The document discusses building application programming interfaces (APIs) for carriers to create platforms that improve existing communication products. It notes the success of the web was due to its ubiquitous and unified platform with simple common APIs. The author argues carriers should take a platform approach and reuse existing assets by turning phone calls into more valuable experiences through enabling apps during calls and integrating with real-time communication technologies like WebRTC. This would allow carriers to control call routing and media, conferencing, and collect user input rather than just being the pipe to apps.
