Streaming > Audio
On the Audio page, administrators can select the transmission mode and bit rate for audio
streams.
To configure audio settings
1 On the Streaming tab, click Audio in the menu on the left.
2 Under Transmission Mode, select one of the following options:
- Full-duplex – Audio can be transmitted and received at the same time, so local and
remote sites can communicate with each other simultaneously.
- Half-duplex – Audio can be either transmitted or received, so one site can talk or listen to
the other site in turn.
- Simplex (Talk only) – Audio can be transmitted, so one site can speak to the other site.
- Simplex (Listen only) – Audio can be received, so one site can listen to the other site.
- Disable – The audio transmission function is turned off.
3 Under Server Gain Setting, select audio input/output gain levels for sound amplification.
Audio input gain is adjustable from 1 to 10. Audio output gain ranges from 1 to 6. Set
the audio gain to Mute to turn off the sound.
4 On the Bit Rate list, select the audio transmission bit rate.
Audio transmission bit rates include the following options:
- 16 kbps (G.726)
- 24 kbps (G.726)
- 32 kbps (G.726)
- 40 kbps (G.726)
- µ-LAW (64 kbps) (G.711)
- A-LAW (64 kbps) (G.711)
- AAC
- PCM (128/256/384/768 Kbps)
Both µ-LAW and A-LAW imply 64 kbps. However, µ-LAW and A-LAW use different
compression formats.
