Configuring MultiVOIP Slaves
12. You can enable the voice/fax advanced features by clicking
(checking) the silence compression, echo cancellation, or
forward error correction options.
The Silence Compression option defines whether silence
compression is enabled (checked) for this voice channel. If
silence compression is enabled, the MultiVOIP 200 will not
transmit voice packets when silence is detected, thereby
reducing the amount of network bandwidth that is being
used by the voice channel.
This Echo Cancellation option defines whether echo
cancellation is enabled (checked) for this voice channel. If
echo cancellation is enabled, the MultiVOIP 200 will
remove echo-delay which improves the quality of sound.
The Forward Error Correction (FEC) option defines
whether forward error correction is enabled (checked) for
this voice channel. The FEC feature allows 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.
Note: After configuring a given channel (1 or 2), you can
copy that channel's configuration by clicking the Copy
button and everything on the Voice/Fax tab will be copied
to the other channel.
