AudioStream Table

 

Topic Last Modified: 2010-12-14

Each record represents one audio stream. One audio media line usually contains two audio streams.

 

Column Data Type Key/Index Details

ConferenceDateTime

Datetime

primary

Referenced from the MediaLine Table.

SessionSeq

Int

primary

Referenced from the MediaLine Table.

MediaLineLabel

tinyint

primary

Referenced from the MediaLine Table.

StreamID

int

primary

Unique ID within a media line.

JitterInterArrival

Int

 

Average network jitter from Real Time Control Protocol (RTCP) statistics.

JitterInterArrivalMax

Int

 

Maximum network jitter during the call.

PacketLossRate

decimal(5,4)

 

Average packet loss rate during the call.

PacketLossRateMax

decimal(5,4)

 

Maximum packet loss observed during the call.

BurstDensity

decimal(9,4)

 

Average density of packet Loss during bursts of losses during the call.

BurstDuration

Int

 

Average duration of packet loss during bursts of losses during the call.

BurstGapDensity

decimal(9,4)

 

Average density of packet loss during gaps between bursts of packet loss.

BurstGapDuration

Int

 

Average duration of gaps between bursts of packet loss.

PacketUtilization

Int

 

Packet count for the audio stream.

BandwidthEst

Int

 

Bandwidth estimates for the audio stream.

DegradationAvg

decimal(3,2)

 

Network MOS Degradation for the whole call. Range is 0.0 to 5.0. This metric shows the amount the Network MOS was reduced because of jitter and packet loss. For acceptable quality it should less than 0.5.

DegradationMax

decimal(3,2)

 

Maximum Network MOS degradation during the call.

DegradationJitterAvg

decimal(3,2)

 

Network MOS degradation caused by jitter.

DegradationPacketLossAvg

decimal(3,2)

 

Network MOS degradation caused by packet loss.

AudioPayloadDescription

int

Foreign

The audio Codec used for the call, referenced from PayloadDescription Table.

AudioSampleRate

int

 

Sampling rate for the audio stream.

RoundTrip

int

 

Round trip time from RTCP statistics. For acceptable quality this should be less than 100ms.

RoundTripMax

int

 

Maximum round trip time for the audio stream.

OverallAvgNetworkMOS

decimal(3,2)

 

Average wideband Network MOS for the call. This metric depends on the packet loss, jitter, and codec used. Range is [1.0 to 5.0].

OverallMinNetworkMOS

decimal(3,2)

 

The minimum wideband Network MOS for the call.

SendListenMOS

decimal(3,2)

 

The average predicted wideband Listening MOS score for audio sent, including speech level, noise level and capture device characteristics.

SendListenMOSMin

decimal(3,2)

 

The minimum SendListenMOS for the call.

RecvListenMOS

decimal(3,2)

 

The average predicted wideband Listening MOS score for audio received from the network including speech level, noise level, codec, network conditions and capture device characteristics.

RecvListenMOSMin

decimal(3,2)

 

The minimum RecvListenMOS for the call.

AudioFECUsed

bit

Flag indicating if audio FEC was used for the call.

RatioConcealedSamplesAvg

Decimal(5,2)

Average ratio of concealed samples generated by audio healing to typical samples.

RatioStretchedSamplesAvg

Decimal(5,2)

Average ratio of stretched samples generated by audio healing to typical samples.

RatioCompressedSamplesAvg

Decimal(5,2)

Average ratio of compressed samples generated by audio healing to typical samples.

Inbound

bit

 

Stream data on receiver side is received.

Outbound

bit

 

Stream data on sender side is received.

SenderIsCallerPAI

bit

 

1 means the stream direction is from the caller to the callee.

0 means the stream direction is from the callee to the caller.
