Scalable IP PBX for mid-sized businesses

The Grandstream UCM6301 is an on-premise IP PBX appliance designed for organisations that need a unified communications platform without recurring cloud fees. It supports up to 3000 users and handles voice, video calling, conferencing, surveillance and facility access on a single network.

450 concurrent calls with FXO and FXS ports

The system manages up to 450 simultaneous calls and provides one FXO port for PSTN trunk connectivity plus one FXS port for analogue devices such as fax machines or legacy phones. This capacity suits branch offices or SMEs; larger deployments requiring higher density or additional analogue lines will need a different model.

Three Gigabit PoE+ ports and automated NAT traversal

Three auto-sensing Gigabit RJ45 ports with integrated PoE+ power compatible endpoints directly, while the built-in NAT router and automated firewall traversal service enable secure remote connections without manual port forwarding. Advanced security features include secure boot, unique certificates and randomised default passwords.

Questions about this item

Will the 1 FXO and 1 FXS ports on the UCM6301 connect my existing analogue phones and PSTN line?

Yes. The single FXS port connects an analogue phone or fax, while the single FXO port links to a traditional telephone line, letting you keep legacy devices alongside the IP PBX.

How can I verify the UCM6301 is handling calls correctly after installation?

Place test calls between the analogue port, a registered SIP phone and an external number; check the web interface call-status page for active sessions and review the CDR logs for completed calls.

What ships with the UCM6301 and what must I source separately?

The appliance includes the UCM6301 unit, power adapter and rack-mount brackets. You must supply Ethernet cables, SIP endpoints or softphones, and an analogue phone or PSTN line for the FXS and FXO ports.
