Keep essential voice workflows moving with the Poly CCX 400 business media phone. Built for Open SIP deployments and powered over Ethernet, it fits cleanly into modern IP telephony environments where desk space, cable management, and call reliability all matter. This model is well suited for organizations standardizing on SIP-based communications and looking for a phone that delivers a focused user experience without unnecessary complexity. The CCX 400 is designed for teams that need fast access to calling functions, dependable network connectivity, and a professional desktop footprint. PoE support simplifies installation by reducing the need for separate power adapters, while the Open SIP design gives IT teams flexibility across compatible call control platforms. For procurement teams, that combination helps justify the spend: fewer accessories, cleaner deployment, and a device purpose-built for everyday business calling. Use it where voice is operationally critical — reception desks, shared workstations, service counters, and office environments that need a reliable endpoint rather than a consumer-style handset. The result is a phone that supports consistent communication, reduces desk clutter, and fits into enterprise telephony standards with less friction.
