NetMeeting COM T.120 Application API

  • Article

The Windows® NetMeeting® 3 low-level T.120 API uses T.120-compliant standards for T.120 application software. The software supplies or uses conference-independent services and transport control. This API lets NetMeeting client applications do the following:

  • Join and leave a conference at will.
  • Access remote system resources such as the registry, channels, and tokens after joining a conference.
  • Query applet rosters.
  • Launch an applet remotely.
  • Replace the underlying transport.

In addition, this transport API provides the following features.

  • Compatibility with earlier versions of NetMeeting that used Public Switched Telephone Network (PSTN) framing.
  • The ability to disable the Windows Socket connection while using the plug-in transport.

The IApplet and IAppletNotify API replaces earlier versions of NetMeeting support for the conference-independent portion of Generic Conference Control (GCC) Applet Service Access Point (SAP). The IAppletSession and IAppletSessionNotify API replaces a combination of GCC Applet SAP and Multipoint Communication Service (MCS) Applet SAP.

This section defines the NetMeeting 3 low-level T.120 COM API. The interfaces and functions can be used with NetMeeting client applications developed in C/C++ or other programming languages that support COM to develop T.120 Application applications.

Descriptions of how NetMeeting uses the T.120 conferencing standards can be found in the Windows NetMeeting 3 Resource Kit, available from Microsoft Windows NetMeeting Web site.
