IP Phone Administrator Guide

The IP phones allow you to lock or unlock programmable keys, softkeys, hard 
keys, cordless handset keys, and expansion keys (for expansion modules). When 
key locking is enabled, the phone uses the server settings and ignores any 
previous local configuration. A user cannot override the configuration of a locked 
key.

You can lock and unlock keys using the configuration files, the IP Phone UI, or 
the Aastra Web UI. When viewing the locked key via the Aastra Web UI, the key 
is grayed out (disabled) and cannot be changed. Locking is dynamic for XML 
pushes.

You use the following “locking” parameters in the configuration files to lock the 
softkeys and programmable keys on the 53i, 55i, 57i, and 57i CT. The locking 
parameters impact existing softkey and programmable key parameters as shown 
in the table below.
