Information About Phone Reset
If a device is not registered with Cisco Unified Communications Manager, you cannot reset or restart it.
If a device is registered, to restart a device without shutting it down, click the Restart button. To shut
down a device and bring it back up, click the Reset button. To return to the previous window without
resetting or restarting the device, click Close.
Note Resetting a gateway/trunk/media devices drops any calls in progress that are using that
gateway/trunk/media devices. Restarting a gateway/media devices tries to preserve the calls in progress
that are using that gateway/media devices, if possible. Other devices wait until calls are complete before
restarting or resetting. Resetting/restarting a H323 device does not physically reset/restart the hardware;
it only reinitializes the configuration loaded by Cisco Unified Communications Manager.

Reset a Cisco Unified IP Phone at any time by following these steps:

latest configuration changes by using the least-intrusive method.
