The Calculated Planning Impairment Factor (Icpif) of the
call that is associated to this call leg.
The value in this object is computed by the following
equation.
Icpif of the call =
Itotal (total impairment value) of the call - A
(Expectation Factor) in the cvVoIPPeerCfgExpectFactor of
the call leg associated peer.
A value of -1 implies that Icpif was not calculated and is
meaningless for this call.
