  2. Why Voxeo?

  3. Telephony Sucks

  4. There are a number of problems with Telephony today...

  5. Complex

  6. Arcane

  7. Proprietary

  8. This is not how it should be...

  9. Simple

  10. Ubiquitous

  11. Open

  12. What to do?

  13. Leverage The Web Model

  14. Disaggregate The Components

  15. Utilize Standards

  16. What Does It Look Like?

  17. Application XML+HTTP Platform SIP Network

  18. Application XML+HTTP Platform SIP Network

  19. Application Creation

  20. VoiceXML • W3C standard to define speech dialogs • Defines prompts and grammars that together create a phone application • Thousands of developers • 30+ Open source projects

  21. CCXML • CCXML is the W3C standard for call control using XML • Sister standard to VoiceXML • Integrates with VoiceXML for dialog control • Provides a framework for issuing call control commands and handling call control events

  22. Voxeo’sSolution

  23. Evolution

  24. Prophecy

  25. Example Application

  26. Sample Application Overview • Caller dials in to the application • Caller is bridged to the subscriber • Results of the call attempt are posted to Twitter via their REST API
