7 If the echo still exists, set the EC Configuration: field to 2, 3, or 4, then test the voice
quality. These settings provide help for the following scenarios:
• Setting 2 – Minimizes speech clipping, but it takes a fraction of a second longer for the
echo to fade.
• Setting 3 – Eliminates speech clipping, but a strong echo may take 2 or 3 seconds to fade.
• Setting 4 – Minimizes extremely strong echo, very hot signals, or excessive clipping or
breakup of speech from a distant party. It reduces speech clipping but may allow slight
residual echo or more background noise.
8 If the echo still exists after trying every previous setting, contact technical support.
