In-band provisioning settings (Lync on-premise)
Group Policy settings (Communicator 2007/R2)
Single location, using a single user interface
Use 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 remote
Requires corp domain connection to get policies
Settings take effect immediately
Requires Windows login to refresh settings
Improved client security – users cannot modify registry
Malicious user can modify registry to override policies
Note: Certain policies are still required for client bootstrapping. These are policies that take effect before the client signs in and begins receiving in-band provisioning
settings from the server.
Events and Measurements
Type
Network
Event
Network Send Quality
Description
Packet loss & jitter on receive stream is severe and
introducing distortions
Network Receive Quality Concealed packet ratio on send stream is severe and
introducing distortions
Machine
Measurements - Thresholds
Jitter - Good <20ms, Bad >30ms
Packet Loss - Good <3%, Bad >7%
Concealed Packet Ratio - Good <2%, Bad >3%
Low Bandwidth
Available bandwidth is insufficient for acceptable voice/video Dynamic based on codec
experience
High Latency
Network latency is severe and preventing interactive
communication
RTT - Good <300ms, Bad >500ms
Low CPU cycles
Insufficient CPU for processing current modalities & apps,
causing audio distortions.
Flag the event when audio encoding/decoding engine
isn't getting sufficient CPU cycles
Poor capture quality from remote user. Distortions from
noise or user too far from mic.
Flag if participant in the conference has a noisy
environment
Remote 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

Description
Measurements - Thresholds
Echo
Device 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
Howling
Audio feedback loop detected (caused by multiple endpoints sharing audio
path).
Check for howling/screeching from other
endpoints in the room
Capture Device Not 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 Glitches
Severe 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 SNR
Poor capture quality. Distortions from noise or user too far from mike.
Low SNR
High absolute noise level after digital AGC
Microphone Clipping User’s speech level is too high for the system to handle and is causing
distortions.
Near End to Echo
User’s speech is too low compared to the echo being captured, limits ability

Half Duplex Mode
To prevent echo, system enter half duplex mode (dynamic switching between Flag the event when device is in "voice
