What we have built over the course of this chapter is an adequate place to jump off into bigger and better things. It provides a baseline of features that almost every peer-to-peer communication application needs. From here, it is a matter of adding on common web application features to enhance the experience.

The login experience is one place to start improving the experience. There are a number of well-built services to enable user identification through common platforms like Facebook and Google. Integration with either of these APIs is easy and straightforward, and provides a great way to ensure that each user is unique. They also provide friend list capabilities so that the user has a list of people to call even if it is his/her first time using the application.

On top of this, the application will need to be foolproof to ensure the best possible experience. User input should be checked at each part of the way by both the client and server. Also, there are several places where the WebRTC connection can fail, such as not supporting the technology, not being able to traverse firewalls, and not having enough bandwidth to stream a video call. A wealth of work has gone into making common phone communication platforms stable to avoid dropped calls, and the same amount of work will have to go into making any WebRTC platform stable.
