QoS metrics
The following table describes the QoS metrics on which thresholds are configured, and the
time when each metric is evaluated.
Metric
Description
Evaluation time
Codec Loss
The percentage of time the codec plays fill
frames due to lack of valid RTP frames.
Possible causes include jitter and packet
loss.
Every RTCP interval
Average Codec Loss The average codec loss measurement since
the beginning of the RTP stream
At the end of the
session
Codec RTT
An estimation of the overall Round Trip Time
(RTT) on the voice-channel, including the
network delay and internal delays.
RTT is the time taken for a message to get to
the remote peer and back to the local
receiver.
Each time an RTCP
packet is received
Echo Return Loss
The echo cancellation loss on the TDM bus
Every RTCP interval
Loss
The estimated network RTP packet loss.
The VoIP engine evaluates the current
received packet loss every RTCP interval –
usually 5 to 8 seconds. The VoIP engine
postpones loss estimation until the next
interval if the number of packets received is
less than the minimum statistic window. The
minimum statistic window is configured with
Every RTCP interval
