auto-in trunk group
Trunk group for which the CO processes all of the digits for an incoming call. When a CO seizes a
trunk from an auto-in trunk group, the switch automatically connects the trunk to the destination —
typically an ACD split where, if no agents are available, the call goes into a queue in which callers are
answered in the order in which they arrive.
Auto-In Work mode
One of four agent work modes: the mode in which an agent is ready to process another call as soon as
the current call is completed.
Automatic Alternate Routing (AAR)
A feature that routes calls to other than the first-choice route when facilities are unavailable.
Automatic Callback (ACB)
A feature that enables internal callers, upon reaching a busy extension, to have the system
automatically connect and ring both parties when the called party becomes available.
Automatic Call Distribution (ACD)
A feature that answers calls, and then, depending on administered instructions, delivers messages
appropriate for the caller and routes the call to an agent when one becomes available.
Automatic Call Distribution (ACD) split
A method of routing calls of a similar type among agents in a call center. Also, a group of extensions
that are staffed by agents trained to handle a certain type of incoming call.
Automatic calling unit (ACU)
A device that places a telephone call.
