3.6.2 Canonical Dial Lookup
The parameters given here are important for establishing outgoing calls and for recognizing in-
coming calls.
In the local phonebook, and, mostly, in LDAP directories, numbers are stored in canonical for-
mat. In order to generate an appropriate dial string according to the settings in Internal num-
bers and External numbers, internal numbers must be discerned from external numbers. The
canonical lookup table provides patterns which allow for operation.
Furthermore, these patterns enable the phone to identify callers from different local or interna-
tional telephone networks by looking up the caller’s number in the phone book. As incoming
numbers are not always in canonical format, their composition must be analyzed first. For this
purpose, an incoming number is matched against one or more patterns consisting of country
codes, national codes, and enterprise nodes. Then, the result of this operation is matched
against the entries in the local phone book.
