That means numbers in brackets in the call list


You have recently received a few calls in which your telephone shows two numbers on the display: one normal and a second in brackets. What do these numbers mean?

Some of these are annoying advertising calls, but some are also contacting reputable companies. If you look in the Fritzbox’s call directory, you will also see a corresponding entry with a phone number followed by another number in brackets.

There are two phone numbers that are transmitted when you call: One is the so-called “User Provided Number”, which the Fritzbox displays at the front, and the other is the so-called “Network Provided Number” in brackets. The latter is the real telephone number via which the call is made and which is assigned by a telephone provider. The caller, on the other hand, can determine the “User Provided Number” himself. Large companies use this procedure, for example, so that they can be reached via an easy-to-remember number or can display it to the person called – for example an 0800 number. In this way, the call can be quickly assigned to the company, even if it actually comes from a local branch with a different number. However, dubious callers can use it to hide their actual phone number or their location, since it depends on the phone of the person called whether both numbers or only the self-created “User Provided Number” is displayed.

In the Fritzbox's call list, a telephone number is in brackets if a caller sends a self-created one instead of the actual telephone number.

In the Fritzbox’s call list, a telephone number is in brackets if a caller sends a self-created one instead of the actual telephone number.

With the help of the Fritzbox, you can block these calls using a number you set yourself. This is particularly easy with an AVM router on which at least Fritz OS 7 is installed: Log in to the Fritzbox menu and go to “Telephony -> Calls”. At the end of the line of the call, click on the phone book symbol with the bracket: In the next window select the option “Call barring” and confirm with “Next”.
