Check the box to enable Full Duplex mode. This means that
you can transmit and receive audio (talk and listen) at the same time, without having to use
any of the controls. This is just like having a telephone conversation. This mode requires
that the client PC has a sound card with support for full-duplex audio.
Uncheck the box to enable Simplex mode. The simplex mode only transmits audio from
the network camera to any web client. It does not receive audio from other web clients.
