NetMeeting provides full audio capabilities. The audio feature supports microphones, speakers, and telephones.
If you are using a microphone and speakers, your audio can be either half-duplex or full-duplex. Half-duplex audio allows one person to speak at a time. Full-duplex audio allows two people to speak simultaneously. Check with the sound card manufacturer to determine your sound card capabilities.
If your company has an audio gateway that you use to place calls, you can use your telephone instead of a microphone and speakers. For more information on audio gateways, contact your system administrator.
