We are using the mailboxes in the AOR table so our Cisco phones can subscribe to Message Waiting Indications.
Once in a while the light would not be on even with new messages, so I did a trace with wireshark and found something weird.

The phone boots and subscribe sucessfully to MWI with a voicemail subscribe interval of 86400.
If I look at my wireshark trace I can see that asterisk sends a sollicited notify 5 times. Is this normal?
I have also noticed that the Subscription state is going from 83544 seconds to 432 seconds and it expires in the last notify.
