Configuring IM Conferencing for Servers

Topic Last Modified: 2009-03-06

The IM Conferencing component of the Front End Server manages group IM conferences. During installation, the Front End Server is configured with default settings for IM conferencing. On the IM Conferencing tab, you can configure the IP address and the SIP listening port to be used for group instant messaging (IM):

  • IP address: This is the IP address that is associated with the IM Conferencing component of the Front End Server.
  • SIP listening port: This is the port on which the IM Conferencing component of the Front End Server receives SIP signaling messages. You can configure multiple listening addresses, but in order to avoid conflicts, you can configure only one for each transport type. Use a port that is not already in use on the computer.

If you change the settings, ensure that the settings you choose do not conflict with settings for other Office Communications Server components that are running on the same computer.

To configure IM conferencing for a Front End Server

  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, click Properties, 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. Click the IM Conferencing tab.

  4. In the IP address box, click the IP address that you want to use. The default is All, which is recommended if IP addresses in your environment are assigned dynamically or if your environment will use the fully qualified domain name (FQDN) to refer to the server instead of the IP address.

  5. In the SIP listening port box, type the port number that you want to use. Ensure that you specify a port that is not already in use on the computer.
