WildPackets' OmniPeek data-analysis tool provides an optional module, Enhanced VoIP Option, to provide VoIP analysis. OmniPeek has distributed capabilities that comprise software probes installed on remote-network subnets that report back to the main analysis engine.
OmniPeek's strength lies in the deployment flexibility of its data-capture filters - the selection criteria for catching and storing VoIP data for subsequent analysis - and the detailed level of information they supply. OmniPeek has multiple options for setting what data to capture and the VoIP conditions that cause a preset capture to begin recording data.
The precision of the filters avoids the collection of a voluminous log that could add time and overhead to the debugging process in the VoIP environment. OmniPeek allows multiple unrelated captures to execute simultaneously, with different filters and initiation conditions set on each.
One of OmniPeek's best capture-and-analysis features is the graphical Peer Map display. This shows a diagram of VoIP sessions visually with both endpoints enumerated along with visual representation depicting the relative percent of network throughput used by each session over the span of the capture. Hovering over objects in the Peer Map will generate pop-up boxes with further statistics about the object.
A unique analysis feature for captured .wav files lets an administrator replay the statistics of a captured call with the replay of the call in the same screen.
A captured call under analysis can be examined step by step as the captured metrics are synchronously displayed on the screen. If the jitter or latency degrades in midcall, the replay can be stopped, in snapshot fashion, and all associated metrics examined for insight to the call and network environment.
OmniPeek did not show as strong in real-time monitor mode. The amount of VoIP data available in real-time monitoring is limited, because standard statistics such as packet counts, network throughput percent and detected error are available only in summary aggregation by protocol. There are no drill-down capabilities to further explore issues with a particular device or IP address.
