Jose de Castro from Voxeo Labs subsidiary Tropo took the stage after John, to welcome everybody to the conference and to announce a new application they were releasing that morning. Tropo provides an engine for online voice, SMS and twitter communication, and their newest project is called PhonoSDK. Phono is a jQuery plugin that can turn your browser into a JavaScript-based phone, capable of calling another browser or even a landline. The SDK is being provided as a service, and is already powering Facebook Telephone—a blog post about that program is also available on Phono’s site. The forums lit up as soon as the jQuery Boston attendees saw how simple Phono was to set up, and I expect we’re going to see a lot of new Phono apps in the next few weeks. Well launched, Tropo!
