Voice and video calls

You can make voice and video calls from 1:1 to up to 200 people at the same time.

You can join a call via the mobile or PC apps. You must allow access to the microphone and camera before starting.

Calls between v2.9 or prior versions and v3.0 or later versions are not supported. For a calling experience without an issue, please update your app to v3.0.
