"Coming soon will be voice and video chat from your handle to anyone on this platform," the twitter boss said in a tweet. "So you can talk to people anywhere in the world without giving them your phone number".
He later on added that the feature that will be brought won't be used on Meta as it is not trustable.
This feature will compete with a number of services with the same functions, such as Messenger, Signal, Telegram and WhatsApp.
He said that Twitter will start encrypting direct messages on the platform, to scramble content in order to protect the user’s privacy.
Since buying the platform last year, Musk has made a lot of changes that have angered some users around the world.
Musk recently also talked about introducing an all-purpose 'X' application that will include messages, payments and more.
