FRITZ!Box 6490 Cable Service - Knowledge Base
Telephone numbers are missing after automatic configuration
After automatic configuration, one or more telephone numbers are missing under "Telephony > Telephone Numbers" in the user interface.
Important:If you received your FRITZ!Box from your cable provider as part of your service agreement, your telephone numbers are automatically configured in your FRITZ!Box as soon as you connect the FRITZ!Box to your cable connection. It is not possible to manually add telephone numbers from your cable provider later.
Simply proceed as described below. After each measure, check whether the issue persists.
1 Loading the FRITZ!Box factory settings
An error may have occurred during the automatic configuration procedure. Therefore, restore the FRITZ!Box to its factory settings so you can restart the automatic configuration of your telephone numbers:
- Load the FRITZ!Box's factory settings.
2 Contacting your provider
- If telephone numbers are still missing, contact your cable provider directly.
Note:First you must find out whether the missing telephone numbers are saved on your cable provider's Auto Configuration Server (ACS). However, only employees of the provider can check this.
