These settings are used for outgoing call routing on systems running in PBX system mode. They are applied to calls where the user goes off-hook and dials without selecting a line appearance button.
The ARS Selectors are used to create groups of lines. The same line can be in more than one group. These are then used as the destination for outgoing external calls.
The Dial Numbers table is used to match the number dialed by a user to a required ARS Select group number. When a match is found, an available line in that ARS Selector group is seized for the call.
