Industry perspective sessions

Benjamin Wolf, BASIS Audionet - "High availability VoIP environment with geographic redundancy"

Bogdan-Andrei Iancu, Co-Founder OpenSER & CEO Voice System - "The challenge of service diversity"

A walk trough VoIP scenarios, from simple service provider case up to complex carrier grade cases, with a deep analysis of functionalities variety. The presentation will highlight the challenges and traps of features and business cases blending, providing a glim over the possible solutions.

Daniel-Constantin Mierla, Co-Founder OpenSER & CTO Voice System - "OpenSER History"

In the opening of the event, after introduction of special guests and relevant OpenSER community members, follows the history of OpenSER: how it started, what was achieved so far, challenges as milestones in the past. You will be able to see and meet people behind the scene, hidden by the email address or forum nickname and get the truth about the project's evolution.

Dean Elwood, VoIPUser - "VoIPUser - community driven VoIP services"

VoIPUser.org is the famous VoIP forum site which offers VoIP services to members. It is an open community where the availability of VoIP services is guided by user itself.

Elias Baixas, VozTelecom Innovation Engineer - "Development of convergent J2EE applications for OpenSER"

A brief SIP servlet development tutorial showing the application development cycle, the HTTP-SIP protocol interaction and main coding techniques and samples.

This track will consist of a brief SIP servlet development tutorial. A real world application example will be used as the vehicle to provide an overview of OpenSER development with WeSIP. The main topics covered will include Application development and deployment, HTTP-SIP protocol interaction, Session information and management, operational modes (UAC,UAS,Proxy and B2BUA) and access to J2EE resources like databases,email or other Java APIs among others.

An introduction to SIP Application Servers and their role in SIP networks as well as the presentation of WeSIP, a converged application server for OpenSer based on SIP servlet industry standard.

SIP Application Servers play an important role in SIP networks facilitating the development and deployment of new features. WeSIP is a J2EE SIP Application Server that implements the SIP Servlet specification and integrates with OpenSER. Using WeSIP you can develop convergent HTTP/SIP applications for your OpenSER SIP network using the java development platform. In this track we'll introduce the J2EE SIP Application Servers, the OpenSER/WeSIP architecture and highlight the benefits that it can bring to entities running OpenSER.

James Body, Truphone - "GetTru - bring VoIP to your mobile"

Truphone is a brand new piece of free software that brings VoIP to your mobile. That means free mobiles calls to other Truphone users or very cheap calls to anyone else. You will get a broad view of technology behind, how it can change your mobile phone bill and the innovative features that come with the service.

Joachim Fabini, Vienna University of Technology - "OpenSER-based IMS. Experiences and Perspectives"

A look at the architecture of an OpenSER-based IMS testbed and our experiences gained
during the concept and implementation phase. By means of OpenSource-based traffic generators and WAN emulators we can simulate different IMS topologies and test IMS prototypes on reliability and robustness. We conclude with our perspectives on the future of IMS and its impact on free IP-based telephony.

Klaus Darilion, Enum.at - "Practical peering with OpenSER"

- What is VoIP peering? Who needs it? Security and trust relations.
- "Open" Peering (e.g, FreeWorldDialup, ...) vs. "Closed" Peering (e.g, SipGate ...)
- Statical peering (priority knowledge, connection parameters)
- Dynamical peering (ENUM, I-ENUM, no priority knowledge (federations), connection parameters)
- Usage of the domain peering policy

Philippe Sultan, INRIA - "INRIA - VoIP deployment notes"

INRIA has joined Internet2 SIP.edu initiative to offer its users the ability to be joined from a growing SIP network, and to help them getting familiar with VoIP tools. About 5000 email addresses and PBX extensions are reachable from the Internet. This covers the users of every Research Units (located in different French cities) that are part of INRIA. Internet2 SIP.edu network interconnects many famous world wide Universities and Research Institutes: MIT, Yale, Harvard, INRIA, ...
