Advanced WebRTC Button Customization

For those looking for more advanced customization options of the WebRTC button, here is the full source code for our WebRTC button, InstaCall, on GitHub. Feel free to fork the repository, as well as submit pull requests with any suggested improvements.

HTML Data Parameters

Once forked from the GitHub repository, adding parameters to InstaCall will break compatibility with the InstaCall Generate Admin API action. Extra parameters should be defined on the InstaCall button as attributes prefixed with data- to allow JavaScript easy access to the option. A full listing of existing options appears below. Note that some of these options are experimental and not configurable through the InstaCall Generate action alone.
