•Preliminary pick-up query: A preliminary pick-up query allows a user, even before a pick-up, to see which caller he would be picking up. Based upon the phone number of the caller, the user can then decide whether to pick up the call or not. As precondition, the called user or group must have enabled Preliminary pick-up query and monitoring.

•Monitoring or BLF (Busy Lamp Field): BLF allows VoIP end devices to monitor other internal users, groups, waiting positions of call parking, voice mail/fax boxes or door terminals and receive information about their calls. As precondition for the display of phone numbers, the monitored user or group must have enabled Preliminary pick-up query and monitoring. Whether voice mail and fax boxes can be monitored in this way depends on the users and groups who own the boxes or have redirected their calls to them.

•Auerswald/FONtevo VoIP phones (except COMfortel VoIP 2500 AB): Other private branch exchanges are monitored with the help of the LEDs of those function keys which are assigned to speed dialling.
