Call End
100 (Non sustainable) reported in the following cases:
(1)· 'Silent Call' TCC event was reported for completed call (detected by the AQM algorithm, all system signaling was ok, but audio was not transferred in both directions)
(2) 2 consecutive low quality speech samples (regardless of call direction) are detected in the course of a call.
...
0 (Sustainable) reported in all other cases.
...
SWB speech quality is checked against LowSuperwidebandScoreThreshold UDP, while NB against LowNarrowbandScoreThreshold UDP.
