IP PBX Systems

The UCM series of IP PBXs offer an extensive set of unified communication features in an easy-to-manage on premise solution with no licensing fees. Our UCMs range from small and medium business deployments to small and medium enterprise solutions.

Grandstream offers several IP PBX platforms for unified communications and collaboration. The UCM Series are license-free, on-premises IP PBXs that give a customizable UC platform. UCM RemoteConnect pairs with the UCM6300 Series to combine the benefits of on-premises and cloud PBXs in one secure, easy-to-manage setup.

CloudUCM is Grandstream's cloud PBX, a scalable business communication and collaboration platform with built-in features and integrations, and SoftwareUCM is a software-based PBX. The free Wave app gives users mobile, desktop and web clients for communicating from almost any device, and it pairs with the UCM6300 Series, UCM RemoteConnect and CloudUCM. Grandstream's wider range includes IP phones, ATAs and gateways, conferencing, networking gear and convergence products. It suits MSPs that sell voice systems and want a choice of on-premises, hybrid or cloud PBX from one vendor.
