This report evaluates seven key metrics—Packet Jitter Average and Max, Packet Loss, Packet Delay, Network Capacity, SIP ALG, and the overall MOS score for both incoming and outgoing calls—by analyzing both average and peak values. It identifies performance issues and offers corrective recommendations. The summary table categorizes results as Good, Fair, or Bad, and resolving issues rated as Fair or Bad is strongly advised to ensure a high-quality VoIP experience.

Jitter measures the variability in the arrival times of VoIP packets, expressed in milliseconds. On an ideal connection, packets sent 20ms apart would also arrive 20ms apart, resulting in zero jitter. If the packets arrive 21ms apart, 1ms of jitter is recorded. High jitter negatively impacts VoIP quality because it depletes the jitter buffer; when the buffer empties, late-arriving packets are discarded, causing voice quality to deteriorate.

This capacity test is designed to confirm that an active connection can reach and sustain the necessary bandwidth while consistently delivering media data at the service levels required for VoIP and other media applications, such as conferencing and collaboration. It evaluates key performance factors like packet loss, buffer saturation, and jitter.

This traceroute assessment maps the network path between your source and destination, revealing the latency and performance at each hop. It provides a detailed view of the route taken by packets, helping to identify potential delays or bottlenecks. Note that values that are yellow typically indicate hops that did not respond to the ping; these are common occurrences and are not necessarily indicators of a problematic trace.
