Building Telephony Systems with OpenSIPS

Goncalves Flavio E. :
Flavio E. Goncalves was born in 1966 in Brazil. Having a strong interest in computers, he got his first personal computer in 1983, and since then, it has been almost an addiction. He received his degree in engineering in 1989 with a focus on computer-aided designing and manufacturing. He is also the CTO of SipPulse Routing and Billing Solutions in Brazil-a company dedicated to the implementing of small-to-medium telephone companies, VoIP providers, and large-scale new generation telephony systems. Since 1993, he has participated in a series of certification programs and been certificated as Novell MCNE/MCNI, Microsoft MCSE/MCT, Cisco CCSP/CCNP/CCDP, Asterisk dCAP, and some others. He started writing about open source software because he thinks that the way certification programs have worked is very good for learners. Some books are written by strictly technical people who sometimes do not have a clear idea on how people learn. He tried to use his 15 years of experience as an instructor to help people learn about the open source telephony software. Together with Bogdan, he created the OpenSIPS boot camp followed by the e-learning program, OpenSIPS eBootcamp. His experience with networks, protocol analyzers, and IP telephony combined with his teaching experience gave him an edge to write this book. This is the fourth book written by him. The first one was Configuration Guide for Asterisk PBX, by BookSurge Publishing, the second was Building Telephony Systems with OpenSER, by Packt Publishing, and the third was Building Telepopny Systems With OpenSIPS 1.6, by Packt Publishing. As the CTO of SipPulse, Flavio balances his time between family, work, and fun. He is the father of two children and lives in Florianopolis, Brazil-one of the most beautiful places in the world. He dedicates his free time to water sports such as surfing and sailing.E Goncalves Flavio :

Bogdan-Andrei Iancu entered the SIP world in 2001, right after graduating in computer science from the Politehnica University of Bucharest, Romania. He started as a researcher at the FOKUS Fraunhofer Institute, Berlin, Germany. For almost four years, Bogdan accumulated a quick understanding and experience of VoIP/SIP, being involved in research and industry projects and following the evolution of the VoIP world closely. In 2005, he started his own company, Voice System. The company entered the open source software market by launching the OpenSER/OpenSIPS project-a free GPL-SIP proxy implementation. As the CEO of Voice System, Bogdan pushes the company in two directions: developing and supporting. The OpenSIPS public project (Voice System being the major contributor and sponsor of the project) creates professional solutions and platforms (OpenSIPS-based) for the industry. In other words, Bogdan's interest was to create knowledge (through the work with the project) and to provide the knowledge where needed (embedded in commercial products or raw format as consultancy services). In the effort of sharing the knowledge of the SIP/OpenSIPS project, he started to run the OpenSIPS Bootcamp in 2008 together with Flavio E. Goncalves, which is intensive training dedicated to people who want to learn and get hands-on experience on OpenSIPS from experienced people. Bogdan's main concern is to research and develop new technologies or software for SIP-based VoIP (this is the reason for his strong involvement with the OpenSIPS project) and pack all these cutting-edge technologies as professional solutions for the industry.
