Unified IP PBX for up to 1000 users

The Grandstream UCM6302 is a unified communications platform that centralises voice, video calling, conferencing, surveillance and facility access on a single network. It supports up to 3000 users and 450 concurrent calls, making it suitable for growing businesses that need a scalable on-premise solution without per-seat licensing fees.

Check analog lines and network ports before ordering

This unit provides two FXO ports for PSTN trunk connections and two FXS ports for legacy analogue devices such as fax machines or cordless phones. Verify that your incoming line count matches the two FXO interfaces and that your analogue extensions do not exceed the two FXS ports. The appliance also includes three Gigabit RJ45 ports with PoE+ for network integration and router functionality.

Replaces standalone phone systems

Organisations moving from a traditional PBX with limited analogue ports or a disjointed mix of hardware and cloud meeting services can consolidate onto this platform. The jump is worthwhile when you need zero-configuration provisioning for Grandstream endpoints, a built-in meetings platform accessible via Wave apps and browsers, and API hooks for CRM or PMS integration — all secured by secure boot, unique certificates and randomised default passwords.

Questions about this item

What accessories are included with the UCM6302 and what must be purchased separately?

The UCM6302 ships with the IP PBX appliance, three Gigabit RJ45 ports with integrated PoE+, and the built-in Wave collaboration platform. SIP endpoints, phones, and any additional network cabling are sold separately.

How do I decide between the 1000-user and 3000-user capacity ratings?

The UCM6302 supports up to 1000 registered users and 450 concurrent calls; the higher 3000-user figure applies to other models in the UCM6300 series. Choose based on your peak simultaneous call volume and total extension count.

What does the 450 concurrent-call figure mean for daily office use?

It means the system can handle 450 active voice or video calls at the same time, so a typical office with dozens of simultaneous conversations will run well within the UCM6302's capacity.
