Twilio developer evangelist here.

Twilio Video WebRTC Go can connect two users in a video room. Twilio Video does not provide any specific tools for making an outbound video call in JavaScript though, so you will need to build a notification system yourself to handle that. I do not have an example for this.

If you have a specific issue when implementing this, I recommend you open a new question and share some code so the community can see what you've tried and help out.
