# MiVoice Business ICP Programming for MiTAI MWI

Notes:

- The MiTAI Messaging MWI does not support the configuration of MiVoice Business ICP as a gateway.

- In an environment with resilient MiVoice Business ICPs, an open communication path is required between the ICPs whenever a MWI messaging event occurs. Without a communication path, events will not be synchronized and the user's message waiting lamp will fail to turn on/off correctly.

MiTAI MWI must be configured on both the MiVoice Business ICP and the NuPoint Unified Messaging systems.

### Creating an HCI Reroute Hunt Group on the MiVoice Business ICP

For programming the MiVoice Business ICP to support HCI Reroute Hunt Group, the following steps need to be performed on the MiVoice Business ICP side:

1. Open the MiVoice Business ICP System Administration Tool and in the Selection: drop-down menu, click System Administration.

2. Navigate to the Hunt Groups form (click Users and Devices > Group Programming > Hunt Groups).

3. Click Add.

4. In the Hunt Group field, type the hunt group number.

5. In the Hunt Group Type field, select HCIReroute.

6. Click Save.

7. Navigate to the Call Rerouting Always Alternatives form (Call Routing > Call Handling > Call Rerouting Always Alternatives). Choose an unused Always Alternative Number, then click Change. Do not use Call Reroute number 1.

Note: Remember the Always Alternative Number, because you need it in the final step of this procedure.

8. In the Call Rerouting Always Alternatives form, change all four Always Originating Device values to Reroute, and change Directory Number to Reroute to to the NP-UM messaging hunt group pilot number.

9. Click Save.

10. Navigate to the Call Rerouting form (Call Routing > Call Handling > Call Rerouting).

11. In the Call Routing folder, navigate to the pilot number of the HCI Reroute hunt group.

12. Click Change.

13. In the Call Rerouting window, change the Call Rerouting Day, Call Rerouting Night1, and Call Rerouting Night2 numbers to the Call Rerouting Always Alternative number created in Step 7.

Note: Message waiting indicators are affected by timer settings in the MiVoice Business system. To avoid premature extinguishing of MWI, ensure that the SUPERSET Callback Message Cancel Timer parameter in the System Options form is BLANK. (An entry in this field sets a time limit for MWI to be displayed, after which the indicator is extinguished.)

For detailed programming information, refer to the MiVoice Business System Administration Tool Online Help.
