The AudioCodes C456HD is a native Microsoft Teams desk phone specifically designed for organisations with high requirements for security, management and reliability. Combining Android 13 MDEP, integrated Wi-Fi 6 and a dedicated emergency call button, it is particularly well suited to educational institutions, public sector organisations and professional business environments.
The C456HD supports native Microsoft Teams operation with calendar integration, presence status, corporate directory access, voicemail functions and one-touch participation in Teams meetings. Dedicated tabs for calls, calendar, contacts and voicemail simplify day-to-day work.
The phone is based on Android 13 MDEP (Microsoft Device Ecosystem Platform), providing enhanced security and management capabilities. The integrated emergency call button improves safety in classrooms, public institutions and workplace environments. In addition, the hardware microphone mute function prevents unwanted audio capture.
The 5-inch TFT colour touchscreen with a resolution of 1280 × 720 pixels enables intuitive operation. For users with high communication volumes, an optional expansion module with a 5-inch high-resolution touchscreen is available. This supports up to 60 speed-dial contacts as well as call transfer, consultation, shared line and call queue functions.
With dual Gigabit Ethernet ports, integrated dual-band Wi-Fi 6, USB headset support and PoE technology, the C456HD is designed for modern business networks. Centralised management is available through AudioCodes Device Manager and the Microsoft Teams Admin Centre. Zero-touch provisioning simplifies deployment across the organisation.
The AudioCodes C456HD has been specifically designed for educational institutions, government organisations, healthcare facilities and businesses that place particular emphasis on security and ease of management.
