Cisco Unified Communications

Cisco ® Unified Communications Solutions unify voice, video, data, and mobile applications on fixed and mobile networks, enabling easy collaboration every time from any workspace.

Product Overview

Cisco 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 (refer to 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 (for example, phones and gateways) that are most frequently affected by voice-quality issues. The reports allows users to understand service quality at a system level through call-quality metrics gathered from Cisco Voice Transmission Quality (VTQ) functionality. The reports provide information about real-time service quality through Cisco 1040 Sensors and Cisco Network Analysis Module 4.0. The enhanced call stream correlation report (Figure 2) provides detailed call metrics collected from multiple instances of Cisco 1040 Sensors and Cisco Network Analysis Module, which will enable 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 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 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.

Cisco Network Analysis Module

The Cisco Network Analysis Module Family of products offers unparalleled 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 4.0. For details, visit:
