Telekom released a new update on March 15. FritzBox owners have been informed for a few days that they should definitely update their routers to FritzOS version 7.29 or later, otherwise they will no longer be able to make calls like Mobiflip. reported.
This affects users running FritzOS 7.25 to 7.28. Internet access will continue to work for affected users.
Telekom warns: FritzBox owners need to update urgently
The reason: AVM used the TLS interface for encrypted communication with the FritzOS 7.25 update. However, the RTP media stream is transmitted unencrypted. This violates current security standards.
If you are using a version older than FritzOS 7.25 on your router, you can still make calls as usual even after the Telekom update. However, it is advisable to always keep your devices up to date with updates, otherwise it is easier to fall victim to cyber attacks and the like and the stability of the device suffers.
