Telegram is testing Voice Chat feature for channels. This feature was announced by Telegram back in December 2020 but that was limited to groups only. Now, the company is gearing up to expand this feature to channels as well.
Telegram Voice Chat feature is a bit similar to Discord rooms. Users can participate in the voice chat and can simultaneously do other things on the app. Though Voice Chat is not Group calls, but it can achieve similar goals.
WABetaInfo has shared the screenshot, in which there is an option to start Voice Chat. The option can be found inside the channel’s details screen. Currently, it is available for a limited number of users. Soon, it should reach a wide number of users.
