With automatic-in processing, the CO processes all the digits of an incoming call. The CO then seizes a trunk from the trunk group. As processing is complete, the call connects directly to a destination identified in the communication server software. The destination can be a phone, a queue in which callers wait to be answered in the order in which their call was received, or a special treatment like an announcement.

You can assign each automatic-in trunk group to an ACD split. Communication Manager directs all incoming calls from an automatic-in trunk group to the assigned split. ACD then distributes the calls to the agent extensions assigned to the split based on the assigned call distribution method.
