Call Manager Express allows us to configure a line button to just be a "Monitor" line where we can see call state info for that extension tied to the monitor line, but we can't pick that line up. (This is in a secretary sitution without using IPMA).
Can we do this with UCM 6 yet? Only configure a line button to be a monitor and prevent someone from picking up that line?
In CCM 6.x this is a traditional BLF (Busy Lamp Field) which is used to monitor On/Off Hook, Busy/Idle conditions on users phones, as well as having a Speeddial functionality for fast dialing and Transfers.These keys can't be used to answer actual calls.
In Cisco Unified CallManager 6.x this is called - Speed Dial Presence
Cisco Unified CallManager supports the ability for a speed dial to have presence capabilities via a busy lamp field (BLF) speed dial. BLF speed dials work as both a speed dial and a presence indicator.Only the system administrator can configure a BLF speed dial; a system user is not allowed to configure a BLF speed dial.
So you have basically a speed-dial button that also lights up when the person is on the phone.
Hope this helps!
