Updated: January 21, 2005

Applies To: Windows Server 2003, Windows Server 2003 R2, Windows Server 2003 with SP1, Windows Server 2003 with SP2, Windows Server 2008, Windows Server 2008 R2, Windows Server 8 Beta

To specify an H.323 gateway or proxy

  1. Open Phone and Modem Options in Control Panel.

  2. On the Advanced tab, in Providers, click Microsoft H.323 Telephony Service Provider, and then click Configure.

  3. In Configure H.323 Service Provider, select one of the following:

    • To specify an H.323 gateway, select the Use H.323 gateway check box, and then type the computer name or IP address for the gateway.

    • To specify an H.323 proxy, select the Use H.323 proxy, and then type the server name or IP address for the proxy.


  • To perform this procedure, you must be a member of the Administrators group on the local computer, or you must have been delegated the appropriate authority. If the computer is joined to a domain, members of the Domain Admins group might be able to perform this procedure. As a security best practice, consider using Run as to perform this procedure.

  • To open a Control Panel item, click Start, click Control Panel, and then double-click the appropriate icon.

  • An H.323 gateway connects the IP network with a switched service network, such as the public switched telephone network (PSTN). Your telephony administrator can provide the correct name or IP address to enter here.

  • A proxy server acts as a firewall or security barrier between your intranet and the Internet, preventing other people on the Internet from gaining access to confidential information on your internal network or computer. Your telephony administrator can provide the correct name or IP address to enter here.

Information about functional differences

  • Your server might function differently based on the version and edition of the operating system that is installed, your account permissions, and your menu settings. For more information, see Viewing Help on the Web.
