TES allows for reports on the Extensions or the Usernames.
The Detailed Extension report:
Shows all the Calls that were made or received on the selected extensions. Pincode calls will show the extension number as the username.
The Detailed Extension Name report:
Show all the calls for the selected extension name. When a Call with a pincode is made, the extension name will bet set to the extension number. All other calls will show the extension name.
The Detailed Username report:
Show all the calls for a specific Pincode User and Extension username. If an extension name is the same as the Pincode username, the incoming calls for that extension will also be listed.
If the pincode was used on multiple extensions, all the extensions will be listed on this report.
