Building the open communications platform
We help carriers, resellers and enterprises run their own voice infrastructure on proven open-source technology—without proprietary lock-in. More than 15 years of VoIP engineering, in one platform you actually own.
Open standards, by conviction
VOIXYS grew out of more than 15 years spent building and operating voice networks—wholesale routes, hosted PBX deployments and real-time billing for operators across Europe and North Africa. Along the way we saw the same problem repeat: teams locked into closed softswitches they could neither audit nor extend.
So we built our platform on the engines we already trusted in production—Kamailio for SIP signalling, FreeSWITCH for media and Class 5 features, and CGRateS for rating and billing. The result is a carrier-grade stack with no proprietary API in the signalling, media or billing path. Your rate plans, your CDRs and your data stay yours, whether we host it for you or you run it on your own servers.
