Command Reference Guide
ip rtp quality-monitoring
Use the ip rtp quality-monitoring command to globally enable voice quality monitoring (VQM) of the
Realtime Transport Protocol (RTP) voice stream packets. Use the no form of this command to disable
VQM. Variations of this command include:
ip rtp quality-monitoring
ip rtp quality-monitoring scoring-adjustment japan
ip rtp quality-monitoring sip
ip rtp quality-monitoring udp
Syntax Description
scoring-adjustment japan
sip
udp
Default Values
By default, the VQM is disabled globally.
Functional Notes
Disabling VQM on the global level (for example, to change the scoring adjustment) erases all active calls,
new calls, and interface statistics. Call history and endpoint statistics are not affected.
If the sip or udp parameters are specified, and VQM has not previously been enabled at the global level,
VQM will be enabled globally. Enabling UDP packet inspection forces the AOS unit to inspect every UDP
packet to determine if it is an RTP packet, placing a significant load on the AOS unit. UDP packet
inspection should only be enabled if IP phones are being used and they do not pass through the SIP ALG,
SIP proxy, or SIP B2BUA.
For more information about VQM configuration, refer to the configuration guide Configuring VQM in AOS

Usage Examples
The following example enables RTP quality monitoring at the global level and does not specify a scoring
region or RTP signaling type:
(config)#ip rtp quality-monitoring
60000CRG0-35E
Optional. Sets the region for scoring adjustment for Japan. In Japan, the
mean opinion score (MOS) statistics are calculated differently than in
other regions. VQM must be disabled and then enabled again for this
setting to take effect.
Optional. Specifies that Session Initiation Protocol (SIP) is the signaling
type of the RTP stream to monitor.
Optional. Specifies that User Datagram Protocol (UDP) is the signaling
type of the RTP stream to monitor.
