6. Trend: Programming Languages
• What is the next killer language?
• Late 50’s - Fortran
• Late 60’s - ANSI COBOL
• Late 70’s - C
• Late 80’s - C++
• Late 90’s - Java

17. Adhearsion ’s Ruby

18. Trend Towards Open-source
• Virtually all programming languages
• Virtually all popular database systems
• Virtually all popular web servers
• What percent of new phone systems use
open-source?

19. Virtual Machines are Difficult
Python
Javascript Ruby
Scala Clojure
Groovy
• Open-source languages are converging on VMs

20. Telephony does not have a VM
• Must...
• Be fully open-source
• Support SIP
• Handle media (MRCP)
• Allow sophisticated bridging
• Cluster well
• Scale Well

21. Simplicity Trend
• Case in point...
• Drizzle fork of MySQL
• Dynamically-typed programming languages
• REST vs SOAP
• JSON or YAML over XML
• Ruby on Rails over “enterprise” Java

22. Trend: The Long Tail
Popularity
Applications

23. Converging Trends
• Trend toward polyglot programming
• Trend toward open-source
• Trend toward a unifying programming language VM
• Trend toward simplicity
• Trend toward “Long Tail” applications
• If you want a definition of “Voice 2.0”, this is it

24. Adhearsion is...
“Adhearsion is a new way to
write voice-enabled
applications. It's not just an
API or library — it's a fully-
featured framework, the first
of its kind, designed for
maximal code reuse and
intuitiveness. The name
quot;Adhearsionquot; is a
combination of quot;adhesionquot;
and quot;hearquot; because
Adhearsion shines best
when integrating
technologies with voice.”

25. The Adhearsion World
Application Ecosystem
(applications, plugins, GUIs, etc)
Telephony Domain

26. The Adhearsion World
Application Ecosystem
(applications, plugins, GUIs, etc)
Ruby
JRuby
Java
Telephony Engine
(Asterisk, FreeSWITCH, Tropo, SIP Servlets, MRCP, etc)

27. What Adhearsion is Not
• Not...
• Ruby
• Ruby on Rails
• An Asterisk module
• A library
• For handset client apps
• An application
• Like what Nortel, Avaya, AT&T or any vendor has

28. How Adhearsion Works

29. Adhearsion Dialplan.rb

30. Adhearsion Events.rb

31. Adhearsion Components

32. Adhearsion APIs
• Extendable through components ‘methods_for’
• REST/JSON
• Distributed Ruby (DRb)
• STOMP
• ...

33. Adhearsion Roadmap
Future - v0.9.x
Today - v0.8.x
(Planned)
v1.4.x
v1.6.x

34. Adhearsion Roadmap
API instead of VXML/CCXML
• Javascript, Groovy, PHP, Python, Ruby
• Working on ProtoTropo...

35. Adhearsion Roadmap
JSR 289 - SIP Servlets
•Sailfin (Glassfish)
•Micromethods (Voxeo)
•Mobicents
MRCP
•UniMRCP
•And others...
