CONCURRENT LOAD
Runs a bulk transfer alongside the probe — spikes usually appear only when the line is busy.
The test connects automatically and disconnects when it finishes. You can run 2 tests per day; you'll get a quick “I'm human” check the first time.

PACKET-DELAY-VARIATION SUMMARY

JITTER-BUFFER SIMULATION · discards → MOS
| Buffer depth | Late / discarded | Effective loss | Added delay | MOS · G.711 | MOS · Opus | MOS · G.729 | Verdict |
|---|
A packet that arrives later than the buffer depth is discarded — that is a mid-call dropout. Deeper buffers discard fewer packets but add mouth-to-ear delay, which also degrades the call. The best depth is the one with the highest MOS. Figures are round-trip PDV (conservative — both directions’ jitter counted).
06
FULL-RUN EXCURSION TIMELINE
Every packet’s excursion across the whole run. Horizontal lines are jitter-buffer depths — points above a line are discards at that depth. Look for a repeating pattern: periodic spikes usually fingerprint a specific cause.
