[Freeswitch-users] MWI sent without subscriptions (SIP)

This is to send a NOTIFY right after REGISTER, I'm talking about when a
new message is received (SWITCH_EVENT_MESSAGE_WAITING).

Digging deeper, on function "actual_sofia_presence_mwi_event_handler" of
sofia_presence.c, we can see that a NOTIFY is sent to subscribed devices
(around lines 568-590), but also to registered devices (around lines
592-607).

François.
