# MiVoice Office 250 Integration Configuration Overview

The Mitel MiVoice Office 250 and NuPoint Unified Messaging integration requires configuration of three different applications:

- MiCollab

- NuPoint Unified Messaging (NuPoint UM)

- MiVoice Office 250

Several prerequisites must first be satisfied before NuPoint UM can be integrated with the MiVoice Office 250 via a SIP Gateway connected to IP endpoints.

To integrate NuPoint UM with the MiVoice Office 250, the system administrator must configure a cluster node that represents the peer MiVoice Office 250 and the line group(s) that represent the SIP trunk(s). Line(s) must be added to the line group and mapped to the SIP ports.

The system administrator must configure a SIP Gateway (add a SIP Gateway as a Cluster Node) and then configure SIP trunks as line groups before calls can be made from IP Endpoints to NuPoint UM. The information entered in these steps provides NuPoint UM with SIP Gateway IP/port data and Line mapping details used to accept calls from the SIP Gateway and re-direct them to available NuPoint UM lines. When Lines are linked to a SIP Gateway Cluster Node, incoming SIP calls can be accepted and routed to available NuPoint UM Lines for SIP.

Refer to Add a Line Group for instructions to configure a SIP Gateway and to configure NuPoint Unified Messaging lines for a SIP Gateway.

Once the configuration is complete, IP endpoints will call a Pilot Number that routes to an available NuPoint UM line and will hear a greeting prompt, such as "Welcome to the message center. Please enter a mailbox number or wait."

## Constraints

- Although the NuPoint UM software system does not prevent the system administrator or installer from configuring and setting up a SIP integration that includes Digital Media Gateway (formerly PIMG, HD-PIMG, or TIMG) and the MiVoice Office 250, this integration mix is not supported.

- NuPoint UM will communicate with only one MiVoice Office 250.

- Although you can configure more than one MiVoice Office 250 node to communicate with NuPoint UM, it is not a supported configuration and many NuPoint UM features like MWI and Pager Notifications do not work with this type of configuration.

- The numbers used by the SIP interface to represent SIP ports (e.g. Port 5058 for NuPoint UM on MAS or 5060 for NuPoint UM Standalone) remain as unconfigurable data.

## External Dependencies

- The SIP component on the MiVoice Office 250 is required. Refer to the MiVoice Office 250 documentation for SIP configuration instructions.

- The MiVoice Office 250 must be configured to use the correct port for SIP communication from NuPoint UM. For NuPoint UM on MiCollab, use 5058; for NuPoint UM Standalone, use 5060.

- The configuration for MiVoice Office 250 on NuPoint UM requires a MiCollab license. Refer Applications > Users and Services > About UCC Licensing for more information on licensing.

Refer to the MiVoice Office 250 Integration Task Summary for configuration task lists for each of the applications.
