DT_ ACOUSTIC_DEV_THRESHOLD
This field defines the instantaneous acoustic power change that is deemed to correspond to speech and is used to detect short term
changes in voice level on the acoustic interface.Raising (lowering) this field will raise (lower) the change in acoustic power required for
the detection of speech (and hence the double talk condition).

VD_LONG_NETWORK_ATTACK_TC
Network long term power estimation’s attacking time constant
This field defines the inertial delay utilized for the long term network power estimation. Raising the value of this field reduces the inertia
and will make the estimation more responsive whilst lowering the field will cause the power estimation algorithm to be less responsive to
bursts of energy on the network side.
