Our story

EVOX was created by D2 Nova in 2017 to move business communications to the cloud, but the story of EVOX goes back over twenty-five years, when David Wong and David Lindsay co-founded D2 Technologies Inc. to develop VoIP software for top tier manufacturers building a new generation of telecommunications equipment.  If you use VoIP, voice messaging, interactive voice systems, voice conferencing, an IP PBX, or an IP phone, chances are you have been using D2 software already.

With the advent of the cloud, David and David decided to re-deploy the VoIP technologies developed over the last three decades as a cloud service, thus D2 Nova and EVOX were born.


Our message to you

With EVOX, D2 Nova brings the technology it has been supplying the Telecommunications industry for the last three decades to the cloud so that it is available to more users, more easily, and more quickly.
