The Number of Lines setting is used to automatically assign line appearance buttons on all extensions with programmable buttons. To make external calls the user should select an available line appearance button. Outbound call routing is determined by which line appearance button the user selects before dialing or by the user's automatic line selection settings.
No line appearances are automatically assigned to programmable buttons. The Outside Line setting is used to set the dialing prefix that indicates that the call is an external one for which an available line should be seized. The Alternate Route Selection settings are used to determine which lines are used for each outgoing call. Line appearance buttons can also still be configured for making and answering external calls.
