I wanted to prank call my friends using funny sound effects after listening to a prank call show where the host plays them at their victims. I also wanted to try out Ruby, so I decided to create a prank calling application as my first project.<p>Its called InmateBridge, after one of the included sound effects.<p>The application is in essence Asterisk PBX, Asterisk Statis application (the Ruby part), and sound effects in a container for easy deployment.<p>You give it SIP trunk credentials to call out to victims with and connect to the bridge using IAX2 yourself. While making calls you operate the soundboard on the console UI.<p>You can also bring your own sound effects.
