DCS over IP Trunk

Changing Audio Settings

F IP Trunk Installation and

Administration

To change the audio settings so that NetMeeting operates properly with the IP trunk application, follow these steps.

1From the Tools menu choose Options and then select the Audio tab. The Audio tab settings appear as shown in Figure 5.

Figure 11. Audio Tab Settings in Options Dialog Box

2Click the check box for Enable full duplex audio so I can speak while receiving audio.

If this option is dimmed, it is not accessible to change. This means your sound card is not full duplex. You need to install updated sound card drivers to make the card full duplex.

3Click the check box for Use H.323 gateway and type the IP address of the IP trunk in the corresponding field.

4In the same Options window, select the Calling tab and clear the Refresh directory listing check box.

5Click OK to save your changes and close the Options dialog box.
