FritzBox Integration


Your advantages

With tellows call protection you can immediately identify dubious phone numbers or unwanted advertising calls. By importing the phone numbers, the FritzBox recognizes unwanted callers who are known to the tellows community as soon as they ring. You can choose whether you want to show incoming calls on the display, silence them or block them! The tellows score helps you assess the seriousness. The higher the score, the more dangerous the number. Reminder service: We will remind you by email so that your license does not expire unnoticed.

Extend license for 1 year free of charge

By registering on tellows.de you can link your license to your tellows user account. This allows you to maintain personal blocking lists and use them across devices. Your reviews on tellows.de will then also be taken into account in the FritzBox telephone books. Certain license codes from tellows partners can unlock an additional year of call protection as a bonus. To do this, the license code must be linked to the user account in the member area of tellows.de under “My phone blacklist”.

Newer FRITZ!Boxes and current FRITZ!OS versions from 7.24 have improved support for online phone books and in most cases can also exceed the official phone book limit of 1,000 entries without any problems. We do not recommend the change for older FRITZ!Box versions. If you would like to have more phone numbers in your phone book to expand call protection, you can adjust the limit of phone book entries with the following URLs when creating the phone books: https://dav.tellows.de/score/7/limit_1200/ https:// dav.tellows.de/score/8-9/limit_1200/ The total number of entries per phone book with these URLs is 1,200. The limit per telephone book is 1,900 entries. You can therefore further increase the limit specified in the links if this does not put too much strain on your FRITZ!Box. To create a phone book with more entries, you should remove the existing phone books and create new ones (editing phone books is only possible from FRITZ!OS 7.24 onwards, otherwise changes will be overwritten with the original value). The username and password remain the same.

If you then purchase the product againYour old license key can be reactivated with the same shop account that was used for the first purchase. After completing the purchase, you must open the PDF document with the documentation in the download area of your shop account as you did for the first purchase. At this moment your license will be reactivated. In the document you will find your license and a note that the existing license has been renewed. You don't have to do anything else afterwards. The FritzBox will automatically obtain the current lists again with the next update with the reactivated license, so that no further configurations are necessary. If you purchased your license through a partner shop (e.g. Amazon) and created an account on tellows.de and linked it to your license in the member areayou can also extend your license.

If an error message occurs after integration (error 22), the data was entered incorrectly and access to the server was not possible. Make sure that there are no spaces before or after the server address. Use https and not http . Make sure all characters in the URL are lowercase. In the best case scenario, copy the URL from the instructions. If a character is missing or incorrect, connection to the server is not possible. Correct your details and then try connecting again.

If an error message occurs after integration (Error 26), remove the phone book completely and recreate it. It may happen that an error occurs on the first attempt. Make sure to use a slash at the end of the server address. If a character is missing, a connection to the server is not possible. Phonebooks once created and later changed may not be saved correctly with the new changes. If there was an error when you first created the phone book, your corrections will probably not be taken into account. For this reason, the telephone book should be recreated. If you create the phone book again, we recommend restarting the Fritzbox beforehand and deleting the old incorrect phone books. If you create a previously created phone book again, give the phone book a different name. It may happen that the Fritzbox loads the old data import from memory when the phone book is created again with the same name.

It is possible that you will be called from numbers that tellows does not yet recognize. Unfortunately, we cannot cover 100% of all unwanted calls because phone numbers change very frequently and we are only informed about them when they are reported by other users. However, it is also possible that some of these numbers have already been reported on tellows but are not in the phone book due to the phone book limit. Due to the limitation of the FRITZ!Box phone book size, we cannot include all numbers that contain a negative tellows score in the lists. In order for numbers to end up on the list, they must have a certain search volume and a certain number of reviews (at least 3) in the last few weeks. It is possible that the number will also end up on the lists soon, if users continue to report the number as active. We use this procedure so that numbers that are no longer active or are misrated do not end up on the list. You have the option to change the list size manually and increase the standard size to include numbers that meet the criteria but are too far behind are in the blocked list, but still have to be included in the FritzBox. To do this, follow the followingInstructions
.

Older FRITZ!Boxes and older FRITZ!Fons may take more time to update or may be more heavily utilized. We recommend reducing the number of entries in the telephone book so that the utilization is lower. The default value for the number of entries per phone book is 800. There are usually no problems with 700 entries. To create a phone book with fewer entries, you should remove the existing tellows phone books and create new ones with the following URLs: https://dav.tellows.de/score/7/limit_700/ https://dav.tellows.de/score/ 8-9/limit_700/ The username and password remain the same. You can try to further increase or decrease the limit parameter if you want to use more entries in your phone book and have no performance problems with the FRITZ!

You can remove, edit or manually add entries in the two tellows phone books at any time. You can find out how to proceed in the section on expanding the blocked list and reporting new phone numbers .

The standard value for the number of entries per phone book is 800. Newer FRITZ!Boxes and current FRITZ!OS versions from 7.24 have improved support for online phone books and in most cases can also exceed the official phone book limit of 1,000 entries without any problems. We do not recommend the change for older FRITZ!Box versions. If you would like to have more phone numbers in your phone book to expand call protection, you can adjust the limit of phone book entries with the following URLs when creating the phone books: https://dav.tellows.de/score/7/limit_1200/ https:// dav.tellows.de/score/8-9/limit_1200/ The total number of entries per phone book with these URLs is 1,200. The limit per telephone book is 1,900 entries. You can therefore further increase the limit specified in the links if this does not put too much strain on your FRITZ!Box. To create a phone book with more entries, you should remove the existing phone books and create new ones (editing phone books is only possible from FRITZ!OS 7.24 onwards, otherwise changes will be overwritten with the original value). The username and password remain the same.

The active phone book of a FRITZ!Fon is used by default for storing contacts, but has nothing to do with recognizing calls. All telephone books created in the FRITZ!Box are taken into account for identification in the FRITZ!Fon.

Each tellows phone book contains an entry at the top indicating the validity of the license and the last update date. The Fritz!Box updates once a day.

Unfortunately no, because call centers constantly change their numbers so that blocks and the like can be avoided. However, regularly updating the lists can lead to a significant improvement in the situation.

So far, Fritz!Boxes with Fritz!OS 7.20 and higher as well as the laboratory version of 7.19 support CardDAV server integration. Check whether an update is possible for your Fritz!Box. If the function is not supported at all, you can activate do not disturb manually by creating two phone books and importing the blocking lists. These must be updated manually on a regular basis. You can find the procedure in the instructions for manual import .
