A new update for the Telegram chat client adds voice calling support for the Windows 10 mobile devices. This feature is already being available in Android and iOS platforms. Now it is available for Windows mobile devices too.
The Voice Call interface is familiar and easy to use, but as always, you get loads of innovation under the hood with Telegram. Telegram Calls are built upon the time-tested end-to-end encryption of Telegram’s Secret Chats. The key verification UI they came up with in 2013 to protect against man-in-the-middle attacks served well for Telegram (and for other apps that adopted it), but for Calls, they needed something easier. That‘s why they’ve improved the key exchange mechanism. To make sure your call is 100% secure, you and your recipient just need to compare four emoji over the phone. No lengthy codes or complicated pictures!
