I juggled my Kagiso work with freelance work for Sudonum, a company specializing in all sorts of API's for calling, be it from their own pseudo(sudo)numbers they give out to users, clients or businesses, or with real cellphone numbers.

The owners, Mike and Mark, ex-colleagues of mine from Mxit days, called me up to start working for them on creating a mobile (Android first and then iOS) and web library that is essentially a "click-to-call" button that can be embedded into any app or website which will enable you to make a free VoIP call to a number using WebRTC as the communication platform.

This is very interesting work for me especially as WebRTC is growing so much. Work is still going to continue on this on a freelance basis in 2018.
