Silence
Compression
SC “SC” stands for Silence Compression. With Silence Compression
enabled, the MultiVOIP will not transmit voice packets when
silence is detected, thereby reducing the amount of network
bandwidth that is being used by the voice channel.
FEC “FEC” stands for Forward Error Correction. Forward Error
Correction
enables some of the voice packets that were corrupted
or lost to be recovered. FEC adds an additional 50% overhead to
the total network bandwidth consumed by the voice channel.
Default = Off
