Unified communications hub

The Grandstream UCM6302 is an on-premise IP PBX appliance that unifies voice, video calling, video conferencing, video surveillance, web meetings, data, analytics, mobility, facility access and intercoms on one centralised network. It supports up to 3000 users and up to 450 concurrent calls for businesses that need a single platform for all communication channels.

Ecosystem integration

Zero-configuration provisioning connects Grandstream SIP endpoints automatically, while the built-in conferencing platform works with desktop clients, the Wave app for Android, iOS, Chrome and Firefox, and SIP endpoints. An API enables third-party integrations with CRM and PMS platforms, and GDMS provides cloud setup and management alongside the UCM RemoteConnect NAT traversal service for secure remote access.

Port density constraint

Three Gigabit auto-sensing RJ45 network ports with integrated PoE+ and NAT router support define the physical connectivity limit, so buyers needing more than three wired uplinks or separate PoE budgets must plan additional switching infrastructure.

Questions about this item

How often should the internal fan be cleaned or replaced on the UCM6302?

The appliance has no user-serviceable fan; keep the vents clear of dust and operate it in a ventilated rack or shelf for reliable long-term use.

What is the first limit reached under continuous heavy call load on the UCM6302?

The system caps at 450 concurrent calls; beyond that new calls are blocked until active sessions drop below the limit.

How much power does the UCM6302 draw and how warm does it get when running all day?

Three Gigabit RJ45 ports with integrated PoE+ supply up to 30 W per port; the chassis stays cool with passive convection when mounted with space around it.
