9. Call Quality Notifications Overview of alert types Network – packet loss, jitter, bandwidth, latency Device – malfunctioning microphone or speaker, echo, low signal-to-noise ratio (SNR) CPU – low CPU cycles for audio encoding and decoding Events and measurements TypeEventDescriptionMeasurements - thresholds NetworkNetwork Send QualityPacket loss and jitter on receive stream is severe and introducing distortion Jitter - Good 30ms Packet Loss - Good 7% Network Receive Quality Concealed packet ratio on send stream is severe and introducing distortion Concealed Packet Ratio - Good 3% Low BandwidthAvailable bandwidth is insufficient for acceptable voice/video experience Dynamic based on codec High LatencyNetwork latency is severe and preventing interactive communication RTT - Good 500ms MachineLow CPU cycles Insufficient CPU for processing current modalities and apps, causing audio distortion Flag the event when audio encoding/decoding engine is not getting sufficient CPU cycles Remote userLow SNRPoor capture quality from remote user; distortion from noise or user being too far from microphone Flag if participant in the conference has a noisy environment EchoRemote user's device or setup is causing echo beyond the ability of the system to compensate Flag if remote user (or participant in a conference) has a device set up that is injecting echo into the call 9

10. Call Quality Notifications (Cont’d) Events and measurements TypeEventDescriptionMeasurements - thresholds DeviceEchoDevice or setup is causing echo beyond the ability of the system to compensate Timestamp noise Dynamic and Adaptive NLP attenuation Post-AEC echo percentage Microphone clipping due to far-end signal HowlingAudio feedback loop detected (caused by multiple endpoints sharing audio path) Check for howling/screeching from other endpoints in the room Capture Device Not Functioning Microphone currently used is not functioning correctly, causing one-way audio issues Check capture buffer status Render Device Not Functioning Speaker currently used is not functioning correctly, causing one- way audio issues Check render buffer status Render GlitchesSevere glitches in audio rendering, causing distortion; can be caused by driver issues, deferred procedure call (DPC) storm (drivers), high CPU usage Look for glitches after adaptive render buffer Low SNRPoor capture quality; distortion from noise or user being too far from microphone Low SNR High absolute noise level after AGC Microphone ClippingUser’s speech level is too high for the system to handle and is causing distortion Microphone clipping during near end–only portions Near End to Echo RatioUser’s speech is too low compared to the echo being captured, limits ability to interrupt a user; reduce speaker volume or move closer to microphone Near end–to-echo ratio Half Duplex ModeTo prevent echo, system enters half duplex mode (dynamic switching between render and capture streams), which limits ability to interrupt a user Flag the event when device is in "voice switch" mode Multiple Audio EndpointsMultiple audio endpoints detected in the same session, system compensates by reducing render volume Detect conference join tone in the room 10

17. Pre-call Device Selection Automatic device selection By default, Lync 2010 automatically selects the “most capable” device Multiple criteria are used to determine which device is most capable Capabilities and certification status are queried from the device itself Unified Communications (UC)–certified devices with the most functionality are selected first User can override by selecting preferred device Preferred device User can select any device as the “preferred device” from top-level menu or Audio Device options Preferred device is used for both outgoing and incoming calls “Click-to-Call” results in the preferred device being used Clicking an incoming call toast results in the preferred device being used The preferred device is persisted across all calls and sessions If preferred device is present, Lync will use it as the default Lync 2010 falls back to automatic device selection if preferred device is unplugged Lync 2010 remembers and returns to preferred device when it is plugged back in 17
