A user or administrator can lock a phone to prevent it from being used or 
configured. Once the phone is locked, the user or administrator can enter their 
password to unlock the phone.

You can lock/unlock a phone using the configuration files, the IP Phone UI, or the 
Aastra Web UI.

You can use any of the following methods to lock/unlock a phone:

•

Using the IP Phone UI via the “Phone Lock” option in the Options Menu.

•

Using the Aastra Web UI via the path Operation->Phone Lock.

•

Using the configuration files to configure a key as “phonelock”, and then 
pressing the key to lock/unlock the phone.

•

Using the Aastra Web UI to configure a key as “Phone Lock”, and then 
pressing the key to lock/unlock the phone.

All of the methods above configure locking/unlocking of the
