Conference calls
The system supports connecting participants to a conference call. Technologically, the number is not limited in any way, in practice, conferences of 3 – 10 participants at a time are recommended. Before connecting to the conference, a predefined message is played that informs the participants about the situation and then everyone is connected to the conference call.

Interactive calls
A call that recognizes the participant’s response using tone (DTMF) dialing (key presses on the phone keypad). According to the reaction of the participants, the process is then directed further by choices for successfully or unsuccessfully performed activity. You can set the number of positive responses the system should evaluate the activity as successful or unsuccessful.
