Configuring Connections for Servers

Topic Last Modified: 2009-03-06

Configuring a Standard Edition server or Front End Server in an Enterprise pool requires specifying the addresses, ports, and transports that this server uses for inbound connections.

To add or edit an incoming connection for a Standard Edition server or Front End Server in an Enterprise pool

  1. Open the Office Communications Server 2007 R2 snap-in.

  2. In the console tree, expand the forest node, and then do one of the following:

    • For an Enterprise pool, expand Enterprise pools, expand the pool, expand Front Ends, right-click the Front End Server that you want to configure, and then click Properties.
    • For a Standard Edition server, expand Standard Edition servers, expand the pool, right-click the server, click Properties, and then click Front End Properties.
  3. On the General tab, in Connections, do one of the following:

    • To remove a connection, click the connection, and then click Remove.
    • To temporarily disable a connection, clear the check box next to the connection.
    • To add an address to the list of connections, click Add.
    • To change the configuration of an address in the list of connections, click the connection, and then click Edit.
  4. If you are adding or editing a connection, in the Add Connection or Edit Connection dialog box, in Listening Address Settings, specify the appropriate connection information:

    • IP address. In the list, click the IP address associated with the Front End Server or, if you do not want to use a specific IP address for this connection, click All. The default is All, which is recommended if IP addresses in your environment are assigned dynamically or if your environment uses the fully qualified domain name (FQDN) to refer to the server instead of the IP address.
    • Port. Type the number of the port you want to use to listen to the incoming connection. This is the port on which the Front End Server receives SIP messages. By default, the conventional SIP ports are used.
    • Transport. In the list, click the transport protocol to be used for incoming messages, including sending messages to the Front End Server over this connection. Specifying TLS or MTLS rather than TCP allows encrypted communications with this server, helping make connections to this server more secure.

    You can configure multiple listening addresses, but in order to avoid conflicts, you can configure only one for each transport type. When you configure a new listening address, ensure that you choose a port that is not already in use on the computer.

  5. In Connections, ensure that the check box of each connection that you want to use is selected, and then click OK.
