As posted on their official blog, Telegram is set to introduce voice call functionality into its app for the first time, and it comes with a cherry on top: Telegram Calls will be end-to-end encrypted.
For those who are not well-versed with the term, end-to-end encryption refers to the type of security that protects a conversation, whether text, audio, or video-based, from an attack to reveal its contents. It is called “end-to-end” because it effectively slams the door shut for any attempts to gain access from both the sender and receiver’s ends, or in this case, dialer and receiver’s end.
Telegram came to worldwide attention after the acquisition of WhatsApp by Facebook in 2014. Its point of differentiation, among a whole host of other messaging apps each with their own unique proposition, was end-to-end encryption in text messaging. At the time of its launch, Telegram was the only the second chat app, beside Apple’s iMessage that was the first of its kind, to offer such a sophisticated security solution for its users. It is how the service marketed itself, and it was soon branded as arguably the most secure online messaging app in the market.
It is how Telegram now boasts more than 100 million monthly active users (MAUs) with around 350,000 joining up every day. As for Telegram Calls, users in Europe will be the first ones to get the voice call feature with the update, with users from other regions getting it soon after.
Secure, Crystal Clear, and AI-Powered is the mantra behind E2E-powered voice calls on Telegram. Secure because of end-to-end encryption, crystal clear because of the service’s analysis and optimization of ping, network speed, etc, and AI-powered because of its aim to improve voice quality during calls continuously using artificial intelligence.
