Rebooting Issues
How to reboot the IP phone remotely?
IP phones support remote reboot by a SIP NOTIFY message with “Event: check-sync” header.
Whether the IP phone reboots or not depends on the value of the parameter
“sip.notify_reboot_enable”. If the value is set to 1, or the value is set to 0 and the header of the
SIP NOTIFY message contains an additional string “reboot=true”, the IP phone will reboot
immediately.
