The Echo Cancellation check box defines whether echo

cancellation is enabled, the MultiVOIP 400/800 will remove
echo-delay which improves the quality of sound.
The Forward Error Correction (FEC) check box defines
whether forward error correction is enabled for this voice
channel. The FEC feature allows some of the voice
