ICQ 8

To change ICQ's settings for video- and voice calls, go to "Menu" — "Settings" and select the "Voice and video" tab.   

If your computer only has one sound card, changes to the settings are usually not required. We recommend keeping the defaults.

If you want to enter the settings manually, then select the desired parameters in the "Audio playback device", "Audio recording device", and "Audio mixer" tabs.

If you check "Microphone gain", then the microphone will be sensitive as possible.  

Check "Automatic adjustment of audio settings" to avoid manual configuration of audio settings.

Webcam

If you have more than one webcam, you can select the default camera in the dropdown list.

If you check "Allow other users to find me based on webcam availability", then other uses will be able to find you, no only by standard properties (name, city, date of birth, etc.), but also by the fact that you have a webcam.

USB phone

If you have a USB phone that you want to use to talk through ICQ, check "Enable USB phone support" and select a ringtone in the dropdown list.
