Dialing rules are used to define telephone numbers and number masks for calls (regional, national and international). Each dialing rule determines the types of calls that can be made. Supported by two examples, this article outlines how to correctly configure the dial rule entry when using TelephoneIntegration (TI) Client. 

The following 4 numbers are crucial when creating a new dialing rule in TI Client. So it is very important that you know your
CountryCode​
ExitCode
AreaCode
TrunkCode

Example 1
Before we create a dialing rule for Graz, Austria we need to know, that the following rules apply for that country/town:
CountryCode​ = 43
ExitCode = 00
TrunkCode = 0
AreaCode = 316
OutsideAccess = 0
Please note: The OutsideAccess number depends on the local companies' phone system, which means that it can vary. 

Example A:
We want to contact someone in Graz. (0316/123456789)
So all we need to dial is the OutsideAccess + the telephone number
The number we would have to dial is 0 123456789.

Example B:  
We want to contact someone in Salzburg, which is an Austrian city (famous for Mozart). (0662/123456789)
So all we need to dial is the OutsideAccess + the TrunkCode + Salzburg's Area Code + the telephone number
The number we would have to dial is 0 0 662 123456789.

Example C: 
We want to contact someone in Atlanta, Georgia. (0404/123456789)
So all we need to dial is the OutsideAccess + Austria's ExitCode + the USA CountryCode + Atlanta's Area Code + the telephone number
The number we would have to dial is 0 00 1 404 123456789.

Example 2:
Before we create a dialing rule for Atlanta, Georgia (USA) we need to know, that the following rules apply for that country/town:
CountryCode​ = 1
ExitCode = 011
TrunkCode = 1
AreaCode = 404
OutsideAccess = 9
Please note: The OutsideAccess number depends on the local companies' phone system, which means that it can vary. 

Example A: 
We want to contact someone in Atlanta. (0404/123456789)
So all we need to dial is the OutsideAccess + the telephone number
The number we would have to dial is 9 123456789.

Example B:  
We want to contact someone in New York (famous for the Statue of Liberty). (0917/123456789)
So all we need to dial is the OutsideAccess + the TrunkCode + New York's Area Code + the telephone number
The number we would have to dial is 9 1 917 123456789.

Example C: 
We want to contact someone in Graz, Austira. (0316/123456789)
So all we need to dial is the OutsideAccess + the US ExitCode + Austria's CountryCode + the Area Code of Graz + the telephone number
The number we would have to dial is 9 011 43 316 123456789.

How to activate dialing rules in TI Client?

This example outlines how to create a settingskey for a number that is from the United States. If you haven't created a settingskey yet, please have a look at this blog article. To enable this logic, you must create the below settingskey:

HKEY_CURRENT_USER\Software\PTM EDV-Systeme\TelephoneIntegrationclient2011
String value: BasicPreprocessing
Data value: true

The US has the country code 1, the exit code 011 and the trunk code 1. So, we must add 2 new registry string values:

String Value: TrunkCode
Data Value: 1

String Value: ExitCode
Data Value: 011

As soon as you have finished, do not forget to save your settings and restart the TelephoneIntegration Client.
