Enhanced DXS Tracking is helpful if you have more than 100 telephones, but use a console that does not have Hundreds Select buttons administered. Enhanced DXS Tracking is also helpful if you have more telephones than Hundreds Select buttons, and thus have hundreds groups that are administered with Hundreds Select buttons.

To use Enhanced DXS, assign a Group Select button on the Attendant Console screen. The attendant uses this button to track and extend calls to telephones that do not have associated Hundreds Select buttons. You cannot use Enhanced DXS Tracking if your extensions have fewer than 3 digits.
