Q: Can I make calls via Telegram?

Yes! You can make end-to-end encrypted Voice Calls and Video Calls.

If you want more participants, try starting a Voice Chat in one of the groups you created. Voice Chats add a live layer of ephemeral talk to the group. They can be used as virtual office spaces for teams or informal lounges for any community. While Voice Chats are not group calls, they can achieve similar goals.
