Exporting PBX Data

We need to have the ability to export all of the tables that are found in the PBX to a CSV file. The button exists in the "Users" tab, but is not found anywhere else. Someone within my company just asked me if I could provide a list of phone numbers and where they are routed to and I am simply unable to accomplish that task.  I desperately need this function at least in the "Phone Numbers" tab of the PBX.
