Om gebruik te kunnen maken van het externe telefoonboek van de UC-Suite oplossing (of andere databases waarin de telefoonnummers in full canonical format opgenomen zijn) moet je de  “Canonical dial Settings” op de CP400/600 (HFA) goed instellen

Zonder deze instellingen kunnen telefoonnummers die in “Canonical format” ingevoerd zijn in het externe telefoonboek (bijv. +31413724200) niet gekozen worden.

In Onderstaand screenshot is te zien welke instellingen minimaal benodigd zijn. Je kan deze info ook terugvinden in de Administrator Manuel van de OpenScape CP400/600 HFA toestellen.

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 national code, and Local enterprise number as prefixes. If, for instance, the user enters the extension "1234", the local country code is "49", the local national code is "89", and the local enterprise 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 required by the PBX.

Data required

• Local country code: E.164 Country code, e.g. "49" for Germany, "44" for United Kingdom.
  Maximum length: 5.
• National prefix digit: Prefix for national connections, e.g. "0" in Germany and United Kingdom. Maximum length: 5.
• Local national code: Local area code or city code, e.g. "89" for Munich, "20" for London.
  Maximum length: 6.
• Minimal local number length: Minimum number of digits in a local PSTN number, e.g.
  3335333 = 7 digits.
• Local enterprise node: Number of the company/PBX wherein the phone is residing. Maximum length: 10. (Optional)
• PSTN access code: Access code used for dialing out from a PBX to a PSTN. Maximum
  length: 10. (Optional)
• International access code: International prefix used to dial to another country, e.g. "00"
  in Germany and United Kingdom. Maximum length: 5.
• Operator codes: List of extension numbers for a connection to the operator. The numbers
  entered here are not converted to canonical format. Maximum length: 50. (Optional)
• Emergency numbers: List of emergency numbers to be used for the phone. If there are
  more than one numbers, they must be separated by commas. The numbers entered here
  are not converted to canonical format. Maximum length: 50. (Optional)
• Initial extension digits / Initial digits: List of initial digits of all possible extensions in the
  local enterprise network. When a call number could not be matched as a public network
  number, the phone checks if it is part of the local enterprise network. This is done by comparing the first digit of the call number to the value(s) given here. If it matches, the call number is recognized as a local enterprise number and processed accordingly. If, for instance, the extensions 3000-5999 are configured in the OpenScape Desk Phone
  IP, each number will start with 3, 4, or 5. Therefore, the digits to be entered are 3, 4, 5.
• Expected dial number: When checked, canonical conversion mechanism prefers PSTN
  access code + National prefix digit over the international access code.
