A Better Way to Monitor Cisco's VoIP Systems
Voice traffic traverses your entire infrastructure, including routers, switches, IP telephony servers, IP phones, and circuits. Service quality can be disrupted if any of these key components are malfunctioning or misconfigured. That's why it's critical that you have proactive visibility into service quality with understandable, useful, and actionable information.
NetMRI takes the work and risk out of voice management by automating data collection and correlation of both voice data from Cisco CallManager and network data. Using expert and best-practice "rules," NetMRI analyzes your network daily-or on an ad hoc basis, whenever you want-to search for vulnerabilities and identify problems prior to any real interruption to your voice services.
The NetMRI IP Telephony Module for Cisco is the most comprehensive, automated network diagnostic tool in the industry, identifying and analyzing problems with VoIP applications.
Automate Voice Data Collection and Correlation
Customers rely on NetMRI's expert analysis and in-depth data collection to alert them of problems in their voice delivery before they can impact any end user. NetMRI employs a high-level scorecard to deliver daily data collection and expert analysis in a clear, graphic report that makes immediate sense. You see trouble spots before the network does, and that gives you the power to prevent any voice services issues.
NetMRI also offers a "Path Diagnostic" diagram that visually shows every network element in the voice connection-end to end-to highlight any disruptions in the transmission.
Integrated Analysis of Call Data Records (CDRs) and IP Infrastructure
The NetMRI IP Telephony Technology Module gathers Voice Call Detail Records (CDRs) from leading IP PBX manufacturer, Cisco. NetMRI analyzes those records on a daily or more frequent basis and creates a Path Diagnostic Chart. Call information and call performance-together with IP network analysis-provide an excellent overview of VoIP processing throughout your network and can be used to help troubleshoot specific VoIP problems.
Detect Quality of Service (QoS) Configuration Issues
NetMRI uses SNMP to capture the MIB data from all of the devices in the call path, evaluating the QoS configurations. If a given Voice Path does not have QoS configured or if the configurations change, an issue is generated to alert the engineer or technician. NetMRI collects configuration information, as well as MIB data, from key infrastructure components, including routers, switches, and some VoIP-enabled devices. Integrated with the CDR information, NetMRI then identifies hard-to-find issues, wherever they may occur, which can negatively affect QoS.
Daily Voice Assessment via High-Level Scorecard
On a daily basis NetMRI prepares a summary Network Scorecard of the network's health, with a single overall index between 0-10. VoIP is one of the key functional areas that is evaluated, measuring Correctness and Stability based upon Cisco's and other leading manufacturers' best practices.
Detailed Analysis of Voice Data Across the Network
In addition to identifying VoIP issues and helping technicians troubleshoot specific problems, NetMRI provides summary tables and charts for a management overview of how VoIP is being used across the network.
Leverage Cisco IP SLA To Further Ensure Call Qualify
NetMRI supports Cisco's IP Service Level Agreements (SLAs), a standard feature supported by most Cisco routers and switches. IP SLA generates representative synthetic traffic, replicating VoIP traffic on the network between selected Source and Destination nodes. NetMRI then measures latency, jitter, and dropped packets, which are the key metrics to maintaining VoIP quality of service.
NetMRI shows you the cause of poor voice quality, not just the symptoms. Your voice services will have the highest performance because NetMRI audits every device, every phone, and every call record to detect problems proactively.
