sound levels

When two sounds are added together, the volume increases. Limits must be set so that the total volume level (measured in dBm) does not exceed the allowed maximum on a telephone channel. Background music uses the system variables and system parameters described here to control these levels.

Background music uses the system variables and system parameters shown in Table 1 to control these levels.

Table 1. System variables and parameters used for background music..
This table describes the system variables and system parameters used to control the total volume level of background music. The parameter group is also listed for each parameter.
System Variable	System Parameter ¹	Parameter Group
SV223 System : Prompt volume ceiling	Prompt Volume Ceiling Default	Trunk Interface
SV224 System : Music : Volume ceiling	Music Volume Ceiling Default	Trunk Interface
SV225 System : Music : Automatic fade time	Music Automatic Fade Time Default	Application Server Interface
SV226 System : Music : Automatic fade before actions	Music Automatic Fade Before Actions	Application Server Interface
	Music Channels Maximum	Trunk Interface
	Music Absolute Silence Threshold	Trunk Interface
For details of system parameters, see the Blueworx Voice Response for AIX: Configuring the System information.

To reset the value of a system parameter: Welcome window —> Configuration —> System Configuration —> Change —> open the parameter group —> open the system parameter —> click or type in the new value —> OK. Before closing the System Configuration window, you need to Save the new value.

Each system parameter has help information which is also listed, in alphabetical order, in the Blueworx Voice Response for AIX: Configuring the System information.
