Enable full duplex:
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 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.
