Create and configure a UM IP Gateways in Exchange Server 2010

[Spy$Eyes]

An IP gateway for Unified Messaging (UM) creates a logical link between the IP gateway device, the UM IP gateway and a single or multiple UM hunt groups. When you create a new UM IP gateway, unified messaging servers enable the production of compounds with a new IP gateway or IP PBX phone system (Private Branch eXchange), the / for the SIP (Session Initiation Protocol) enabled. Instantly after you generate a UM IP gateway, you should create a UM hunt group and dispense the UM hunt group then the UM IP gateway. The UM IP gateway can be allocated to multiple UM dial settings by one or more UM hunt groups are created.

Create a UM IP gateway with the Exchange Management Console

Before you can execute this modus operandi, you have the appropriate permissions are assigned.

1. Navigate in the console tree to Organization Configuration> Unified Messaging.
2. Click in the workspace tab UM IP gateways.
3. Click the action pane, click New UM IP Gateway.
4. Fill in the wizard for new UM-IP gateway, the following fields:

• Name Use this text box, type a unique name for the UM IP gateway in one. This is the display name that appears in the Exchange Management Console. If the name of the UM IP gateways must change to create, you must first present the UM IP gateway is deleted and then another UM IP gateway be created with the name. The UM IP gateway name is required, but is used only for display. As used in your organization may be several UM IP gateways, you should use descriptive names for your UM IP gateways. The maximum length of a UM IP gateway name is 64 characters, spaces must be included.
• IP Address, a UM IP Gateway IP address or a fully qualified domain name (FQDN) be configured with one. Use this box to indicate that the IP gateway or SIP-enabled IP-PBX configured IP address. In this text box, alphabetic and numeric characters are permitted, but must properly formatted IPv4 addresses can be entered. IPv6 addresses can be entered, although in this field are not supported.
• Fully qualified domain name (FQDN) A UM IP Gateway IP address or a fully qualified domain name (FQDN) be configured with one. Enter in this text box, type a FQDN for the UM IP gateway or a SIP-enabled IP / PBX. This text box accepts only valid FQDN that are formatted correctly.
• To enable MTLS (Mutual Transport Layer Security) to between a UM IP gateway and dialing rules that are in the SIP secured or protected mode run, you must configure the UM IP gateway with an FQDN. You must also configure the Gateway for the monitoring of port 5061 and ensure that IP gateways or IP PBXs also for the monitoring of port 5061 on Mutual TLS requirements have been configured. To configure a UM IP gateways, the following command:
  
  Set-UMIPGateway-identity MyUMIPGateway port 5061st
  If you make use of an FQDN, you must also make certain that you have appropriately configured for the IP Gateway a DNS host record to the host name is suitably resolved to an IP address. If you use an FQDN as an alternative of an IP address and have changed the DNS configuration for the UM IP gateway, you must disable the UM IP gateway and re-activated to make sure that the configuration information for the UM IP Gateway will be updated correctly in Active Directory.
• Dialing rules, click the Browse button to to select the UM dial settings that you want to assign IP gateway to the UM. If you select the UM dial settings for the assignment to a UM IP gateway that is also a UM hunt group created and associated with this UM dial settings. If you select the UM dial settings, you must create a UM hunt group manually and this will create the UM IP gateway assigned.

5. Confirm completion of the page if the UM IP gateway has been successfully created:

• The status of Completed indicates that the wizard has completed the task successfully.
• The status of error indicates that the task was not completed. If error occurs when you run the task one, look in the summary for an explanation, and then click Back to make configuration changes.

6. Click Finish to complete wizard for new UM IP gateway to complete.

Configure the properties of UM-IP gateways with the Exchange Management Console

After following the above mentioned steps, you should proceed with the following :

• Outgoing calls through this UM IP gateway to allocate you select this check box to enable the UM IP gateway recognizes outgoing calls and processed. This setting does not work on call transfers or through an IP gateway incoming calls. When you create the UM IP gateways this setting is enabled by default. If you disable this setting, callers can to the dial settings are assigned to outgoing calls over the field in the address specified IP Gateway not working.
• (Message Waiting Indicator) allow MWI Check this box if the UM IP Gateway voice mail notifications to the user will be sent on calls to. With this setting, the UM IP gateway to send and receive SIP NOTIFY messages for users and. The setting is enabled by default and allows you to send MWI notification messages to users. Most of the legacy voice mail systems include a function MWI (Message Waiting Indicator). In the most common form of the voice mail subscribers to the entrance of a new voice message on a signal LED displays on the phone. MWI (Message Waiting Indicator) can refer to any mechanism that signals the presence of a new message. The voice mail message can not be it new or queried. The reference to the entrance of a new speech is with clients such as Outlook and Outlook Web App in your Inbox. He may take the form of an SMS (Short Messaging Service) or by text message to a registered mobile phone as an outgoing call from an Exchange UM server in a preconfigured phone with playback of the new element or as a signal lamp on the phone of a user.

In this example, Gateway is the IP address of the UM IP MyUMIPGateway changed.

Set-UMIPGateway identity MyUMIPGateway-Address 10.10.10.1

This example prevents the UM IP Gateway receives incoming calls and outgoing calls are stopped.

Set-UMIPGateway identity MyUMIPGateway-Address 10.10.10.1 status 2 OutcallsAllowed $ false

In this example, it is possible for the UM IP gateway to act as an IP Gateway Simulator. The sample cmdlet can be used to test UMConnectivity with.

Set-UMIPGateway identity MyUMIPGateway simulator $ true
