HD Audio
This is the default mode and should be used unless there is a good reason (for example limited bandwidth) to not use it.
In this mode Exigo is sending pure Linear PCM 16-bit 48 KHz sampled audio over RTP.
For background music this mode is also recommended.
The network bandwidth for HD Audio is approximately 800 kbit/s (per stream).
Voice
In this mode the device uses the G.722 codec.
G.722 is also used for all pre-recorded messaging, alarm, live speech etc.
Voice mode can be used when bandwidth use should be limited.
Availability
This function is available on Exigo 1.3.3 and newer.
