Line Monitoring/BLF/Call Pickup
Working closely with other members of your team sometimes involves answering their phones. Line Monitoring, or
Busy Lamp Field (BLF), allows to you set one of your unused phone lines to monitor the status of another user.
This functions as a speed dial and
can be used to answer a call ringing on another person’s phone, or to see if
your team member is currently on the phone or not.
Note: These buttons must be configured in the voice web portal by your administrator. The BLF/Presence button
does not provide ringing or Caller ID.
Shared Lines
When a team wants to work together to answer the same calls, this simple method allows multiple phones to
share the same extension. All calls ringing to the assigned extension will ring any of the phones sharing this line.
When receiving a call, the IP Phone display will show which extension is ringing.
Note: Users can also place an outbound call from their normal extension or choose from any shared extensions
they have configured.
Note: These buttons must be configured in the voice web portal by an administrator.
