We have already made a comparison between Telegram and Whatsapp and although Facebook has brought many new features to Whatsapp in the last year, Telegram, clearly less popular, still wins for the guaranteed degree of security and in the bots, which are, for me, the real added value of Telegram, but it lacked the voice or video call function, at least until today. With the latest update, Telegram joins the apps to make free calls like Viber, Whatsapp and Facebook Messenger, doing it better than the others.
Unlike many other applications, voice calls between Telegram users are secure and encrypted in a guaranteed way and with superior quality thanks to artificial intelligence.
End-to-end encryption of calls in Telegram is the same as secret chat, the method that prevents any possible attempt to sniff or intercept communications even by government authorities or hacker organizations or Telegram employees.
The voice call feature in Telegram supports default end-to-end encryption, allowing users to protect their chats in a way that nobody can intercept calls.
In Telegram's call there is a very easy way to know if the person who called is really the person who answered or if the call is spied on (via Man in the middle attack)
The mechanism, also proof of the CIA spy, is made up of 4 emoji symbols that appear on the screen of the two phones during the call.
If these symbols are the same, then the call is secure, otherwise there is something wrong and there may be an intrusion.
To make sure the call is 100% secure, we need to compare the four emojis that appear on our phone with those that appear on the other person's cell phone.
Furthermore, Telegram calls have a very high and superior audio quality even compared to other apps such as Skype and Whatsapp because it uses better codecs and artificial intelligence.
Thus, each time a voice call is made, the application's neural network AI optimizes dozens of parameters based on the technical information of the device and the network speed to adjust the quality of the call and optimize it.
These parameters can also be automatically adjusted during a conversation, using less data in case of bad reception.
Unlike WhatsApp and Facebook, Telegram also allows you to control who can and who cannot call us precisely, blocking, in Settings> Privacy, specific people from the ability to call us or even to not let us call anyone.
For those who have not yet done so, I really recommend downloading and installing Telegram on Android and iPhone and using the free calls function with friends and family.
On this occasion, I also remind those who use Telegram to add the Navigaweb bot to receive articles on the chat.
