Originally founded in 2001, Zultys was a pioneer in voice over IP technology, being one of the first companies to deliver a truly SIP-based PBX to the market. Despite the market’s slow adoption of SIP, the vision for Zultys to create and deliver a truly innovative IP Communications System burned brightly. The company continued to grow while massive investments into research and development drove a singular focus to design and build the best, most reliable, innovative and efficient IP PBX available to small and medium-sized businesses. Zultys is headquartered in Silicon Valley with offices around the world.
