The system generates user-experience reports that provide lists and details of the endpoints (for example, phones
and gateways) that are most frequently affected by voice-quality problems. The reports allow you to understand
service quality at a system level through call-quality metrics gathered from Cisco Voice Transmission Quality
(VTQ) functions. The reports provide information about real-time service quality through Cisco 1040 Sensors and
the Cisco Network Analysis Module (NAM) 4.0 and later. The enhanced call-stream correlation report (Figure 2)
provides detailed call metrics collected from multiple instances of Cisco 1040 Sensors and the Cisco NAM, which
will allow system administrators to identify network segments that have a lower-quality user experience.

Features and Benefits
Voice-Quality Measurements and Alerts
USM monitors voice-quality measurements in a voice-over-IP (VoIP) network and produces alerts based on
measurements exceeding preset thresholds. Key voice-call characteristics such as codec type, jitter, and packet
loss are collected and reported.
The phone-based Cisco VTQ solution provides user-experience metrics at the end of all active calls in the
network, expressed as a Mean Opinion Score (MOS) calculated value. Real-time MOS values can be produced
every 60 seconds for monitored active calls using Cisco 1040 Sensors and the Cisco NAM. Threshold-based
alerts are sent to upstream applications such as Cisco Prime Unified Operations Manager or a manager-of-
managers application.
Thresholds
USM allows you to set MOS thresholds based on the phone codec types and includes reporting data export. Alerts
are sent to Cisco Prime Unified Operations Manager or any Simple Network Management Protocol (SNMP)
manager when a MOS threshold is violated.
Call Classification
USM allows you to classify calls based on dial plan per cluster. Call classification has default system-defined call
categories and also allows you to define call categories to suit the deployment. USM can classify calls to multiple
categories to help ensure that users can track calls based on call types. The on-demand CDR reports provide a
rich set of filters to generate important call information to facilitate detailed analysis.
