ONFIGURATION
If you allow telephone users to configure button mappings on their
■
own devices, a telephone user can override any button mappings that
you set unless you lock the button to prevent changes. To lock a
button, click Telephone Configuration > Telephone Groups, and then
select a telephone group and click the Button Mappings tab. The
Button Mapping window includes Lock check boxes next to each
programmable Access button. Enable the Lock check box to prevent
telephone users from mapping a function to the selected button.
CoS permissions do not apply to hunt groups. This means a CoS
■
cannot prevent you from configuring operators in a Hunt Group.
Service classes control these types of calls:
Intercom
■
External (local, long distance, international, long distance toll-free,
■
and long distance toll)
CO Code (optional telephone company services, such as Call Waiting)
■
Trunk to trunk transfers
■
Off-site Notification
■
Configurable operators (destinations pre-selected by the user to which
■
callers are sent if those callers reach the telephone user's voice mail)
