Configuration directories
How do I get the configuration directories from FreeSWITCH again?
Nick vs Networking shows a command for getting all _dir
paths:
$ fs_cli -x "global_getvar" | grep _dir base_dir=/nix/store/xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx-freeswitch-1.xx.x recordings_dir=/var/lib/freeswitch/recordings sounds_dir=/etc/freeswitch/sounds conf_dir=/etc/freeswitch log_dir=/var/log/freeswitch run_dir=/run/freeswitch db_dir=/var/cache/freeswitch mod_dir=/nix/store/xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx-freeswitch-1.xx.x/lib/freeswitch/mod htdocs_dir=/nix/store/xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx-freeswitch-1.xx.x/share/freeswitch/htdocs script_dir=/nix/store/xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx-freeswitch-1.xx.x/share/freeswitch/scripts temp_dir=/tmp grammar_dir=/nix/store/xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx-freeswitch-1.xx.x/share/freeswitch/grammar fonts_dir=/nix/store/xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx-freeswitch-1.xx.x/share/freeswitch/fonts images_dir=/nix/store/xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx-freeswitch-1.xx.x/var/lib/freeswitch/images certs_dir=/nix/store/xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx-freeswitch-1.xx.x/etc/freeswitch/tls storage_dir=/var/lib/freeswitch/storage cache_dir=/var/cache/freeswitch data_dir=/nix/store/xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx-freeswitch-1.xx.x/share/freeswitch localstate_dir=/nix/store/xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx-freeswitch-1.xx.x/var/lib/freeswitch
And now I’m trying to remember how I actually set the script_dir
to be something else.
Ah, it’s by providing a “-scripts
” argument when launching FreeSWITCH.
So I need to modify my systemd service that adds that.
Enabling TTS in NixOS
Looks like I need to override the modules
part of pkgs.freeswitch
to get stuff like mod_flite
or mod_tts_commandline
working.
Looks like there was a bug with modules in Nixpkgs being incorrectly named “ast_tts
” instead of “asr_tts
”.
Speech recognition
I was trying to figure out “detect_speech
” but it looks like “unimrcp
” was removed from FreeSWITCH and mod_pocketsphinx
probably won’t work since pocketsphinx
has been removed from nixpkgs.
Vosk integration with FreeSWITCH seems interesting.
WebRTC
One idea for connecting to FreeSWITCH via WebRTC is to use the Janus WebRTC gateway. See an example at https://janus.conf.meetecho.com/siptest.html.
