Call line mapping
The Call line Mapping tab manages mappings from called line IDs to realms. Call line mappings are useful if you have a NAS authenticating for multiple dialup numbers that map to different realms.
A mapping consists of the phone number that is dialled and the realm that it maps to. If no match is found in the call line mapping table then the NAS's default is used.
The Call line mapping tab displays a summary table of mappings.
