A service that allows you to connect an H.323-based communication system on the Internet to a telephony system. You can use H.323 gateways to connect corporate networks to telephony systems for supporting integrated audio and video conferencing.
For example, you can use an H.323 gateway to place a Microsoft NetMeeting call to someone’s telephone. The Uniform Resource Locator (URL) format for doing so is “callto:<address>”, in which <address> is the fully qualified domain name (FQDN), IP address, or e-mail address of the person you are calling.
You can use this URL as a link on a Web page or enter it directly in the address box of your Web browser.

NetMeeting does not include any H.323 gateway software, but it will support third-party gateways when they become available.
