Twilio provides infrastructure APIs for businesses to build scalable, reliable voice and text messaging apps.

The Twilio Conference happens Wednesday, September 21, 2011 at 8:00 AM – Thursday, September 22, 2011 at 6:00 PM (Pacific Time) in San Francisco. Here’s a discount offer.

You may recall we talked about Twilio’s OpenVBX almost exactly one year ago.

Cloud based telephony is becoming a ubiquitous new frontier of development for companies in this space. Recently, a blog post called “Why choose Tropo over Twilio” written by Tropo’s Chief Technology Evangelist (and Voxeo Co-Founder), Johnny Diggz, hit the front page of Hacker news over the weekend.

Comments on the new site erupted to a level just short of a flame war between the “super-angel” backed startup, Twilio, and Voxeo/Tropo.  Diggz will be joining VoIP Users Conference to talk about his role in this battle for the hearts and minds of a new wave of developers in cloud-based telephony.

Twilio’s Evan Cooke responded to our (sorry, belated, my bad) invitation and talks about Twilio.

OpenVBX is a web-based open source phone system for business.
With a Twilio account and a web server with PHP 5.2+ and MySQL 5, you can build your own “hosted pbx”.

Build your own custom phone applets with just a little bit of PHP. Rebrand and resell OpenVBX to your customers.

Give every user their own phone number and personal conference line. Dial whole departments, share voicemail messages with the team. OpenVBX is for companies and collaboration.

Adam Ballai, lead engineer on the OpenVBX project and Twilio CEO Jeff Lawson are our guests.

Quickfuse offers a graphic interface which allows you to drag and drop your way to a full-featured IVR application and have a working prototype in minutes.

Quickfuse incorporates access to data, logic and branching, instant visual feedback and a free trial account.

Thanks to Dave Michels, who met him at Glue Con, Twilio CEO Jeff Lawson and CTO Evan Cooke join us to discuss their “cloud telephony” offering. You can prepare by getting a free account and checking out what can be done with the platform. Note that speech to text (transcription) is a part of it.

“Twilio provides an in-cloud API for voice communications that leverages existing web development skills, resources and infrastructure.”

Twilio are giving away a free netbook book each week to developers that build cool voice applications: http://www.twilio.com/contest/netbook/

Jeff Lawson will be speaking at OSCon July 20-24th later this month about open source, telephony, and Twilio.
