Understanding and Troubleshooting SIP

I am getting old and curriculums are one the most boring things I’ve ever read and most of them do not really show who you are. So, my creative curriculum is below.

I was born in 1966 in the beautiful city of Poços de Caldas, a thermal spa. The city is a great source of radioactive materials such as Uranium and Thorium. This may explain some things.

I live in the sunny island of Floripa, Brazil, the single most beautiful place in the world, married since 1988 with Clarice and father of Anna (28) and Pedro (32).

I’m a geek, entrepreneur and surfer, not necessarily in this order. With surf I learned a lesson, practice does not always lead to perfection!

My first technical achievement in life was to replicate the Start Trek’s Gorn Cannon in 1980. Something Myth Busters fail to do in 2009. Always loved fireworks and gunpowder.

In 1981 I did the Kubrick’s cube. When there was no Internet or instructions.  I discovered myself as pretty persistent type of stupid.

I got my first computer in 1982 and as any oldie loves to show off, it was a also zx80 with 16k of ram. It received a bite in the left corner of the keyboard when it froze running a flight simulator I'd spent 10 hours typing.

In 1983, for the wrong reasons, I got into the Mechanical Engineering. The department had the best computers at that time. However, computer scientists are still not convinced that I can code.

After graduating in 1989, for the wrong reasons, I got a job in IT. The air conditioning on IT was much better than the one in the factory floor. I worked as a support analyst, network, and database administrator. I learned SQL at that time, the single most valuable training I have ever had. It is still very useful even after 30 years.

In 1993 I founded a Novell Education Center and became Master CNE and Master CNI. I owe Novell everything I know about teaching classes and provide training. What they did in the 90’s was groundbreaking in the industry and still a reference

In 1996 I founded my first company V.Office. A Cisco Integrator. One of my best decisions, we still have a large base of customers. Now after 25 years, 6 dozen professional tests and certifications such as CCNP/CCDP, CCSP and CCIE written, the company is a success and run almost by itself.

In 2006, for the wrong reasons, I have started a series of ventures related to VoIP and Asterisk. I wrote a book and training on Asterisk. The motivation was I had finished my house and was almost broken. I wanted to replace my old surfboards and tennis rackets. The books and training were not only enough to replace the sport goods but to furnish the whole house. By the way, my wife loves Asterisk.

In 2008 with the help of my Jedi friend Bogdan Iancu I wrote the book “Building Telephony Systems with OpenSER”, later updated to OpenSIPS. Together we have launched the OpenSIPS Bootcamp and the OpenSIPS Certified Professional certificate.

In 2010 after several years running IP PBXs, I decided to start a new company called SipPulse to develop soft-switches and high-volume telephony. SipPulse is one of my biggest successes having more than 300 active customers. I have been always a good person to start a company, but a terrible one to manage. It is now being managed by a professional administrator and doing very well.

In 2016, for the wrong reasons, I started teaching on Udemy. I just wanted to have an extra account to finance my surf trips to Indonesia. The Complete Asterisk Training and Understanding and Troubleshooting SIP were a success. I scored my first barrel in my last season in the Mentawai’s Islands, thanks to all my students.

This year, 2021 in the middle of the pandemic, for some wrong reason I didn’t figured out yet, I have started two new ventures voip.school and wehostvoip for VoIP hosting

After this “sincerecide” I hope you still want to do my trainings. I’m trying at least to make my courses a little more fun than the usual power point torture.
