MiTAI MWI support requires configuration in the server and in Mailbox maintenance.
The NuPoint Unified Messaging server needs to know the HCI Reroute Hunt Group number to generate the proper MWI messages. Set this up in the MiVoice Business ICP Integration menu:
From the Main menu, select (S) System Maintenance, (R) Reconfiguration, (R) Reconfigure System, (G) Offline Menu, (I) Server Options and Configuration, and then (C) Configure Mitel MCD integration.
Select (H) HCI Reroute Hunt Group Number for Mitai MWI and enter the HCI Reroute Hunt Group number.
