Interaction Media Server Technical Reference
Conference call features
Conference calls that Interaction Media Server hosts include features such as dominant speaker detection with echo cancellation (muting errant noises from other callers), automatic level control (volume), support for Interactive Voice Response (IVR) input, and other optimizations.
Note: In Interaction Administrator, use the Optimize Audio for Conferences list box on the Telephony Parameters tab of the Server Configuration dialog box to control dominant speaker detection globally with echo cancellation for conference calls.
If you experience audio issues when you enable Optimize Audio for Conferences, you can specify the ConferenceTypeDominantSpeakerDiagnosticRecording property through the Media Servers container in Interaction Administrator and set the value to true. This property creates diagnostic recordings that you can send to a PureConnect Customer Care representative for analysis.
