Call history shows the list of the calls made and received by the tenant. Due to the complex nature of call detail records, with calls splitting into multiple legs, multiple dialed legs and transfers (just to mention some), the list is quite complex and it can be tricky to check what has happened to a call.

Only some of the available fields are displayed by default. More fields can be shown pressing the “Column” button at the bottom and selecting the desired fields
From the Call History page is possible to access the Advanced Call Detail Records by pressing on the disposition link. The Advanced Call Detail Records offers a detailed view, packet capture and quality graphs on the call selected.

In the Call History field “Extra” you can find a loudspeaker allowing access to the recording for that leg. You can also find a yellow alert sign or red stop sign. In this case, the call had some problem and you can find additional details in the tooltip, moving the mouse over the sign.
If you are interested in getting an overview of the steps performed by the call, you can select any leg and press on the Call Steps
