phone status tests can be used to determine the current operational status of the IP phones in terms of signaling (SIP and SCCP) and IP
connectivity. The node-to-node tests use the services of the Cisco IP Service Level Agent (IP SLA, formerly known as Service Assurance
Agent [SAA]) in Cisco routers to simulate traffic in the network and then determine network characteristics such as reachability status,
response time, latency, jitter, packet loss, and network quality. Each of these tests can be run in a continuous monitoring mode as well as
scheduled or on-demand modes. For example, the quality of a WAN link between different sites can be tested using the node-to-node tests
and when the quality of the link drops below a certain threshold, an alert can be generated. Similarly, end-user tests can be set up that place
test calls between different sites in an automated routine. The results of these diagnostics tests are presented through a variety of reports,
and alerts can be triggered based on key thresholds being exceeded.
Service-Quality Reporting
Operations Manager 1.1 can use the information provided by Service Monitor 1.1 to present service-quality (such as quality-of-voice)
alerts on a real-time basis. The service-quality alerts are associated with IP phones or unified communications devices that are currently
monitored by Operations Manager 1.1 and present that information in the Service Quality Alerts Display. Details about IP connectivity of
the IP phones and devices are available to enable further troubleshooting. It is also possible to initiate a probable path trace between the
endpoints that helps network managers identify any potential problems in intermediate nodes that could influence service quality. Figure 5
shows service quality alerts.

Reports
Operations Manager 1.1 provides an extensive set of reports that help network managers maintain information about their Cisco Unified
Communications deployment. The historical alert, event, and service-quality reports maintain information about all the alerts and events
reported by Operations Manager 1.1 for up to 30 days. This enables network managers to document any past outage and have access to it
for long-term trending purposes. The IP phone inventory reports give network managers instant access to status information about every IP
phone deployed in the network. Extensive information on signaling details and IP connectivity details is maintained and reported. These
reports also track changes in phone status and thus serve to document move, add, and change operations on these IP phones. Such reports
are available for both SIP- and SCCP-based IP phones. The customizable reports let network managers choose what type of information
they want and create a daily report that is available by e-mail or the Operations Manager 1.1 GUI.
