tunneling (Tun), Fast Start with tunneling (FS + Tun), Annex E multiplexed UDP
call signaling transport (AE), and Q.931 Multiplexing (Mux).
Silence Compression
SC
“SC” stands for Silence Compression. With Silence Compression enabled, the
MultiVOIP does 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. Default = Off
