I’ve had my Raspberry Pi and Asterisk setup running now for nearly 2 months. It hasn’t failed me once in this time.
If you remember back I ended up installing Raspbian and configuring Asterisk manually from command line. This setup suits me, as I want to learn about how it all works, not learn how to use one of the dedicated images that has a fancy web GUI (and learn how to use that). I might end up changing to that type of setup eventually, however what i have now works with all the features I need.
Will be sure to post back as time progresses with this setup.
