Unified communications appliance

The Grandstream UCM6301 is a 1FXO 1FXS VoIP IP PBX that supports up to 3000 users and up to 450 concurrent calls. It is designed for businesses that need an on-premise unified communications platform with integrated telephone interfaces. Zero-configuration provisioning works with Grandstream SIP endpoints to simplify deployment.

Integrated collaboration and connectivity

Built-in conferencing and a meetings platform support desktop clients, the Wave app and SIP endpoints. Wave runs on Android, iOS, Chrome and Firefox so users can communicate across devices. An API enables third-party integrations with CRM and PMS platforms. Three Gigabit RJ45 ports include PoE+ and NAT router support, while automated NAT firewall traversal assists secure remote connections.

Capacity limits and constraints

The system handles up to 3000 users and 450 concurrent calls, which suits small to mid-sized organisations. It provides one FXO and one FXS port, so sites that require more analogue trunk or extension connections will need additional hardware. Advanced security features such as secure boot, unique certificates and random default passwords protect calls and accounts.

Questions about this item

Will the FXO or FXS ports on the UCM6301 need periodic replacement?

The UCM6301 has one FXO and one FXS port built into the appliance; these are solid-state interfaces with no moving parts and no user-replaceable modules, so no scheduled port replacement is required.

What limits concurrent call capacity on the UCM6301 during sustained use?

The system is rated for up to 450 concurrent calls; once that threshold is reached, new call attempts will be blocked until active sessions drop below the limit.

How much heat and power does the UCM6301 generate when running continuously?

The unit uses three Gigabit RJ45 ports with integrated PoE+ and has no internal fan, so it operates silently with minimal heat output suitable for desktop or rack mounting.
