This structure contains the Blueworx Voice Response system parameters that are relevant to this signaling process. The Blueworx Voice Response system parameters are configured by the system administrator using the Configuration (Pack Configurator) or Configuration (System Configuration) options of the Blueworx Voice Response user interface. These parameters are extracted from the Blueworx Voice Response system parameter database and passed to the signaling process on the SL_TRUNK_ENABLE_REQ primitive.
