create a PBX, an IVR system, a conference bridge and virtually any other communications app you can imagine. Source: Official Asterix Website
