hi,
I’ve just figured out, that I have to add a Sound language via Web GUI Admin → Sound Languages and set the Global Language to my new created language (german in my case).
found at
now if I call the extension where the announcement is set, the sound from the correct location /var/lib/asterisk/sound/de/custom/ is played. but if I want to edit this system recording, I get an xxx-TMP.wav file, and the old system recording is not overwritten.
a known bug? didn’t found anything about this
