Cisco Unified Communications
Cisco Unified Communications solutions unify voice, video, data, and mobile applications on fixed and mobile networks, facilitating easy collaboration every time from any workspace.
® Unified Service Monitor is a component of the Cisco Unified Communications Management Suite, consisting of Cisco
® Unified Provisioning Manager, Cisco
® Unified Operations Manager, Cisco Unified Service Monitor, and Cisco
® Unified Service Statistics Manager. Cisco Unified Service Monitor continuously monitors active calls supported by the Cisco Unified Communications system and provides near real-time notification when the voice quality of a call fails to meet a user-defined quality threshold. See Figure 1.
Figure 1. Cisco Unified Service Monitor: Voice Transmission Quality and Most Impacted Endpoint Report
Cisco Unified Service Monitor monitors, evaluates, and generates reports on user-experience metrics associated with active calls on the Cisco Unified Communications system. It provides a comprehensive list of voice-impairment metrics useful in troubleshooting voice-quality issues.
User-experience reports generated by the system provide lists and details of the endpoints (phones, gateways) that are most frequently affected by voice-quality issues. This allows users to understand service quality at a system level through call-quality metrics gathered through Cisco Voice Transmission Quality (VTQ) functionality and real-time service quality through Cisco 1040 Sensors.
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. Voice call characteristics such as codec type/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. Threshold-based alerts are sent to upstream applications such as Cisco Unified Operations Manager or a manager-of-managers application.
Cisco Unified Service Monitor provides the ability to set thresholds based on device types and codec types, incorporates support for Cisco Unified Communications Manager 6.0, and includes reporting data export. Alerts are sent to upstream applications such as Cisco Unified Operations Manager when a MOS threshold is violated. Figure 2. Integration of Cisco Unified Service Monitor

Integration with Operations Manager
Tight integration with Cisco Unified Operations Manager offers the ability to simulate synthetic voice traffic using the Cisco IOS
® Software IP service-level agreement (SLA) feature and perform path analysis between the devices where the endpoints are connected.
Integration with 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 (Figure 3), 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 Sensors can be used during live subscriber calls and during synthetic test calls.
