Country codes

Here you can assign the national prefixes to the country codes in canonical format.

Internal users can dial external call numbers directly in a standard canonical format. The communication server standardises the canonical phone number and, besides the additional characters and spaces, also removes the national prefix, if listed here.

Canonical call numbers

Canonical call numbers start with a “+” followed by the country code (e.g. 41), the national destination code (e.g. 32) and the local phone number (e.g. 655 55 55). The national prefix (e.g. 0) is often included so a user can also use the call number within the country itself. The characters “-”, “/”, “(“, “)” and “space” are also often used to make the number easier to read.

Examples of call numbers in canonical format:

+41326555555
+41 (0) 32 655 55 55
+41 (032) 655 55 55
+41-32 / 655 55 55

The main country codes with the relevant national prefixes are already entered as defaults. They are used by the communication server to filter out any national destination code that may be contained in the case of numbers in canonical format. Superfluous characters are removed at the same time so that the number +41326555555 results from all the examples listed above. This method is applied for both outgoing calls from phone book directories and for incoming international calls.

Finding a country code

To find a particular country code enter a country code (or parts of it) in the text field and click the Search button. All the country codes that contain the character string are listed. If the text field is left empty, all the stored country codes are listed.

Add country code and relevant national prefix

To add an entry to the country list, click the New button and enter the country code with the relevant national prefix. Click the Apply button to save the new entry.

notes:

The country code must begin with a “+” and then contain only digits.
The national prefix must contain digits only.
Each country code can only be listed once in the country list.

To delete one or more entries in the country list, click the Delete button, activate the entries to be deleted, and click the Delete button once again.
