== | ==Detail report for an individual call== | ||
Next to each and every specific call, you will find a couple of buttons to make your life so much easier. Please note that the column toggle “PCAP” must be enabled. Right now we will go into the “Details” button as highlighted below. | Next to each and every specific call, you will find a couple of buttons to make your life so much easier.

When the call details page is opened, it is important to first click on one of the “Zoom” to call buttons. When doing so, the data shown in the Allegro Network Multimeter will be focused (or zoomed in) on the exact time and duration in which the call started and ended. You will now see the data and statistics revolving the call nicely centered in their respective graphs. | When the call details page is opened, it is important to first click on one of the “Zoom” to call buttons.

Condensed into one view, you’ll find your facts and figures about the codecs and the network on the left hand side of the screen, trending graphs of key quality metrics in the middle and capture buttons on the right of the screen. | Condensed into one view, you’ll find your facts and figures about the codecs and the network on the left hand side of the screen, trending graphs of key quality metrics in the middle and capture buttons on the right of the screen. | ||
=== 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. | |||
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 . | |||
