Centile was founded in 1998 in Sophia Antipolis, France, Europe's largest technology park. It's a subsidiary of ViaOne Europa and former R&D Center of 8x8, Inc.

Centile is a global leader in the development and commercialization of VoIP and Unified Communications solutions. Centile can claim one of the earliest and most intensive R&D efforts in VoIP. Their flagship Istra platform is the end result of this unprecedented drive that included an initial 6 year, €40 million investment in R&D. Istra empowers Service Providers, Mobile Operators and Large Enterprises to deliver advanced VoIP and Unified Communications features transparently via any broadband network.
Since its creation in 1998, Centile has focused on developing and delivering versatile VoIP and Unified Communications solutions by strongly embracing and investing in:
• Open-standards including SIP
• Pure IP communications
• A fully software-based solution based on Java and Web technologies

Centile was responsible for some of the earliest commercial deployments of IP Centrex solutions (starting in 2000) and since then has gained exceptional global operational experience with these systems. They have also witnessed and contributed to the progressive evolution of SIP related standards over the years, which now clearly offer them the benefits of a suitable level of interoperability.
