WHY ARE YOU HERE?

To Watch Boring Presentations?

To Browse The Web?

Or To Change The World?

Get Passionate OR Get Out!

So lets talk about...

Innovation

Telephony

Locked Out

This is not how it
has to be...

Web 2.0

Simplicity

Open

So how can we find
simplicity and salvation?

Religion

But What Religion?

XML

VoiceXML and CCXML

Like Tribbles...

It has taken over the Enterprise...

But it’s kind of like
working for “the man”

So... How about API’s...

A Favorite of Carriers

Java

SIP Servlets
- Standard Java based API for
writing SIP applications.
- 1.0 standardized as JSR-116.
- 1.1 just released as JSR-289
- Extends the HTTP Servlet model
to support SIP and telephony
applications
- http://www.sipservlet.com/
- Supported by a large number of
application servers including
Oracle (BEA), IBM, Sun, Voxeo.

JSR-309
- Java Media Server API
- Based on the CCXML
media model
- Still in draft stage
- Provides dialog
resources,
conferencing, media
routing to Java
applications

Many Others...

But are they Simple?

Are they cool?

Frack No!

So...

Tropo.com

answer();
say("Hello, world!");
hangup();
Tropo is Simple

Ruby
Telephony in YOUR Language

•Accessible via Phone, SIP, Skype etc
•Inbound and Outbound calling
•Free for developers
•No setup costs
•Five minutes from sign-up to live deployment
+ = GO

How about some code?

T.1: Hello World
JavaScript and PHP Ruby
answer(); answer
say("Hello, world!"); say "Hello, world!”
hangup(); hangup
Python Groovy
answer() answer()
say("Hello, world !") say 'Hello, world!'
hangup() hangup()

Asking for Input - JavaScript
// -----------
// asking for input
// -----------
answer();
result=ask( "Hi. For sales, press 1. For support, press 2.", {choices:"1, 2"} );
if (result.name=='choice')
{
if (result.value=="1") { say( "sales is not available right now.") }
if (result.value=="2") { say( "support is currently on the other line." ) }
}
hangup();

Using ASR - Python
# Using speech input instead of touch-tone
answer()
result = ask("Hi. For sales, say sales. For support, say support",
{'choices':"sales, support", 'repeat':3})
if (result.name == 'choice'):
if (result.value == "sales"):
say("Sales is not available right now")
if (result.value == "support"):
say("Support is currently on the other line.")
hangup()

Using ASR and DTMF - JavaScript
answer();
result=ask( "For sales, just say sales or press 1. For support, say support or press 2.",
{ choices:"sales( 1, sales), support( 2, support)", repeat:3,
onBadChoice: function() { say("I'm sorry, I didn't understand what you said.") }
} );
if (result.name=='choice')
{
if (result.value=="sales")
{
say( "Ok, let me transfer you to sales." );
transfer( "14075551111");
}
if (result.value=="support")
{
say( "Sure, let me get support. Please hold." );
transfer( "14085552222");
}
}

Twitter Example - Groovy
answer()
if (currentCall.callerID == "8315551234") {
def event = ask("Welcome RJ. Please enter the phone number you wish",
[choices:"[10 DIGITS]",timeout:10])
if (event.name=="choice") {
transfer(event.value)
} else {
say ("too slow bro.")
hangup();
}
} else {
say("Thank you for calling RJ. We will connect you now.")
say("His twitter status is")
String xml =
"http://twitter.com/statuses/user_timeline.xml?screen_name=zscgeek".toURL().text
def strXML = new XmlParser().parseText(xml)
say(strXML.statuses.status[0].text.text())
transfer("tel:+18315551234")
}

Easy as Pie!

But wait, there’s more!

So...

Wrapping Up

So why is this important?

Quick Poll: Are you a phone
developer?

Phone Developers Web Developers
The Depressing Facts of Life

The Phone Developer
is DEAD!

THAT MEANS YOU

Don’t create phone applications...

Instead create applications
that use the phone...

Create Communication
Applications

Why?

Kids don’t talk on the phone
