# Prerequisites for the MiVoice Office 250 Integration

The requirements stated below must be satisfied before NuPoint UM can be integrated with the MiVoice Office 250 via a SIP Gateway connected to IP endpoints.

1. The MiVoice Office 250 integration is supported only on MiCollab Release 1.2 or later. The configuration for the MiVoice Office 250 on NuPoint UM requires a MiCollab license. Refer Applications > Users and Services > About UCC Licensing for more information on licensing.

2. It is assumed that the SIP Gateway is running and correctly configured with IP Endpoints so that each endpoint has a registered extension.

3. Mitel Standard Linux (MSL) and NuPoint UM software must be installed and running on a computer system connected to the same physical network as the SIP Gateway. Also, full IP connectivity is assumed possible between NuPoint UM and the SIP Gateway, meaning that no security hardware or software is active.

4. MSL has been properly licensed using Mitel’s Applications Management Center server (AMC). NuPoint UM features to be used or tested must be enabled in the AMC Application Record. The Application Record ID is requested and the Application Record is "activated" during the MSL installation.

5. The NuPoint UM server is mapped from the SIP gateway by a Pilot Number and configured as a SIP Trunk.

6. The security settings on the NuPoint UM server must be modified so that it is possible to establish full telephony communication between the SIP Gateway and NuPoint Unified Messaging. Follow the procedure below to modify the security settings.

## Modifying the Security Settings for NuPoint Unified Messaging

You can grant server access privileges to additional networks:

1. Log into the MiCollab server console.

2. Under Configuration, click Configure Networks.

3. Click Add a new trusted network.

4. In the Network Address field, enter the IPv4 or IPv6 address of the network to designate as “local”.

5. In the Subnet mask or network prefix length field, enter the dot-decimal subnet mask or CIDR network prefix to apply to the Network Address. If this field is left blank, the system assigns a network prefix length of /24 for IPv4 networks or /64 for IPv6networks.

6. In the Router field, enter the IP address of the router you will use to access the newly-added network.

7. Click Add.

1. Note: Under some circumstances, modifying the "Local Networks" will not update security settings correctly. Should call connectivity or two-way audio not appear to be initiated correctly, the following command may be issued, as a last resort, to disable the NuPoint UM server firewall through a Linux console session: service masq stop.
