Fluke Networks OptiView Network Analyzer

VoIP analysis
Voice over IP is one of the most mission critical applications being deployed by IT organizations today. The rollout of VoIP services is accompanied by the expectation of toll availability and sound quality. It is therefore imperative IT organizations have the proper tools to monitor VoIP call QoS during and after implementation. OptiView Integrated Network Analyzer with the VoIP option can process a capture file and use advanced algorithms to grade the voice quality being delivered. QoS assessments are generated for each call without the need to perform detailed decoding.

"Quality Grading" thresholds can be set for key VoIP QoS parameters, such as R-Factor, Jitter, Packet Drop and Call Setup Time. The number of calls that fall within each Quality Grade is shown for key QoS parameters. Detailed VoIP call information for every call is clearly shown in a tabular view to allow quick identification of the route taken and the gateway involved, allowing you to troubleshoot quickly. As networks evolve and traffic patterns change with new applications and users, VoIP QoS can often degrade in imperceptible steps, or extreme failure. An initial VoIP deployment might run fine initially, but incremental changes to the network can slowly erode VoIP performance or completely eliminate availability. OptiView ensures visibility of VoIP performance and allows quick resolution of issues due to network growth and development.

The VoIP option provides detailed decodes of the most commonly used VoIP protocols including H.323, Cisco Skinny (SCCP), MGCP and SIP. Detailed information supports quick isolation of call setup problems. Combined with the easy-to-use single call filter and Call and Channel Table Views, call setup failures commonly caused by configuration errors, network equipment incompatibilities, or interoperability can be easily solved.

The Voice over IP Option helps you ensure Quality of Service (QoS) for this mission-critical application. And by measuring call quality at different locations on the network, IT staff can isolate network segments that need reconfiguration or upgrading.
