Entrepreneurial Advantages with New Open-Source Technologies Jay Phillips, Ruby and VoIP Hacker, Adhearsion Date: Thursday, October 29 Time: 11:45 - 12:00 PM Location: Transformatorhuis As an industry how do we build scalable voice applications with open-source tools? How do we infuse talented web developers into the "uncool" telephony world? Why hasn't open-source completely dominated telephony like it has in other tech industries? These are some of the biggest questions facing the future of Emerging Communications and their answers are changing dramatically every year. Brewing at Voxeo Labs is an open-source approach to building arbitrarily sophisticated communications applications which promises to shake up the industry. In this session Jay Phillips, the new VP of R&D at Voxeo and creator of the open-source Adhearsion telephony framework, will discuss the exciting new ways developers and entrepreneurs will be able to easily build, productize, and scale telephony applications. As an open process, willing community members are also invited to help build this public asset and make their lasting marks in a profound way on the world.

18. “Voice is a Spice” - Thomas Howe
• Applications are about connecting people
• “Web 2.0” is about the social web
• Voice isn’t the application
• Innovating here is hard
• Innovators should build lots of little voice
experimental apps
• Master doing experiments quickly

23. Cloud Telephony
Once you build your
application, how do you scale
and operationalize it?
PROS CONS
• Usually cheapest solution • Can be a proprietary trap
• Easiest to setup • Some companies are fly-by-night
• Handles traffic spikes well • Some things may be impossible
• Support staff available • Asset ownership

Java’s back and it’s here to stay.
New open-source standards-based
Java frameworks rock
PROS CONS
• Very robust and powerful • JSR 309 and JSR 289 are very
boilerplate-heavy
• Standards-based
• Usually depend on a separate
• Many Java programmers media server
• Java tools are top-notch • Simple apps overly complicated
