Exciting Advancements in Open-Source

Telephony Applications in the Cloud

How many heard of Adhearsion before? How many heard of Tropo before?

Adhearsion

AsteriskAGI AMI

• AGI has no SIP-level control

• AGI is synchronous. Can’t cancel command.

• AMI protocol format has NO enforcement

• No good bridging API

• Simple features cause crashes (e.g. parking)

• features.conf is not dynamic

Asterisk Fun

Just to name a few!

It’s all for a good cause! Right???

There are just some things I can’t fix with

Most innovators

don’t careabout telephony

Hosting will maketelephony fun

(for once)

I set out to build an Adhearsion hosting

company

was following two nascent communities

FreeSWITCH

Java telephonyJSR 289, JSR 309, etc

then I found Voxeo

Adhearsion is now officially sponsored by

Voxeo

Jason Goecke and I have founded

Voxeo Labsin Silicon Valley

First major project:

Tropo.com

TropoToday

TropoTomorrow

Very much likeGoogle App Engine

will also supporta robust, high-level

Most of Tropowill be completely

open-source

What about Adhearsion?

• Adhearsion will have built-in Tropo protocol support

• Can always use a FOSS stack with it

• Don’t want to build a cluster? Use Tropo!

• Lots of new features coming!

• First cloud-friendly telephony application development framework

What to watch for• Telephony hosting will become FOSS-friendly

• New communities for pre-written, cross-engine open-source telephony applications

• The Java world will become an enormously important citizen in open-source telephony

• Adhearsion support for Tropo, FreeSWITCH, etc

• New protocols designed for app frameworks

• Influx of new talent from the web world
