Definition of Call Screening
Call screening enables the receiver to manage incoming calls in the manner desired. Many options are available as call screening features, such as caller ID. Most major phone carriers provide call screening services.
-
Caller ID
-
If a phone has a display unit, the caller can be identified by opting in for the caller ID feature. This enables the receiver to see who is calling prior to answering the phone. Even unlisted telephone numbers will be shown on the display; the only numbers not show are ones where the caller has opted to permanently block their number.
Caller ID Block
-
Just as incoming numbers can be shown via caller ID, so can the receiver's. The receiver's number can be blocked through a call screening feature known as caller ID block. This feature can be applied per call by dialing a special code, or per telephone line, which will block the number from being shown at all times.
-
Routing Specific Numbers
-
Some companies offer a call screening feature that enables rerouting of specific numbers. The calls will automatically be routed to a message indicating that the call is not being answered or to other phone numbers. For instance, calls from a 415 area code can automatically be routed to a San Francisco office and calls from a 203 area code can be routed to a Connecticut location.
Listening to Voice Mail
-
With the call screening feature added, the recipient of a call can route a call directly to voice mail and listen simultaneously as the message is being left. The recipient has the option to answer the call mid-message while using this feature.
Types of Phones
-
Call screening can be used on landlines and cellular phones and is provided by companies that offer phone services such as voice mail or toll-free numbers. Call screening features also are provided by services such as Google Voice, RingCentral and eVoice.
