- [build](Makefile) Now use alpine:3.20 (asterisk:20.9.3). - [asterisk](src/asterisk/config/modules.conf) Add modules that are not loaded by default helping to get rid of error messages during startup. - [asterisk](src/asterisk/config/console.conf) Add `console.conf` so we can use `chan_console.so` since `chan_alsa.so` will be removed in asterisk:21. - [demo](demo/Makefile) Now use `chan_console.so` since `chan_alsa.so` will be removed in asterisk:21.
