Country codes

Tip: Always enter phone numbers in the international format. For example, enter a Dutch mobile number as +31612345678, where +31 is the country code.

Note: Set the correct country code if:

1. You do not use the international format for contacts’ phone numbers;
   
   
2. You use a PSTN connection that does not support the international format.

The alarm dialler provides a default country code list.

Change the country code

• Open Settings.
• Select Country codes in the navigation menu.
• Click Edit and choose how to set the country code:
  • Default per country: Click the double arrows and select the relevant country.
  • Custom: Tick the component and enter the required data as shown below.
• Click Save.

Country code explanation

The alarm dialler uses country codes to convert phone numbers for dialling out via PSTN, GSM, and SIP. The dialler converts numbers to:

• the international format for GSM and SIP;
• the local format for PSTN.

Local format (PSTN): area code – subscriber number

The area code consists of two parts:

• the long-distance access number (usually 0);
• the specific area code (the first 3 or 4 digits of a telephone number).

The subscriber number is the unique extension.

Example of the local format

Phone number Adésys: 0174 794022

International format (GSM and SIP): international access number – country code – area code – subscriber number

Good to know: The international format does not include the long-distance access number.

• The international access number is a series of digits used to start an international call.
• The country code identifies a specific country. Each country has a unique code.
