Stay connected anywhere in your workspace with the Snom M400 DECT Base Station. This powerful single-cell DECT base (easily expandable to dual-cell) gives your team true cordless f reedom without sacrificing call quality or security. Perfect for small to medium offices, retail stores, warehouses, or hybrid work environments where employees need to move freely while staying reachable on high-quality VoIP calls. With support for up to 20 handsets and up to 20 parallel calls in dual-cell mode, plus easy zero-touch setup for cloud or on-prem PBX systems, the M400 delivers enterprise-grade performance at a price that makes sense for growing businesses. The Telecom Spot Expert Review The Snom M400 is a smart, future-proof choice for any team that needs reliable wireless phones without the complexity (or cost) of a full multi-cell system. What stands out most is how it balances simplicity and scalability: start with one base for basic coverage and add a second base anytime to create a dual-cell system that doubles your call capacity – no rip-and-replace required. It shares the same rock-solid architecture and security updates as Snom’s flagship M900 multi-cell system, so you’re not locked into an entry-level dead end. Crystal-clear wideband (HD) audio even when walking around Super-simple web interface and zero-touch provisioning that cloud/VoIP partners love Strong security (TLS & SRTP) right out of the box Wall-mountable, compact design that blends into any office Expert Take: If you have 5–20 mobile users who need to roam between the front counter, warehouse, or break room, the M400 hits the sweet spot. It’s not overkill like a full multi-cell solution, yet it grows with you. We’ve seen customers in retail and light manufacturing love the seamless handover and long battery life on the compatible M-series handsets. Just pair it with Snom M30, M70, or M85 handsets and you’re up and running in minutes.
