This setting is used to specify the type of the callee number. The service
provider will usually verify this. The default setting is "unknown". In some
very unusual circumstances, you may need set to "dynamic" or
"redundant".

When one type is selected, you might not be able to dial another class of
numbers. For example, if "national" is configured, you won't be able to
dial local or international numbers.
