The echo cancellation NLP threshold level.
0 : Strongest echo cancellation, weakest double-talk detection.
4 : Weakest echo cancellation, strongest double-talk detection.
Increase the value if cuts in the voice stream are present, decrease it if too
much echo can be heard.
This variable's semantics are different depending on protocol and/or hardware
platforms. Please refer to the documentation for more details.
This object is deprecated. Agents may or may not implement it.
