Cross-devices Blacklists for Registered tellows Members

Dear tellows fellows,

more and more frequently consumers are victims of telephone spam or frauds, or are simply provoked by frequent unwanted calls. They use various tricks to pull our money out of our pockets. Here in our community, many phone owners report and rate the numbers that called them, sharing their experiences with other users to protect you and themselves. This works in an easy and uncomplicated way.

The heart of us is the tellows score. It is calculated from all previously stored ratings for a specific phone number. Users of the community can report and rate phone numbers on a scale of 1-9, where 9 means that a very dangerous or very annoying phone call is on the line and 1 is a rather harmless one. So you can rate and categorize each phone number on a scale from 1 (trustworthy) to 9 (dubious). From 7 on, the corresponding phone number is placed on a blacklist of the community and is thus blocked for everyone using the tellows products by itself and provides an appropriate protection. Depending on the rating, you can then assess the seriousness of a called number. In this way you can inform yourself online about the experience other users have already made with the respective number. And if there is a cost trap or telephone fraud behind it, you can know it because of the negatively rated number before they call you back again. Additionally, you can create your personal blacklist and add unwanted numbers that are not yet rated or don’t appear in the blacklist. If you rate a number negatively, it will be added to your personal blacklist and will be blocked the next time you receive a call. Even if the overall rating assigned by other tellows users of the phone number is different, it will still be blocked.

In order to be able to benefit from the collected assessments and experiences at an early stage, for example even before a call is answered, the successful tellows app for devices with Android or iOS was developed. This already indicates during the ringing, how trustworthy the calling number is by using the reports of the community. Thus, when the call is received, the tellows score is displayed.

French University Project with tellows API

Dear tellows fellows,

tellows is versatile and the tellows data can be used for different systems. We developed an API that suits all kinds of projects and allows you to access the database and use the number details as preferred.

Today, we want to introduce a student project from the UPMC University in Paris, which was realized with the help of the tellows API.
For the students, the task was to build an Android App with an API. The idea was to develop a caller ID that identifies French numbers and shows whether a number is dangerous or trustworthy. With the help of our API, they managed to build the App in just a few weeks. As soon as a call comes in, it shows the respective tellows score that indicates if the number is dangerous or not. Opening the app, it will show a list of all recently received calls. Furthermore, it displays the number, score and country.

The final result was presented within the class and turned out successful. We are happy that we could be part of it and help to realize the project. However, a publication of the application is not possible.

New iPhone App Cooperation – Caller ID & Blocker with #SCB

Dear tellows users,

we are happy to announce a partnership with the app developer Sergey Smirnov. He developed the iPhone app #SCB • Caller ID & Blocker to identify and block unwanted calls. Additionally you can put numbers on a personal black- or whitelist. The app also allows you to filter and block incoming SMS messages.

The #SCB app uses the tellows database to identify unknown numbers. Therefore spam numbers like robocalls, telemarketers and advertising can be identified before the user picks up the phone and saves you lots of time. If you have been bothered by a number that has not been reported, you can add it to your blacklist and report it to warn others about this number as well.
