Parameter
Permitted Values
Default
voice.qualityMonitoring.collector.enable.triggeredPeriodic
1
0 to 2
0
If 0, alert states do not cause periodic reports to be generated. If 1, periodic reports are generated if an alert state
is critical. If 2, period reports are generated when an alert state is either warning or critical. Note: This parameter
is ignored when voice.qualityMonitoring.collector.enable.periodic is 1, since reports are sent
throughout the duration of a call.
voice.qualityMonitoring.collector.period
1
5 to 20
20
The time interval between successive periodic quality reports.
voice.qualityMonitoring.collector.server.x.address
1
The server address
voice.qualityMonitoring.collector.server.x.port
1
The server port.
Dotted-decimal IP
address or
hostname
1 to 65535
Null
5060
The server address and port of a SIP server (report collector) that accepts voice quality reports contained in SIP
PUBLISH messages. Set x to 1 as only one report collector is supported at this time.
voice.qualityMonitoring.rtcpxr.enable
1
0 or 1
0
If 0, RTCP-XR packets are not generated. If 1, the packets are generated.
1
Change causes phone to restart or reboot.
<rxQoS/>
The following table lists the jitter buffer parameters for wired network interface voice traffic, wireless
network interface voice traffic, and push-to-talk interface voice traffic.
Voice Jitter Buffer Parameters
Parameter
Permitted Values
Default
voice.rxQoS.avgJitter
1
The typical average jitter.
voice.rxQoS.maxJitter
1
The maximum expected jitter.
0 to 80
0 to 200
20
160
The average and maximum jitter in milliseconds for wired network interface voice traffic.
avgJitter – The wired interface minimum depth will be automatically configured to adaptively handle this level
of continuous jitter without packet loss.
maxJitter – The wired interface jitter buffer maximum depth will be automatically configured to handle this
level of intermittent jitter without packet loss.
Actual jitter above the average but below the maximum may result in delayed audio play out while the jitter buffer
adapts, but no packets will be lost. Actual jitter above the maximum value will always result in packet loss. Note
that if legacy voice.audioProfile.x.jitterBuffer.* parameters are explicitly specified, they will be
used to configure the jitter buffer and these voice.rxQoS parameters will be ignored.
