This option allows you to choose whether or not ICM plays a ringing notification along with the Incoming Call Pop-up. By default this option is enabled.
To disable the Sound On feature:
From the ICM Main Window click on the Setup button.
The ICM Setup window opens with the General submenu visible:
Click the checkbox next to Sound on.
This option is now disabled and no sound will be heard as notification of an incoming call.
Note: The shorter ringing sound played when you have AutoActions defined will be played regardless of your Sound On setting. For more information, refer to AutoActions.
