The HP Poly CCX 400 is part of Poly’s CCX series of media phones, designed for modern workplaces where a touch-enabled interface makes daily communication faster and more intuitive. The 5-inch color touchscreen is responsive and spacious, making it easy to manage calls, contacts, and voicemail without reaching for a separate device. This version runs Open SIP firmware, making it compatible with a wide range of third-party hosted and on-premises VoIP platforms. HD Voice keeps audio quality high on every call, and the phone’s clean, minimal design fits well in any professional setting. The included power supply means it can be deployed without a PoE switch, broadening its usability across different office environments. The CCX 400 is a strong choice for organizations that want a modern, touch-first desk phone experience without locking into a specific vendor ecosystem. It is well-built, easy to use, and brings a level of polish to the desk that older button-based phones simply cannot match.
