Preliminary Pickup Query And Monitoring; Switching Preliminary Pick-Up Query And Monitoring For Subscribers On/Off - Auerswald COMpact 4000 Operation Manual

Preliminary Pickup Query and Monitoring

The PBX supports the SIP function BLF (in accordance with RFC 4235). BLF allows VoIP end
devices to monitor other subscribers and receive information about their calls.
Support of the SIP function BLF provides the following functions:
• Preliminary pick-up query: A preliminary pick-up query allows a subscriber, even before
a pick-up, to see which caller he would be picking up. Based upon the phone number of the
caller, the subscriber can then decide whether to pick up the call or not. As precondition,
the called subscriber 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 subscribers, 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 subscriber 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 subscribers and groups who own the boxes or have redirected their calls to them.
You can use this functions with the following VoIP end devices:
Auerswald VoIP system telephones and standard VoIP telephones
Other subscribers are monitored with the help of the LEDs of those function keys which are
assigned to speed dialling (optional, see manual for the telephone).
Standard VoIP end devices of other vendors
As precondition to support the SIP function BLF, the SIP convenience package must have been
unlocked (optional, see chapter Important Information > Product Details > Basic Assembly and
Extensions).
Monitoring of other subscribers on the same PBX depends on the end device (see manual for
the end device).

calls of the subscriber is available for evaluation by BLF.
