@telegram: Secure Group Calls. Telegram's secure calls can be easily expanded to hold up to 200 users – all protected by end-to-end encryption. Telegram calls can be used for anything from spontaneous chats to job interviews: • Add other users to an active call by tapping in the top corner. • Start a call with several users via the 'Calls' tab or Settings > Recent Calls – tap 'New Call' and select multiple people. • Send a link to the call to create scheduled meetings or invite multiple groups. #TelegramTips
