Why does Zfone offer two licenses?
Zfone’s dual license model supports the company’s mission: to make superior secure VoIP software available and affordable to all, and to make money doing it. The dual licensing creates a circle that sustains both innovation and growth: Zfone channels the revenue from this viable open source business model back into software development that, in turn, supports Zfone’s commercial business. Zfone’s open source community gets superior software for no cost, while Zfone’s commercial customers have the option of using reliable, peer reviewed, community tested Zfone software for a relatively low cost.
