In-band provisioning settings (Lync on-premise)Group Policy settings (Communicator 2007/R2) Single location, using a single user interfaceUse other IT groups to push GPOs Configured at the global, site, or tag level.Configured at global and user levels only Consistent for all users whether on-premise or remoteRequires corp domain connection to get policies Settings take effect immediatelyRequires Windows login to refresh settings Improved client security – users cannot modify registryMalicious user can modify registry to override policies

24. Events and Measurements TypeEventDescriptionMeasurements - Thresholds NetworkNetwork Send QualityPacket loss & jitter on receive stream is severe and introducing distortions Jitter - Good 30ms Packet Loss - Good 7% Network Receive QualityConcealed packet ratio on send stream is severe and introducing distortions 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 cyclesInsufficient CPU for processing current modalities & apps, causing audio distortions. Flag the event when audio encoding/decoding engine isn't getting sufficient CPU cycles Remote UserLow SNRPoor capture quality from remote user. Distortions from noise or user too far from mic. 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 setup that is injecting echo in the call

25. Events and Measurements TypeEventDescriptionMeasurements - Thresholds AudioEchoDevice or setup is causing echo beyond the ability of the system to compensate. Timestamp noise Dynamic & Adaptive NLP attenuation Post-AEC echo percentage Mic 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 distortions. Can be caused by driver issues, DPC storm (drivers), high CPU usage. Look for glitches after adaptive render buffer Low SNRPoor capture quality. Distortions from noise or user too far from mike.Low SNR High absolute noise level after digital AGC Microphone ClippingUser’s speech level is too high for the system to handle and is causing distortions. Microphone clipping during near end only portions Near End to Echo Ratio User’s speech is too low compared to the echo being captured, limits ability to interrupt a user. Reduce speaker volume or move closer to mic. Near-end to echo ratio Half Duplex ModeTo prevent echo, system enter 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 Endpoints Multiple audio endpoints in the same session detected and the system has compensated by reducing render volume. Detect conference join tone in the room
