Pre-configuration of keys
With the Pre-configuration of keys feature, the Phone screen displays a pre-determined set of
phone keys for accessing features, applications, and line appearances. Using this feature, you can
add and access BLF lines and auto-dialing phone extensions.
Your system administrator does the phone key configuration. If pre-configured keys are forced,
you cannot customize the mapping and labels.
If pre-configured keys are not forced, you can change their mapping and labels as required.
The forced keys have a priority over customizable keys. This does not apply to Call Appearance,
Shared Call Appearance and Busy Lamp Field keys as they are not dropped but moved to a
different location.
Contact your system administrator if you need to replace, move, or relabel the forced keys.
Push-To-Talk
With the Push-To-Talk feature, you can call another user and have your call answered
automatically.
Note:
You can make only audio calls with this feature.
