Landline
Three variants to choose from: PhoneBlock dongle as a small USB stick in the router, Cloud answering machine via the Fritz!Box, or Blocklist phonebook as CardDAV sync. Which one suits you best depends on your router, provider and data protection requirements - the overview page compares all three side by side.
Android
Block spam calls directly on your Android cell phone with the PhoneBlock app. The app checks incoming calls in real time and automatically blocks known spam numbers. You can set yourself how many negative messages a number should be blocked for.
iPhone
Include the PhoneBlock blocklist in your iPhone contacts. iOS then automatically shows you when a caller is on the blocklist. The setup is done via CardDAV - your iPhone automatically keeps the list up to date.
Telephone system
Integrate PhoneBlock into your phone system or PBX. The blocklist can be downloaded in various formats or queried via API. Ideal for companies and professional telephone systems.
The community makes the difference
Strong together:
Anyone can join in! Report spam numbers directly in the app, on the website or by adding them to your personal blacklist. As soon as a number is reported, it will be added to the blacklist for all users. The more users participate, the better we can all protect ourselves from spam calls.
