MP56 SIP questions

Is it possible to trigger auto provisioning via SIP NOTIFY?

Is it possible to disable user access to Firmware Upgrade?

When we receive a voicemail, there is a popup with 3 buttons. Exit and View make the popup go away. Connect makes the popup go away but it comes back almost immediately. None of the buttons allow me to listen to the voicemail. We send a SIP NOTIFY with the following content:

Messages-Waiting: yes
Message-Account: sip:*98[atsymbol]pbx.local;transport=TLS
Voice-Message: 2/0 (0/0)

Is there a way to disable the voicemail popup and also the missed call popup?

Is there any way to configure a voicemail button other than via the directory?

Asterisk pjsip_notify.conf to trigger auto provisioning via SIP NOTIFY:

Event=>check-sync\;reboot=true
