“Just finished the class here in Orlando and we met people from Peru, Colombia, USA and Canada. It was a nice gathering and everybody left with strong feeling of satisfaction.

I never had installed Kamailio (OpenSER) before and we had the guts of a carrier-class architecture worked-out and prototyped in one day. Seldom does a class gives you a career boost of such magnitude.

Merci beaucoup to Daniel and Olle for caring to share their incredible knowledge.“
