Formatting rules

You can change and individually format phone numbers with special rules. This can be done using Search/Replace or Regular expressions. Besides the formatting rules, phone numbers can also be changed internally/externally via those rules. Depending on whether the phone number has been registered by the telephone system or sent for dialing to the telephone system, the sequence of processing the rules will be changed. Additional information about the sequence in which the rules will be applied are described in the sections Phone Number Formatting and Dialing Rules.

The rules permit detection of phone numbers based on Regular Expressions or direct comparison. Each entry can be configured individually. If the Replace With column has been entered, the phone number will be replaced automatically. The configured rules will be processed from top to bottom until the first match has been found.

Formatting Phone Numbers that have been registered by the Telephone System
Note the order of the Phone number formatting.

• Incoming
  Phone numbers for incoming calls which are reported to the PC by the phone system are formatted with these rules.
  These phone numbers come directly from the phone system as dialable digits. They consist exclusively of digits and also * and #.
  The phone number may include an external dialing code and, optionally, be an international, national, local or internal phone number.
  
• Outgoing
  Numbers for outgoing calls which are reported to the PC by the phone system are formatted with these rules.
  These phone numbers come directly from the phone system as dialable digits. They consist exclusively of digits and also * and #.
  The phone number may include an external dialing code and, optionally, be an international, national, local or internal phone number.
  

Formatting Phone Numbers before They are transferred to the Telephone System for Dialing:
The sequence in which phone numbers will be adjusted for Dialing has to be observed.

• PC dialing
  Phone numbers for outgoing calls which are to be dialed.
  These rules will be applied after the phone number has been transferred in International Format.
  At networked locations, this list will show generated expressions, given a corresponding configuration in the Advanced Location Settings, in order to convert long phone numbers from other locations into DDI phone numbers.
  
• PC dialing final
  Phone numbers for outgoing calls which are to be dialed.
  These rules are applied directly before the phone number is sent to the phone system.
  The phone has already been formatted for dialing (with the External Dialing Code).
  

	Specific Examples for Formatting Phone Numbers: Removing cross-network identifiers for registered phone numbers. Setting the cross-network identifier when a call should not go through the external telecommunications provider but rather through the internal location network. Replacing phone numbers when they should not be visible for other users at the application layer level.
	If a comprehensive set of rules should be established, the list can be maintained outside the administrator's utility. Existing rules can be exported as XML or CSV files, adjusted correspondingly and then re-imported.
