Reference7:Administration/Relay/Interfaces/Maps
Number mappings performed on the interface. There are mappings for calls coming in from the interface (CGPN-In, CDPN-In) and mappings for calls going out on the interface (CGPN-Out, CDPN-Out). The Called Party Number (CDPN) and the Calling Party Number (CGPN) can be mapped.
For calls coming in on the interface the number can be mapped from a representation using different Type of Number codings (National, International, Subscriber, ...) to a representation using the type Unknown and prefixes.
A '.' at the left side of a mapping matches any digit.
For calls going out on the interface the number can be mapped from a representation using the type Unknown and prefixes to a representation using different Type of Number codings (National, International, Subscriber, ...).
In the last column the numbering plan can be configuerd. The numbering plan may be forwarded unchanged or may be set to Unknown, ISDN or Private. The Private numbering plan is widely used to mark internal calls.
