After assigning an extension, the phone must be rebooted in order to pick up the configuration file from the
UCM6510. During this process, the phone will boot up, request for config file, download the config file, then
reboot once more in order to apply the changes.
After the phone is completely booted, navigate to PBX->Basic/Call Routes->Extensions page to see the
extension status. The SIP status will show a green circle for a successful registration.
