# Asterisk and FreePBX 15 are installed! Go to the web interface at http://YOUR-IP to finish setup.

Asterisk 17 is EOL; don't use it. If you want a version other than Asterisk 16, which is packaged with Debian (both Buster and Bullseye), you'll have to build from source. I don't plan on making any more changes to this script; I'm working on Debian 11 (Bullseye) and the soon-to-be-released FreePBX 16 now. https://gist.github.com/billsimon/f66636f83de8e1162ea318ccd7a9b576
