Only for one user, the voicemail BUSY.WAV will not play.
The file was recorded using the phone (*98 and so on)
I see the file in directory busy.wav
/var/spool/asterisk/voicemail/default/XXX
However, in CLI it doesn’t even check the file, it goes straight to playing:
<Local/XXX@from-internal-00000002;2> Playing ‘vm-intro.ulaw’ (language ‘fr’)
