The Swiss messenger Threema will also offer voice calls in the future
The Swiss messenger Threema will also support encrypted voice calls in the future. Interested parties can try out a beta version and make suggestions for improvement.

The developers of Threema have announced a new feature for their instant messaging service. In the future, Threema will also support encrypted end-to-end voice calls, as the company announced on its Blog writes.
The connection between the call partners should not only be tap-proof, but also economical in terms of data transmission, as the blog goes on to say. A process that establishes contact directly between the devices guarantees encryption, the developers promise. A constant bit rate should also prevent any conclusions being drawn about the content.
The developers are calling for people to test the new voice calls. Interested parties can try out a beta version for Android and iOS and provide feedback on improvements. If you don't like the new feature, you should be able to deactivate it completely. (Netzwoche)
