Enabling Silence Compression on a DSP Channel
You can enable silence compression on a DSP channel to reduce the number of sent voice
packets.
Context
To save network bandwidth, enable silence compression on a DSP channel. When no voice is
detected, the encoder generates short silence codes, but does not generate voice compression
codes. In addition, the encoder notifies the receiver of silence start until the voice is restored.
The silence compression function reduces the number of sent voice packets.
