Upgrading meeting room technology does not require a complete migration to IP or cloud systems. Digital and legacy system conference phones connect directly to existing extension ports—such as digital PBX lines or analogue extensions ensuring immediate integration with your current call routing and line setups.
Designed specifically for meeting spaces, these units feature advanced 360-degree microphone pickup, echo cancellation, and full-duplex technology. This ensures every participant around the board table is heard clearly, eliminating the muffled audio and dropped sound typical of standard extension handsets.
We stock original and refurbished conference hardware compatible with major system protocols, including:
Polycom / Poly: Industry-standard SoundStation conference units for analogue and digital PBX lines.
Avaya: Dedicated system conference phones designed for seamless integration with Avaya PBX platforms.
Mitel & Siemens: Reliable conference units engineered for digital office environments.
