LRT String Lookup

The Oracle® Enterprise Session Border Controller can search an LRT for either E.164 or string table keys. This selection is on a global basis. When the string-lookup parameter is disabled (default) in the local routing configuration, all lookups with be E.164 type, except when:

• If eloc-str-lkup is enabled in a matching local policy’s policy-attribute, E-CSCF procedures are applied and the resulting lookup type is 'string'.
• The Oracle® Enterprise Session Border Controller also performs string lookups exclusively when a compound lookup key is specified.

When the lookup type is 'E.164', the lookup is skipped if the lookup key is not a valid telephone number (i.e. it must contain only digits).
