The Dial Plan Parameters screen works with the Dial Plan Analysis Table to fully define the dial plan of your system. On the Dial Plan Parameters screen, you can set system-wide parameters for your dial plan. The Dial Plan Parameters screen also controls the appearance of 8-digit and 13-digit extensions on station displays. You can select a system-wide format to display all 8-digit extensions, and a format to display all 13-digit extensions.
