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 measurementsType Event Description Measurements - thresholdsNetwork Network Send

QualityPacket loss and jitter on receive stream is severe and introducing distortion

Jitter - Good <20ms, Bad >30msPacket 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

10

Call Quality Notifications (Cont’d)Events and measurements

Type Event Description Measurements - thresholdsDevice Echo Device or setup is causing echo beyond the ability of the

system to compensateTimestamp noiseDynamic and Adaptive NLP attenuationPost-AEC echo percentageMicrophone 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 one-way 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 SNRHigh 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 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 detected in the same session, system compensates by reducing render volume

Detect conference join tone in the room

• Easily enable call routing so that calls reach you

• Take your calls with you wherever you are

New Features• Top-level device selection

• In-call device “hot-swapping”

• Endpoint transfer to mobile phone

Phone Calls Where You Want Them

Easy control of calls and devices

17

Pre-call Device SelectionAutomatic 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

19

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

Call

Henriette and Paul are in a call

Henriette uses Lync 2010 to transfer the call to her mobile phone

1. Lync 2010 sends an audio invite to Mediation server

2. Mediation server calls through PSTN to Henriette’s mobile phone

3. Henriette answers; she now has two calls

4. Lync 2010 asks Mediation server to connect Paul to the mobile call

5. Mediation server sends a SIP INVITE with REPLACE to Paul

6. Paul is connected to Henriette’s mobile without Paul noticing; Henriette’s call between Lync 2010 and her mobile phone ends automatically
