Ok, if I go to the phone configuration and explicitly enable mwi 
subscription it works now (while using mailboxes in the aor). Obviously 
this is a bit of a pain because it means that I have to change all the 
phones configurations (ok, not a pain because of provisioning but I am 
lazy ;) .  All my pre Asterisk 13 installations just work without any 
specific mwi parameter on the phones and I was trying to reproduce that 
same behaviour.  Up until Asterisk 11 all my phones blink when there is 
a VM waiting and since we moved to 13 and PJSIP that is the only thing 
we were missing.

Thank you for the solution.
