Dialing rules

The dialing rules influence the formatting of phone numbers when dialing from a PC.

The phone number is formatted in this order:

  1. Formatting
    All characters apart from + * # 0 1 2 3 4 5 6 7 8 9 a b c d e f g h i j k l m n o p q r s t u v w x y z are removed. All letters are turned into capitals.
  2. Vanity phone number recognition
    If the number contains one of the configured vanity numbers and if the letters following it are valid according to the ITU E.161 rules the number is first converted into dialable digits.
  3. Further formatting
    All digits apart from + * # 0 1 2 3 4 5 6 7 8 9 are removed.
  4. Recognition of specific external numbers
    An external phone number is detected using the rules for external phone numbers. If such a number is detected, it will be dialed without additional formatting.
  5. Recognition of internal numbers
    A decision is made by means of the rules for internal numbers as to whether it is an internal number in the system. If an internal number is recognized it is dialed without further formatting.
  6. Phone number standardisation
    The phone number will be changed in the Super canonic phone number format.
  7. Using least cost routing
    If they have been configured the least cost routing rules are used.
  8. Transformation of external phone numbers into internal numbers
    If you have configured a system phone number (system line) a check is made as to whether the phone number is an internal number. If an internal number is recognised the number is shortened.
  9. Using the PC dialing rules
    The phone number runs through the special rules for PC dialing.
  10. Transformation into a dialable number
    The phone number is reformatted into a dialable number according to the rules of the configured country. The country dialing rules are stored in a Configuration file (countries.xml).
  11. Using external dialing codes
    The appropriate external dialing code(s) is/are added.
  12. Using the PC final dialing rules
    These rules are applied directly before the phone number is sent to the phone system.
  13. Dialing the number
    The number is sent to the phone system.
