Silence 
Compression
 
Y/N 
Determines whether silence 
compression is enabled (checked) for 
this voice channel.   
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.   
Default = on.
 
Echo 
Cancellation 
Y/N 
Determines whether echo cancellation is 
enabled (checked) for this voice 
channel.  
Echo Cancellation removes echo and 
improves sound quality.  Default = on.
 
Forward 
Error 
Correction 
Y/N 
Determines whether forward error 
correction is enabled (checked) for this 
voice channel.  
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
