Telephony and Conferencing

Although NetMeeting supports multi-user data conferencing, you can connect with only one other person at a time with audio or video functions. Other audio and video troubleshooting issues are also described in the following sections.

Cannot place a call in NetMeeting

  • If you are in a network environment that uses a proxy server and are attempting to access a Web-based directory server or to contact someone on the Internet, verify that your proxy server supports NetMeeting. If the proxy supports NetMeeting, attempt to ping the directory using its DNS name or IP address to check availability.

  • If a gatekeeper is used to establish calls, you might have to log on to the gatekeeper using an established alias. Contact your system administrator for details.

  • Some directory names are case-sensitive; verify the correct capitalization used in a directory name before attempting to place a call.

  • If you cannot place a call using a computer name, try using their IP address. If the IP address is unknown, ping the computer you are attempting to call, using the full DNS name of the host.

Audio problems in NetMeeting

If the audio functions of NetMeeting application have worked previously, and any changes have occurred in the sound card device driver (such as upgrading to a full-duplex driver) run the Audio Tuning Wizard again in order to reconfigure the NetMeeting audio settings. If running the Audio Tuning Wizard does not solve the problem, check the hardware and driver configuration, as described in Troubleshooting H.323 Calls and Multicast Conferencing earlier in this chapter.

Video problems in NetMeeting

  • If your video capture device fails to preview video, verify that the correct display codec is selected for your video device. Select Tools/Options from the NetMeeting menu bar, select the Video tab, then click Source to view the codec selected for the current session. Select the correct codec, then close and restart NetMeeting.

  • If another application is using the same video device selected for your NetMeeting video conference, the video functions in NetMeeting might be disabled. Select another video device or close the other application.

  • If you are using the video capture functions in a dark area, some cameras cause the session to become extremely slow and unresponsive. Some video drivers provide a low-light filter option. Enable the option if available.
