Partnership Overview
Who Zultys is built for
SMB and mid-market organizations (10-500 users) that want a feature-rich on-premises or hybrid IP PBX with channel-delivered implementation; verticals that prefer to own infrastructure (healthcare, manufacturing, government, education).
Zultys is a U.S.-based provider of all-in-one IP phone systems and unified communications, headquartered in Sunnyvale, California. The company sells the MX series of on-premises IP PBXs and ZAC (Zultys Advanced Communicator) softphone for SMB and mid-market customers via a channel partner program. Zultys differentiates with a single-box appliance approach that includes voice, messaging, presence, contact center, mobility, and faxing, simplifying deployment for organizations that prefer on-prem or hybrid voice. Recent releases (R18/R19) added cloud connectivity, MS Teams integration, and modernized desktop/mobile apps.
