■ Allowed Lists. Use to assign one or more Assigned Lists to the extension. 
Use the Allowed List tab to view the current extensions in that list. Use the 
‘Is User’ check box to add/remove the selected extension from the lists. 
Allowed List defines area codes and exchange prefixes that this extension 
user is allowed to dial when making an outside call.
■ Disallowed Lists. Use to assign one or more Unassigned Lists to the 
extension. Use the allowed list tab to view the current extensions in that list. 
Use the ‘Is User’ check box to add/remove the selected extension from the 
lists. Disallowed List defines area codes and exchange prefixes that this 
extension user is not allowed to dial when making an outside call.
■ Show Number List. If checked, the Allowed or Disallowed List is read from 
the MERLIN MAGIX system and displayed for the currently selected 
Allowed/Disallowed List.
■ The Standard SPM Mode Interface must be used to define Night 
Service Coverage.
■ Automatic Route Selection (ARS) allows outgoing calls to be 
dynamically routed over selected facilities after dialing an ARS 
access code (usually 9). This enables the MERLIN MAGIX 
Integrated System to select the least expensive route for each call 
based on the area code and prefix that the extension user dials.
