Unified Messaging IP gateway
The IP gateway must be identified in the UM IP gateway object configuration for the UM server to be able to communicate with it.
Integrating voice with a data network does increase its exposure to data network vulnerabilities. For additional security, the Unified Messaging server is configured with a list of trusted SIP peers. If a SIP connection attempt is made from an untrusted SIP peer, the connection attempt will be blocked and an 1187 event will be logged.
After configuring the UM IP gateway object, you can associate it with the UM Dial Plan you created first. Be sure to verify that there is a UM server configured for the UM dial plan.
The UM IP gateway will also need at least one UM hunt group associated with it so that it knows the range of user extensions it covers. Fortunately, when you associate a UM dial plan with the UM IP gateway, a default UM hunt group will also be created if one does not already exist.
Creating a new UM IP Gateway
Use the following steps to create a new UM IP gateway:
- Open the EMC with an administrator account that has the Exchange Organization Administrator role.
- Expand "Organization Configuration" and click "Unified Messaging."
- Click the "UM IP Gateways" tab.
- Select "New UM IP Gateway" in the "Actions" pane.
- Type the name of the UM IP gateway in the "Name" field, as shown below.
- Type the IP address for the UM IP gateway in the "IP Address" field or type the FQDN in the Fully qualified domain name (FQDN) field.
- Click "New."
- Click "Finish."
As an alternative to the EMC, you can also use the New-UMIPGateway cmdlet in the EMS, like in this example:
[PS]C:>New-UMIPGateway -Name "AudioCodes-Mediant 2000" -Address 192.168.10.254
