Poly CCX 505 Corded Business Media IP Phone with Power Supply (Open SIP)

The Poly 84C16AA#ABA is a business media IP phone that combines a vibrant 5 inch color touchscreen with advanced audio and flexible network options to keep calls clear and workflows smooth. Designed for open SIP deployments, it slots easily into most cloud or on-premises VoIP services, making it a dependable desk companion for offices, shared workstations, and remote setups that need reliable voice quality.

Navigating the phone feels intuitive because the touchscreen mirrors the tap-and-swipe gestures people already use on their mobile devices. You can scroll through contacts, review voicemail, or join a scheduled meeting without hunting for physical buttons, which helps reduce call setup time and keeps your focus on the conversation.

Connectivity is where the CCX 505 stands out. Dual Gigabit Ethernet ports handle high-speed wired data while supporting Power over Ethernet for cable-free power in PoE environments. Built-in Wi-Fi 4 lets you place the phone where network cabling is limited, and Bluetooth 4.2 pairs quickly with wireless headsets or a mobile phone for easy call handoff. Two front-facing USB ports, one USB-A and one USB-C, keep wired headsets, flash drives, or future accessories within reach.

Audio clarity remains at the heart of every Poly device. Poly HD Voice delivers full-band sound that helps you catch every detail, and Acoustic Fence technology filters distracting background noise so your callers hear you, not the office chatter. Poly Acoustic Clarity further reduces echo and sidetone, creating a more natural, fatigue-free conversation during long call sessions.

For teams that juggle several numbers, the phone supports up to 24 SIP registrations, letting a receptionist, executive, or power user manage multiple lines, direct calls, or monitor colleagues’ status from one device. The handset is hearing-aid compatible and meets ADA volume requirements, so it is a practical choice for accessibility-focused workplaces. An optional wall-mount kit expands placement possibilities in huddle rooms, customer counters, or healthcare stations.

Whether you are equipping a fast-growing startup, upgrading branch offices, or giving hybrid workers a familiar desk experience, the Poly CCX 505 offers the mix of usability, audio performance, and deployment flexibility that keeps conversations productive and professional.
