Fritzbox: Telephone always busy - that's why

This practical tip tells you what you can do if the Fritzbox phone is always busy.

Fritzbox phone always busy - possible causes

If the Fritzbox phone is always busy, several causes can be considered. Below we present some solutions:

First of all, make sure that your phone is correctly connected to the Fritzbox.
Also check whether the correct phone number is entered in the Fritzbox. You can check this in the user interface under "Telephony"> "Own numbers".
There you can also specify the location information under "Connection settings". Check whether these are set correctly.
You can also try to restart the Fritzbox. You can do this in the menu under "System"> "Backup"> "Restart".
You can use the status LED under "Telephony"> "Own numbers" to determine whether you have made the settings correctly. This is the case when the LED lights up green.
Your phone may also be defective. Exchange this for testing in order to be able to further narrow down the source of the error.
There may be an update for your Fritzbox. You can test this under "System"> "Firmware update".
Of course, you can also reset the Fritzbox to the factory settings. However, you will then have to set it up again.
Your provider may reject the dialed number or have temporarily blocked your connection. In this case you should contact your provider by phone.
