There are two modes of call processing:

  1. Duplex mode. Simultaneous translation of audio signal in “Operator - Security intercom terminal” and “Security intercom terminal - Operator” directions.
  2. Half-duplex mode. Translation of audio signal only in “Security intercom terminal - Operator” direction is enabled.

To switch over the modes, click the Space key.

Color of frame for selection the call processing in a half-duplex mode is specified on the settings panel of the Intercom Control Monitor object (see the Configure displaying the list of calls section).
