Operational IP Phone Features Locking IP Phone Keys
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 only. 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 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.
