Account owners and admins can view the ZTP process status for common area phones, unassigned/assigned desk phones, and ATAs when viewing the device list. They can also retry the connection to the ZTP server in the case where the first attempt failed. This is useful if a device loses connection to the ZTP server, meaning the device is not getting automatic firmware upgrades or is the provisioning process failed.

Note: You can also re-sync desk phones to pass settings from the Zoom web portal to desk phones.
