What is the UCM6300 Ecosystem?


The UCM6300 ecosystem pairs together the customization and control of an on premise IP PBX with the remote-access of a cloud solution to provide an easy-to-manage hybrid communication platform for businesses of all sizes. Together, the UCM6300 series, UCM6300 Audio Series, UCM RemoteConnect and Wave provides any organization with a powerful, easy-to-manage and flexible communication and collaboration solution

This solution bundle elevates the UCM6300 Series & UCM6300 Audio Series IP PBXs to easily and securely reach outside of the on-site network to support remote workers. When utilizing UCM RemoteConnect, a cloud-based service through the Grandstream Device Management System, the ecosystem provides a companion cloud service for the UCM6300 series that provides always-on, automatic NAT firewall traversal to ensure secure connections by remote users.
