Features and Benefits
Voice-Quality Measurements and Alerts
Cisco Unified Service Monitor 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 and
characteristics, 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 Cisco Network Analysis Module. Threshold-based
alerts are sent to upstream applications such as Cisco Unified Operations Manager or a manager-of-managers
application.
Thresholds
Cisco Unified Service Monitor provides the ability to set thresholds based on device types and codec types,
incorporates support for Cisco Unified Communications Manager 7.1, and includes reporting data export. Alerts are
sent to upstream applications such as Cisco Unified Operations Manager when a MOS threshold is violated.
Integration with Cisco Unified Operations Manager
Tight integration with Cisco Unified Operations Manager offers the ability to send near real-time alerts via Simple
Network Management Protocol (SNMP) trap, email, paging, and Syslog messages to notify administrators of call
quality degradation. Ciso Unified Operations Manager also provides the ability to simulate synthetic voice traffic
using the Cisco IOS
®
Software IP service-level agreement (SLA) feature and to perform path analysis between the
devices where the endpoints are connected in order to troubleshoot network issues resulting in user-experience
degradation.
Integration with Cisco Unified Service Statistics Manager
Tight integration with Cisco Unified Service Statistics Manager offers detailed reports and analysis of the unified
communications call detail records to enable long-term trending and capacity-planning reports.
Cisco 1040 Sensors
Cisco 1040 Sensors, deployed close to the endpoint (IP phone, gateway, or voicemail system), monitor and evaluate
call quality and report this information for active calls in near real time. The Cisco 1040 Sensor, shown in Figure 3,
can be used during live subscriber calls and during synthetic test calls.
