You are a few clicks away from calling anyone. Use the keypad to start a call and press the green icon to confirm.
You can also call from your contacts. Open Contacts in the bottom panel and tap a person to call.

If you gave Channels permission to make calls, incoming calls will appear in your phone's native dialer.
Calls will look like regular calls but will show which Channels number they're from and the contact information. To receive them, stay logged in to the mobile app and keep it running in the background.
