Output attenuation
Слайд 7Echo Cancellation
Echo cancellation is configured at the voice port level.
Echo
cancellation is enabled by default.
Echo cancellation coverage adjusts the size of the echo canceller.
Nonlinear echo cancellation shuts off any signal if near-end speech is detected.

Слайд 8Summary
Voice quality is affected by the settings on each voice port.
Factors that affect voice quality include transmit and receive power levels, input gain, and output attenuation.
Input and output power levels must be configured to match the connected devices.
If the impedance is set incorrectly (if there is an impedance mismatch), a significant amount of echo is generated. Impedance settings must match the connecting equipment.
To eliminate echo on a voice call, you can configure echo cancellation using the echo-cancel enable, echo-cancel coverage, and non-linear commands.
