VoIP Use Today 
Today’s networks and application delivery mechanisms are extremely sophisticated, with an intricate interdependence of diverse, multi-vendor infrastructure components and technologies. Adding real-time, delay-sensitive voice applications to the delay-tolerant IP environment complicates your effort to manage the performance of the network, mission-critical applications, and user-expectations of voice service quality. In a converged environment it is necessary to view and manage VoIP (Voice over IP) and business applications together in order to analyze how they impact one another.

Managing VoIP Effectively 
The NetScout Solution provides the means to optimize the delivery and ensure the peaceful co-existence of voice and business-critical applications across the IP infrastructure. You can manage the performance of your VoIP, including Avaya or Cisco implementations, through its lifecycle using key functionality, for network monitoring, capacity planning, network troubleshooting and response time analysis, and carry out comprehensive pre-deployment network and application analysis, understand the real-time impact of their VoIP installation, manage and troubleshoot ongoing performance, and report results.

  • Optimize delivery of VoIP services by viewing voice-specific metrics on utilization, phone users, conversations, configuration, and quality, plus continuous packet-level recording for voice call playback
  • Gain a business perspective of network details using the richest visibility into the application traffic in your enterprise, including response, utilization trends, and conversation metrics, helping you justify decisions about your time, budget, and policies
  • Quickly troubleshoot network problems and reduce mean time to repair (MTTR) by monitoring and resolving any issues in your converged network, thereby minimizing business impact before, during and after your VoIP deployment. With the nGenius top-down approach, context-sensitive drill-downs and unique Workspaces, you can correlate all key data sets needed to fix a performance problem and speed troubleshooting
  • Proactively manage bandwidth growth by forecasting network and application growth and identifying areas in the network with too little capacity so that you may ensure continued availability and quality of networked voice and data services
  • Verify QoS configuration by tracking traffic by QoS class to verify the prioritization of your VoIP services, plan changes to QoS policies, and rapidly troubleshoot any QoS misconfigurations

Support for Cisco and Avaya VoIP Implementations 
In addition to supporting standards based voice and call set up protocols such as RTP, RTCP, MGCP, SIP, and H.323, the nGenius VoIP management solution also supports Cisco implementations using the SCCP call set up protocol, and Avaya's Extended H.323 call set protocol that appears as Q.931 in the NetScout Solution.
