Final Stage of
Technological Evolution

13. Where are we going?

14. Where are we going?
• Cost of minutes are approaching zero
• Software development is getting easier
• Backend telephony moving to the handset
• Less investment capital to go around
• Business models based on cloud computing

15. Innovation is all about
the applications

19. “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. Fast App Development
Non-Voice Technology Voice Technology
• Ruby on Rails
• Cloud telephony
• jQuery / YUI (e.g. Tropo.com)
• Dynamic languages • Java: JSR 309 and JSR 289
• MySQL, PostgreSQL, Sqlite • FreeSWITCH
• Cassandra, CouchDB, Redis • Asterisk
• ORMs for relational DBs • Yate
• Linux • Adhearsion
• Reuse open-source code! • OpenSIPs / Kamailio
• UniMRCP

24. 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

25. Voxeo.com Tropo.com
Very Affordable
Enterprise Telephony
Scripting Language
Application Hosting
Telephony Hosting

26. Java Powered Telephony
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
SIPMethod, Mobicents, SailFin

27. Voxeo is open-sourcing
SIPMethod!

28. Asterisk
The grandpa of
open-source telephony.
10 years old!
PROS CONS
• Most popular open-source
• Very expensive to scale
telephony solution
• APIs are super yucky
• Large community
• Hard to reuse stuff
• Does what it was
designed for pretty well • Very limited features
• Supported by Digium • Lots of legacy code

29. FreeSWITCH
Basically “Asterisk 2.0”
PROS CONS
• Very scalable
• Modular architecture • Some features never been used
• Lots of features • Integration options could be
improved
• Good single-process
scalability • Clustering will still be expensive
• Supported by Barracuda

30. Adhearsion
Very modern open-source
telephony development framework
PROS CONS
• Very fast development
• Ruby (and Java) only
• Intuitive environment
• Limited by Asterisk
• Virtually no boilerplate
• FreeSWITCH and Tropo
• Super easy integration bindings are immature

31. OpenSIPS / Kamailio
These sibling projects let you build
very scalable SIP-only “applications.”
PROS CONS
• Very fast
• Community now split
• Reliable
• Few exciting uses of pure-SIP
• Great for building clusters applications

32. UniMRCP
General-purpose, modular,
standards-based media server
PROS CONS
• MRCP is very powerful
• MRCP 2.0 very new
• Very modular
• Few good open-source MRCP
• Removes lock-in with clients
proprietary telephony
technology vendors • MRCP is very complex
