What could be the reason, if phone numbers will not syncronize correctly?

To convert the phone number with the handset during synchronisation, the area number must be correctly entered in the Gigaset QuickSync as well in the handset.

The Area codes tab in the Settings of QuickSync allows you to set your current location area codes. 

 

The area codes consist of four entries in two groups:

  • International area code: These settings are used for international numbers. Please enter the international access code, e.g. 00 in the UK, in the left field. Please enter country area code, e.g. 44 for the UK, in the right field.
  • Local area code: These settings are used for long distance numbers. Please enter the long distance access code, e.g. 0 in the UK, in the left field. Please enter local regional area code, e.g. 20 for London, in the right field.
