 === Packets, jitter and MOS ===
-In the top graph you can see the packet stream (or data stream) for the specific call. The second graph holds all the information revolving packet loss and overhead packets. The third graph displays the oh so critical jitter information. Fact is, that the performance and quality of a network and its services, is dependend on multiple factors. The VoIP specific scoring algorithm called MOS, calculates a call quality grade from 0 - 5 (higher is better), based on multiple dependencies such as delay, packet loss and jitter.

The VoIP specific scoring algorithm called MOS, calculates a call quality grade from 1 (bad) - 5 (best), based on multiple dependencies such as the CODEC, its sensivity to packet loss and the actual packet loss in the network.
 In every graph dips or inconsistencies will be clear to see. The measurements shown are available and displayed per individual A/B number i.e. the caller and the callee .
