We started Sipfront in 2020 to bring honesty and clarity to a world where communication is getting faster and more complex every day. Our founders Andreas Granig, Daniel Tiefnig, and Markus Seidl built this company to be the independent truth layer for the modern voice era. While Sipfront is a fresh response to the rise of AI, our roots go back decades.
A shared History in High-Stakes Voice
The architects of Sipfront didn’t just join the industry; they helped build it. Having previously founded and scaled Sipwise, our team brings over 25 years of experience in the carrier-grade market to every test we run. This means that while our tools are modern and agile, they are built with the technical maturity needed to support the world’s largest telecom operators and enterprises.
We invented the Silent Standards
If you have made a call today, there is a pretty good chance you have used our work without noticing it. Our team serves on the Kamailio management board and created the rtpengine project. Today, rtpengine is the silent engine powering the media paths of the world’s biggest UCaaS and CCaaS providers. It is also the foundation for the infrastructure used by leading Voice AI vendors. When we talk about how voice travels, we are talking about the architectural logic we helped establish for the entire industry.
An international Team of Experts
Sipfront is a quickly growing international team of engineering and business development experts who truly know the telco and Voice AI landscape. Because we have deep ties into the UCaaS and CCaaS worlds, we don’t just see numbers on a screen. We understand the business reality and the operational challenges you face every day.
Our Purpose
We believe that as communication evolves, the verifiable truth of quality must remain transparent. We bridge the gap between digital logic and the human ear, making sure that every interaction, no matter how complex, is delivered with absolute clarity.
Based in Vienna, Austria, Sipfront supports a global network of operators and AI innovators.
