Preliminary Pickup Query and Monitoring

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/FONtevo VoIP system phones and standard VoIP
phones (except COMfortel VoIP 2500 AB): 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 phone).
• 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 Activation).
