Canonical Dial Lookup
The parameters given here are important for establishing outgoing calls and for recognizing in-
coming calls.
In the local phonebook numbers are stored in canonical format. In order to generate an appropri-
ate dial string according to the settings in
Internal numbers
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 international
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.
Up to 5 patterns can be defined. The
Local code 1 ... 5
parameters define up to 5 different local
enterprise nodes, whilst
International code 1... 5
define up to 5 international codes, that is, fully
qualified E.164 call numbers for use in a PSTN.
