Front End Server Properties: IM Conferencing

Use this tab to configure the listening address and port for group instant messaging (IM).


The IP address and port on which the Front End Server receives messages related to group IM conferencing.

IP address

The IP address that is associated with the IM Conferencing component of the Front End Server. The default is All, which we recommend 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. To refer to the server by using a single, specific IP address, click IP address, and then click the IP address that you want to use.

SIP listening port

The port on which the IM Conferencing component of the Front End Server receives SIP signalling messages.

The IM conferencing component of the Front End Server manages group IM conferences for users of Microsoft Office Communicator 2007 and later. During installation, the Front End Server is configured with default settings for IM conferencing. 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.

For details, see the Operations section of the Office Communications Server Technical Library.
