Replying to myself, for an unknown reason, MWI is weirdly working  :
- Phone icon inconsistently shows awaiting voicemails,
- NOTIFY message from Asterisk are still replied with "481 Call
Leg/Transaction Does Not Exist"

When base station is restarted, it will SUBSCRIBE its endpoints to Voicemail
Notifications :
- you can see SUBSCRIBE message
- you can see NOTIFY answer
- you can't see any "481 Call Leg/Transaction Does Not Exist" reply to this
NOTIFY message
