<div dir="ltr">Hi,<br><br>Whenever Asterisk restarts or reboots, what should happen to ongoing subscriptions (MWI, Dialogs, ...) ?<br>Should
hardphones discover by themselves Asterisk has restarted so phones
should renew Subscriptions or shall Asterisk send a Notify or another
SIP message telling phones something special occurred ?<br>
<br>Looking at SIP SUBSCRIBE/NOTIFY messages contents, I can see tags
that, IMHO, should be meaningless without a proper SUBSCRIBE/200OK
exchange.<br><br>Of course, each SUSCRIBE will expire, so normally, phones should renew subscriptions by themselves but it could take a rather long time (here, subscriptions last 1 hour).<br><br>Regards</div>
