2.9.3 M1x66_ThresholdOverride
Description
Various FXO channel parameters are conveniently grouped and predefined in the default country
parameter. These parameters are programmed during channel initialization API (M1x66_InitChannel).
However, these parameters can be overridden at runtime to fine tune to the desired threshold for the
specific installation using this threshold override API.
Note: This API must be invoked after the M1x66_InitChannel API to prevent the parameter from over
written.
