Off simply disables the headset.
Internal mode only distributes the talk back audio
in the local mesh network.
Remote mode allows the onward distribution of this
audio on an external IP network using RTSP
protocols.
The remote mode also allows external
‘eavesdropping’ of the audio using the URL:
rtsp://ip_address_of_unit/audio.sdp
Audio can also be sent to that unit using the same
port as the RTP packet. The audio format must be
G726-32 with a payload size of 512 bytes.

An external push to talk switch can be connected
with the microphone to do the same task if required.
All NETNode units give a low level bleep tone when
no talkback is received and the unit is connected
onto the mesh network.
