Our Story

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.

That effort paid off! With the core belief that ‘high performance doesn’t have to be highly complex’, the MX platform remains the focus and the foundation of the Zultys Business Communications Systems platform today and includes the most comprehensive offering of unified communications and contact center capabilities available.
