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.
Forward Error
Correction
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.
