l Lync client supporting this enhancement sends an InCallQuality message every 35 seconds (by default).
Lesser messages are sent for stable VoIP calls.
l InCallQuality message provides cumulative values of call quality metrics like delay, jitter, packet loss, MOS,
and more while the VoIP call is active.
l In a good call quality, the controller receives only a single InCallQuality message after the first period. No
further InCallQuality messages are sent until the end of call QualityUpdate message.
l If the call quality fluctuates and crosses the threshold, these events are collected and the sent message is
delayed until the least period of time has passed since the last InCallQuality message is sent.
