Auto-In mode
An agent can receive a call immediately. The zip tone is shorter than a second, and the call is presented to the agent immediately afterwards. The agent usually has TACW administered on the phone to have a brief interval for handling the previous call.
After the TACW timer interval, the agent can be assigned to another call. With an automatic answer enabled, the phones displays the next call in less than a second after the agent is assigned to that call.
