About this blog
BlogGeek.me is… Me. Blog. Geek.
This is a place for me for my rumblings about technology. It is where I go to think straight and to focus my mind on questions: questions I ask myself or questions I get asked by others.
About me
More specifically, this blog belongs to Tsahi Levent-Levi – that’s me with the geeky pretty face to the left. During the past decade (and then some) I have taken part in the development of various telecommunication projects – mainly those related to VoIP and 3G. I’ve done so as a programmer, manager, marketer and CTO. This included developing the 3G-324M protocol stack from scratch, as well as managing the team that was in charge of developing and maintaining the H.323 protocol stack, along with other interesting projects.
These days I am employed by Amdocs, dealing with innovation in the carrier space.
I have an MSc in Computer Science and an MBA degree with a focus in Entrepreneurship and Strategy. You can include in my resume a few patents and being the chairman of different activity groups in the IMTC – an organization focused on interoperability of multimedia standards.
I’ve got great two kids and a wife and I love cooking.
If you’re looking for some of my earlier writing, you can find it in various places:
- RADVISION’s VoIP Survivor blog
- NoJitter, as a “part-time” author

Hi Tsahi,
thanks for your articles. Its very informative and thought provoking….. I have been working on telecom projects for past several years and traveled many countries in Africa, Europe , Asia and North America. The change in the industry with the advent of smartphones is phenomenal. Perhaps webRTC is going the put the development in high gear.
Cheers,
Manoj
