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
