15.2.1 Number formats
To be able to effectively use Lotus/IBM/HCL Notes together with SwyxIt! Classic, the external numbers in Lotus/IBM/HCL Notes contacts must be adjusted to the so-called “canonical telephone number format”. A canonical number always begins with a plus sign. This is followed by the country code (‘49’ for Germany), the local area code without the preceding zero in parentheses, and then the number.
Example of a number in Munich, Germany:
+49 (89) 12345678
You can add spaces to improve the clarity of the number, however, it is not necessary. Extension numbers, in the case of private branch exchanges, can also be separated from the subscriber number by a hyphen.
Example:
+49 (89) 12345-67
Pay attention to the country-specific particularities, as in Italy, for example: The preceding zero must be included here in the local area code.
