The Grandstream UCM6304A IP PBX is a powerful audio-only unified communications (UC) appliance designed for small to medium enterprises that need a fully integrated on-premise phone system with collaboration features. It is part of the UCM6300 Audio Series, offering voice, messaging, conferencing, and system integration in a single platform.
This model supports up to 1,000 users and 150 concurrent calls, making it suitable for multi-department business environments, call centres, and organisations requiring scalable telephony infrastructure.
It also includes 4 FXO ports and 4 FXS ports, allowing direct integration with traditional analogue lines and devices while supporting modern SIP trunking and IP endpoints.

It supports built-in audio conferencing, instant messaging, and web meetings, helping teams collaborate without third-party subscriptions or per-user licensing fees.
With built-in remote access tools (including Grandstream Wave support), it also enables secure hybrid working across desktop and mobile devices.
