IP PBX for up to 1000 users

The Grandstream UCM6300A is a desktop or wall-mount audio IP PBX that supports up to 1000 users and 200 concurrent calls. It provides four FXO ports and four FXS ports for connecting analogue lines and devices. The system runs on Asterisk version 16 and offers zero-configuration provisioning for Grandstream SIP endpoints.

Passive cooling with PoE+ ports

The unit measures 8.19 x 15.04 x 2.44 inches and weighs 2.73 pounds with no moving parts, so it operates silently in an office or server room. Three Gigabit auto-sensing RJ45 ports include integrated PoE+ to power compatible phones and accessories directly. An automated NAT firewall traversal service helps maintain secure remote connections without extra hardware.

Wave app and GDMS cloud management

The free Wave app extends voice and instant messaging to desktop, web, Android and iOS clients. Built-in instant messaging, audio conferencing and web meetings run on the appliance itself. An open API enables integration with CRM and PMS platforms, while GDMS compatibility allows cloud-based setup, monitoring and ongoing management.

Questions about this item

How do I install the Grandstream UCM6300A and what step do people often miss?

Mount the unit on a desktop or wall, connect the three Gigabit RJ45 ports for LAN, WAN and PoE+ devices, then plug the four FXO lines and four FXS extensions; the step most often missed is enabling the automated NAT firewall traversal service so remote phones register without manual port forwarding.

What maintenance or replacement will the UCM6300A need over time?

The appliance has no user-replaceable fan or battery; plan on firmware updates through the web UI or GDMS cloud platform, and replace the external power supply only if it fails.

Which limit appears first when the UCM6300A runs at sustained load?

The system caps at 200 concurrent calls or 1000 users in this audio-only configuration, so call capacity is the first ceiling reached during heavy traffic.
