Cisco Unified Communications
® Unified Communications Solutions unify voice, video, data, and mobile applications on fixed and mobile networks, facilitating easy collaboration every time from any workspace. Part of a comprehensive solution that includes network infrastructure, security, wireless, management, or third-party applications and lifecycle services, Cisco Unified Communications management solutions can accelerate deployment, provide cost savings, and enhance productivity.
Cisco Unified Service Monitor (USM) 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 (refer to Figure 1). In addition to voice-quality monitoring, Cisco Unified Service Monitor allows you to perform call classification based on dial plan. The on-demand call-detail-record (CDR) reports allow you to view the call records for call analysis.
Figure 1. Cisco Unified Service Monitor: Voice Transmission Quality and Most Impacted Endpoints Report
Cisco Unified Service Monitor monitors, evaluates, and generates reports about 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 problems.
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 Network Analysis Module, which will allow system administrators to idenitfy network segments that have a lower-quality user experience.

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 the Cisco Network Analysis Module. Threshold-based alerts are sent to upstream applications such as Cisco Unified Operations Manager or a manager-of-managers application.
Cisco Unified Service Monitor allows you to set thresholds based on device types and codec types, incorporates support for Cisco Unified Communications Manager 8.5, and includes reporting data export. Alerts are sent to upstream applications such as Cisco Unified Operations Manager when a MOS threshold is violated.
Cisco Unified Service Monitor 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 their deployment. Cisco Unified Service Monitor 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.
Integration with Cisco Unified Operations Manager
Integration with Cisco Unified Operations Manager allows you to send near real-time alerts through Simple Network Management Protocol (SNMP) traps, email, paging, and syslog messages to notify administrators of call-quality degradation. Cisco Unified Operations Manager also allows you 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 problems that result in user-experience degradation. For more information, please visit
Integration with Cisco Unified Service Statistics Manager
Integration with Cisco Unified Service Statistics Manager provides long-term statistics analysis and reports for Cisco Unified Communications networks. Using the data collected by Cisco Unified Operations Manager and Cisco Unified Service Monitor, Cisco Unified Service Statistics Manager provides predefined and customizable reports that give visibility into critical metrics, including call volume, service availability, call quality, resource usage, and capacity across the Cisco Unified Communications system. For more information, please visit:
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, is a shelf-top unit that connects to the network and obtains Power over Ethernet (PoE) through a Cisco Catalyst
Figure 3. Cisco 1040 Sensor
Cisco Network Analysis Module
The Cisco Network Analysis Module Family of products offers superior visibility into application and network performance to help ensure consistent and efficient delivery of applications and services to end users. The family includes both integrated service modules and self-contained appliances offering deployment flexibility essential for managing application performance and improving operational manageability of the underlying network. Figure 4 shows the Cisco Network Analysis Module. For more information, please visit:
