You can make one-on-one or group calls with anyone in your organization directly from a chat without having to host a team meeting. Up to 20 people can be on the same video call. These calls are private and won't appear in any team conversation. Entries for the calls will appear in your chat, though.
- Go to your chat list and select New message to start a new conversation.
- Type the name or names of participants next to To at the top of your new chat.
- Select Video call or Audio call to start a call.
You can also start a one-on-one call from someone's profile card. Open it by selecting their picture in a channel or from a search.
