SIP check-sync mechanism

The check-sync mechanism allows the initiation of a profile (configuration file) download from remote.


A SIP NOTIFY has to be used for sending the check-sync command. As additional information the protocol includes the switch, if a reboot has to take place (some operating systems need a reboot to make the new settings valid).

The following pictures show the principle of this.

The Nx70 does not need an reboot to activate provisioning parameter changes !!!

On customer request, we have added the option to reboot the device from remote via the check-sync with reboot=true command. 

  • Has to be enabled via auto-provisioning.
  • Due to security reasons, must be send to a valid SIP account of the handset or provisioning SIP account
    (Check-sync anonymous like some platforms use, will not trigger an reboot)
