A green steady LED for the button indicates that Call Screening is on but not currently screening
any calls. While a call is being screened, the button LEDs alternately flash red and green to
indicate that the connection has been established.
Considerations
Call Screening must be programmed on a button with lights.
I
This feature is not available at tip/ring, proprietary cordless, or wireless telephones.
I
This feature can be turned on only by pressing the programmed button. It cannot be accessed
I
by dialing the Call Screening feature access code.
An incoming call can be screened at that extension only if the extension is the Line Coverage
I
Extension for that line, the call has been transferred to that extension, or the call is an
intercom call to the extension.
If the user is currently on a line or intercom call, Call Screening is ignored.
I
After a call has been sent to the voice mail system, you cannot use the Call Screening feature
I
to screen that call. Call Screening must be on before or while the call is ringing at the
telephone.
Users cannot create a conference call while screening a call.
I
While a call is being screened, dialpad button pushes are ignored.
I
A user cannot enter program mode while screening a call.
I
Dialable features that interrupt Call Screening are: Last Number Redial (F05), Station Lock
I
(F21), Personal Speed Dial (F80-89), and System Speed Dial (F600-699).
Programmed buttons that interrupt Call Screening are: Do Not Disturb (F01), Save Number
I
Redial (F04), Last Number Redial (F05), and Station Lock (F21).
If the voice messaging system extension does not have Automatic Extension Privacy (#304)
I
turned on, other users can bridge onto the call. If a user bridges onto the call, a forward
disconnect signal is sent to the voice messaging system, and it disconnects from the call. This
causes the screening extension to be dropped from the call, and the person who bridged onto
the call is now talking to the calling party.
