configure MOS thresholds on a per-codec basis; alerts are sent to an upstream application
such as Cisco Unified Operations Manager when an MOS threshold is violated. It allows
users to identify the endpoints that are most affected by voice-quality issues and
understand the service-quality experience at a system level.
Cisco 1040 Sensor voice-quality measurement capability can be used in Cisco Unified
CallManager, 3.3, 4.0, 4.1, and 4.2, and Cisco Unified Communications Manager 4.3, 5.0, 5.1, 6.0
and 6.1 and Cisco Unified Communications Manager Express environments to measure voice
quality for active calls made between a Cisco Unified IP phone and another Cisco Unified IP phone
or voice gateway or voicemail system. While Cisco 1040 Sensors provide near-real-time voice-
quality measurement for active voice calls made from an IP phone to another IP phone or voice
gateway or voicemail system, Cisco Voice Transmission Quality (VTQ) support in Cisco Unified
CallManager 4.2 and Cisco Unified Communications Manager 4.3, 5.0, 5.1 or higher environments
provides continuous voice-quality measurement for calls made from all endpoints (Cisco Unified IP
Phones 794x, 796x, or 797x) that support VTQ. VTQ is an endpoint MOS estimation algorithm as
described in the ITU P.564 standard. The VTQ score represents weighted estimate of “average
user” annoyance caused by effective packet loss. The combination of Cisco 1040 Sensor
functionality and VTQ support provides comprehensive voice-quality measurement capability to
monitor key Cisco Unified IP phones (for example, for executives or critical users) in real time and
to track voice quality for all the calls in the system.
Applications
Deployments of up to 5000 Phones
For deployments of up to 5000 phones (Figure 1), Cisco Unified Service Monitor (Cisco USM)
2.0.1, Cisco Unified Operations Manager (Cisco UOM) 2.0.3, and Cisco Unified Service Statistics
Manager (Cisco USSM) 1.0 may be deployed on the same Windows 2003 server. A single
installation process installs all the necessary components.
