Canonical Dial Lookup - Siemens OpenStage 15 Administration Manual

3.7.2

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 (-> Section 3.7.1), internal numbers must be discerned from ex-
ternal 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.
To make sure that canonical dial lookup works properly, at least the following para-
>
meters of the phone must be provided:
• Local country code (-> Section 3.7.1)
• Local area code (-> Section 3.7.1)
• Local enterprise code (-> Section 3.7.1)
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.
Data required
• Local code 1 ... 5: Local enterprise code for the node/PBX the phone is connected to.
Example: "722" for Siemens Munich.
• International code 1 ... 5: Sequence of "+", local country code, local area code, and local
enterprise node corresponding to to one or more phone book entries.
Example: "+4989722" for Siemens Munich.
