The document discusses common myths about using the Asterisk communications platform for business critical applications. It debunks myths such as: Asterisk only being suitable for hobbyists; requiring Linux expertise; inability to scale or provide high availability. Real world case studies are presented of large organizations using Asterisk successfully for tens of thousands of users and high call volumes. The document promotes Asterisk as a full-featured and mainstream solution when configured properly using techniques like redundant servers and SIP proxies.
