- the ANI/DNI-based Solution
- the Call Rerouting-based Solution

## ANI/DNI-based Solution

From the Console point of view, it is the Automatic Number Identification (ANI) and Dialed Number Identification (DNI) information that is important. Automatic Number Identification (ANI) and Dialed Number Identification Service (DNIS) identify numbers that are transmitted on an incoming trunk from the Central Office (CO).

ANI provides the caller's telephone number (and name if supported); DNIS provides the number dialed by the caller. The ANI/DNIS/ISDN Number Delivery feature allows the system to identify and use these digits when they are received.

When ANI/DNI is enabled on the MiVoice Business, the MiVoice Business Console places the ANI number in the Console Name field. The DNI number is placed in the Console's Number field. The ANI/DNI names, if available from the external trunk line, are removed in order to deliver the two numbers (ANI/DNI) to the MiVoice Business Console.

The Multiple Company Directory feature takes advantage of the DNI number information and presents the MiVoice Business console operator with Company Greeting information.

The Multiple Company Directory feature relies on the MiVoice Business being configured to display both the ANI and DNI numbers on the MiVoice Business Console display.

The information that appears on the display is obtained from the Company Information CSV file. See Configure Directory Data and Mapping Files for more information.

For detailed information on ANI/DNIS programming on the MiVoice Business and the MiVoice Business Console, see the Multiple Company Directory help topic in the MiVoice Business System Administration Tool help.

## Call Rerouting-based Solution

Multiple Company Directory can be programmed using a method that doesn't require DNI service to the MiVoice Business. This method uses the MiVoice Business Call Rerouting-based Solution.

Overview

- The Multiple Company Directory Greeting information is only displayed when the call is actually answered.

- In other words, there is no Greeting or other additional company information in the Incoming Calls queue.

- The Caller's Number and Name (if provided by the Trunk line) are displayed in the Source window upon Answer.

- This differs from the ANI/DNI solution where the ANI number is displayed in the Name field and the DNI number is displayed in the Number field. In other words, the benefit of this approach is that the Caller’s name is presented.

- DNI service to the MiVoice Business is not required.

- Depending on the MiVoice Business programming, the displayed Company Number in the Configurable Source Panel may not match the actual number dialed by the Caller.

- The MiVoice Business programming required to achieve the Multiple Company Directory using Call Forward - Busy requires an IP set license on an IP set that provides the Call Forward - Busy condition.

- The IP set itself will not be usable as this set is configured to always be busy (always in DND).

Introduction to Programming the MiVoice Business

- The answer point for incoming trunk calls requires the ability to forward calls to the MiVoice Business Console when deemed busy or in DND.

- The MiVoice Business Console upon answering this forwarded call must display the call as a Call Forwarded - Busy call.

- When in Multiple Company Directory mode, the MiVoice Business Console will detect this answer situation and utilize the forwarded number as the basis for the Company Number.
