Mobicents TelScale and RestComm
FOSDEM 2012
About Me - Jean Deruelle
● OpenSource @ Heart
● Mobicents Core Contributor and Sip Servlets/TelScale
project Lead
● TeleStax Co-Founder
Agenda
● Telco Evolution towards Telco 2.0
● RestComm
● TelScale
Traditional Telcos
● Typically seen as slow Innovators
● Network centric as opposed to User Centric
● Revenues coming from SMS, Voice and broadband services mostly
The Pains of Traditional Telco Service Development
Cloud Happened
● Moving slowly to an all IP World.
● OTT Players are around the corner, need to find new sources of revenue.
● Convergence of Web and Telco Services is now possible
● Not much success in generating new revenues from the convergence of Web and Telco World
● Carriers still entranched in their good old ways, Parlay-X anyone ? Moving to GSMA OneAPI initiative
Cloud Notions
Disruption has come quickly
● Twilio provides infrastructure APIs for businesses to build scalable, reliable voice and text messaging apps
● Tropo Adds Voice, SMS, Twitter and IM to Your Applications
=> Telco 2.0 Public SaaS (Software as a Service)
Telco 2.0 SaaS Advantages
● App Developper/User Centric
● Foster availability of innovative new services => Web/Telco 2.0 Mashups
● Lower Barrier to entry : No need for skilled telecom engineers anymore when telecom is not your core business => Plug n Play
● Embed Telco capacities in any connected device, no matter if it’s a smartphone, an app, a PC, a tablet, a connected car, a TV, ...
● Scale on Demand
● Creates new kind of revenues
○ Allows revenue sharing model for app developers
○ Pay developers for their usage (BlueVia from Telefonica)
Is there a need for a Telco SaaS in a private/hybrid cloud ?
● Avoid Vendor Lock-in
● Global Service Availability
● Data Privacy
● Mature through USAGE the APIs that WORK
Welcome RestComm
SaaS Ready
Web / MobileApplicationDeveloper
Introduction to RestComm
● RestComm is to Twilio/Tropo what Eucalyptus is to Amazon (and offers 100% API Compatibility with Twilio/Tropo + extensions to it)
● RestComm is a communications platform that
empowers developers to rapidly create Fax, Voice, (Video soon), SMS, and MMS enabled applications.
● RestComm is being developed as an open source project for deployment on private, public, and hybrid clouds.
How does RestComm work ?
A call is made to RestComm RestComm requests XML Instructions
Your application returns XML Instructions
RestComm executes the XML Instructions
