To lock the phone, use a Feature Access Code (FAC) on an analog telephone.

On a digital telephone, use an FAC or a feature button.

Station Lock facilitates:

The feature button will light when the user will press the button to activate Station Lock. When a user attempts to place a call, the system generates a special dial tone to indicate that the Station Lock feature is active.

H.323 or DCP phones support the Station Lock functionality of Communication Manager. SIP phones do not support the functionality.

If a digital or an IP telephone has a Station Lock button, but uses an FAC to activate the feature, the system generates the special tone. If a digital or an IP telephone has a Station Lock button and uses this button to activate the feature, the system generates the special tone too. If a digital or an IP telephone does not have a Station Lock button and uses an FAC to activate the feature, the system generates the special tone.

On a digital telephone, use a Station Lock button instead of an FAC to activate Station Lock.

Any user who knows the systemwide FAC for Station Lock and the Station Security Code (SSC) of a specific telephone can lock or unlock the telephone.

A user can also lock or unlock a telephone from a remote location.

The attendant console can lock or unlock other telephones. The attendant console cannot be locked.
