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
Type
Network
Event
Description
Measurements - thresholds
Network Send Quality
Packet loss and jitter on receive stream is severe and
introducing distortion
Jitter - Good <20ms, Bad >30ms
Packet Loss - Good <3%, Bad >7%
Network Receive
Quality
Concealed packet ratio on send stream is severe and
introducing distortion
Concealed Packet Ratio - Good <2%, Bad >3%
Low Bandwidth
Available bandwidth is insufficient for acceptable
voice/video experience
Dynamic based on codec
High Latency
Network latency is severe and preventing interactive
communication
RTT - Good <300ms, Bad >500ms
Machine
Low 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 user
Low SNR
Poor 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
Echo
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 set up that is injecting echo into the call
9
Call Quality Notifications (Cont’d)
Events and measurements
Type
Device
Event
Description
Measurements - thresholds
Echo
Device or setup is causing echo beyond the ability of the system to Timestamp noise
compensate
Dynamic and Adaptive NLP attenuation
Post-AEC echo percentage
Microphone 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
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 oneway audio issues
Check render buffer status
Render Glitches
Severe 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 SNR
Poor capture quality; distortion from noise or user being too far
from microphone
Low SNR
High absolute noise level after AGC
Microphone Clipping
User’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 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 microphone
Near end–to-echo ratio
Half Duplex Mode
To prevent echo, system enters half duplex mode (dynamic
Flag the event when device is in "voice switch"
switching between render and capture streams), which limits ability mode
to interrupt a user
Multiple Audio Endpoints Multiple audio endpoints detected in the same session, system
compensates by reducing render volume
Detect conference join tone in the room

Phone Calls Where You Want
Them
Easy control of calls and devices
UX Value Propositions
New Features
• Quickly configure and test USB • Top-level device selection
peripherals
• Improved device tuning user
• Move your calls from one device
experience
to another
• In-call device “hot-swapping”
• Easily enable call routing so that • Endpoint transfer to mobile
calls reach you
phone
• Take your calls with you wherever
you are
16
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

In-call Device Management
“Hot swapping” devices
•
New calls (in or out) initiated on the preferred device
•
User can switch devices in mid-call
•
•
Call moves immediately from one device to the other
•
Users can easily move live calls between headset/handset/speakerphone
•
Can use UI, pick up the handset desired, or push the speakerphone button
Using hot swapping device in mid-call does not change the preferred
device
•
Future calls are still initiated on the originally selected preferred device
