Kamailio World 2018 is coming!

Posted . ~2min read.

It’s not too late to make plans to visit Berlin this May and join us at Kamailio World 2018.

Kamailio World allows Kamailians, VoIP enthusiasts, and more to Connect, Inspire, and Create during an amazing conference. Last year, Yeni and I flew out for the first time and I only regretted not attending before.

I am lucky (and honored) to attend many VoIP conferences throughout the year and Kamailio World is on my must attend list for a simple reason— the ability to connect with this amazing community will inspire you to create something amazing.
