Customers
Customers of the Zfone client software
The Zfone client software has been downloaded by many thousands of users from our web site since the first beta release in May 2006. It's still in public beta, which means it's still free until the full release.
Customers of the Zfone libZRTP SDK library
We also license the Zfone libZRTP SDK on an OEM basis to companies that want to add the ZRTP protocol to their VoIP products. There a growing number of companies and products that have plans to incorporate our protocol, including Borderware, Counterpath, Digium, and quite a few others, some of them major companies that are not quite ready to announce yet. Take a look at a few of them on our Partners page.
