Canonical Dialing Configuration

Call numbers taken from a directory application, LDAP for instance, are mostly expressed in
canonical format. Moreover, call numbers entered into the local phone book are automatically
converted and stored in canonical format, thereby adding "+", Local country code, Local na-
tional code, and Local enterprise number as prefixes. If, for instance, the user enters the ex-
tension "1234", the local country code is "49", the local national code is "89", and the local en-
terprise number is "722", the resulting number in canonical format is "+49897221234".
For generating an appropiate dial string, a conversion from canonical format may be required.
The following parameters determine the local settings of the phone, like Local country code
or Local national code, and define rules for converting from canonical format to the format re-
quired by the PBX.
To enable the number conversion, all parameters not marked as optional must be
provided, and the canonical lookup settings must be configured (see section 3.6.2,
"Canonical Dial Lookup").
