In order to check the call history, you are required to log into your Vozy account with the administrator credentials, which are sent earlier through the email.
Go to the "Calls" or "Call History" option on the left menu.
Here, you can review and filter the call history by day, week, month, or a custom filter. Also it allows you to access to the cost, the caller, the receiver, the duration, and the record of each call. The records of the calls are only available if you previous set up to record calls. (This option is only for Pro/ Enterprise Plans.)
If there is any issue coming up during this process, please report it through the link below.
