The system does not let you remove an extension list that the dial plan 
is using even if that extension list is empty. You must remove the 
extension list from the dial plan before you can delete the extension list.

To remove an extension list:

1 On the Extension Lists tab, select the extension list you want to remove.

2 Click Remove. A dialog box prompts you to confirm the removal.

3 Click Yes.

CAUTION: Do not remove any of the predefined lists (lists 1 through 8).

The NBX system associates a normal dial plan table and a Least Cost 
Routing table with each device. Devices include, for example, telephones, 
Analog Line Card ports, or Digital Line Card ports. A telephone that has 
no table assigned does not have permission to dial. A telephone without 
an assigned table is flagged in Reports. For details, see 

 on 

. For more information, see these topics:
