Silence suppression and comfort noise generation
Note:
Software version 1.6.1 is required to support silence
suppression and comfort noise generation on voice over ATM calls.
Silence suppression detects and removes silence in a call, reducing the
required bandwidth for the call, and thus increasing the number of calls
carried on the same connection. One drawback of silence-suppressed voice
compression is the lack of ambience, or background noise, during silent
periods of phone conversations. Comfort noise generation adds background
noise on the receiving side of the call which has been encoded with silence
suppression.
