HP Poly CCX 400 (849A1AA#AC3) - Key Features & Benefits

• 5" Multi-Touch Android Touchscreen — Smartphone-Style Interface: The 720×1280 pixel gesture-based capacitive LCD with 9:16 aspect ratio and Android 9 delivers an intuitive, app-like experience — contacts and meetings are one tap away. Supports normal and dark mode, adjustable font size, and a multilingual UI covering 17 languages.
• Poly HD Voice + Acoustic Fence + Acoustic Clarity — Three-Layer Audio Quality: Poly HD Voice and Poly Acoustic Clarity deliver TIA-920 wideband audio (150Hz–7kHz), full-duplex conversations, acoustic echo cancellation, and background noise suppression across all audio paths. Poly Acoustic Fence eliminates distracting background noise when using the handset or a wired headset, keeping every conversation clear at the source.
• Open SIP — Compatible with Major SIP Platforms and Hosted Services: The Open SIP edition is interoperable with Asterisk, FreePBX, 3CX, BroadSoft/BroadWorks, Zoom Phone, RingCentral, and other standards-based SIP/IP PBX platforms and hosted VoIP services. Supports 24 SIP line registrations (with pagination), SRTP, TLS, and HTTPS provisioning for secure enterprise deployments. Ships with Open SIP firmware — does not include native Microsoft Teams functionality.
• Dual Gigabit Ethernet — Single Cable Run to Desk: Two 10/100/1000Base-TX Gigabit Ethernet ports (LAN + PC passthrough) let you daisy-chain a desktop computer through the phone — one cable drop serves both devices. IEEE 802.1p/Q VLAN tagging, QoS Layer 3 TOS, LLDP-MED, and IPv4/IPv6 support meet enterprise network requirements.
• PoE Powered — Single-Cable, Zero-Clutter Desk Installation: Built-in IEEE 802.3af Power over Ethernet (Class 3, 13W max) powers the phone directly over the LAN cable — no AC adapter required when connected to a PoE-capable switch or injector. An optional external 5VDC/3A universal AC/DC adapter is available separately for non-PoE environments.

HP Poly CCX 400 (849A1AA#AC3) - Frequently Asked Questions (FAQ)

• Is this compatible with Microsoft Teams or Zoom?
  This is the Open SIP edition (849A1AA#AC3) — it ships with Open SIP firmware and is designed for Asterisk, FreePBX, 3CX, BroadWorks, Zoom Phone, RingCentral, and other standards-based SIP platforms. It does not include native Microsoft Teams functionality. The Teams edition is a separate product (848Z8AA#AC3). Both editions use the same hardware, but the firmware and provisioning differ.
• What is the difference between the CCX 400 and the CCX 500?
  The CCX 400 is the entry-level model — it has one USB Type-A port and no Bluetooth or Wi-Fi. The CCX 500 adds Bluetooth and two USB ports (Type-A + Type-C), and the CCX 505 adds Wi-Fi. Both use the same Gigabit dual-Ethernet platform and 5-inch touchscreen. Choose the CCX 400 for wired-only environments where Bluetooth and Wi-Fi are not required.
• Does this phone include a power adapter, and how is it powered?
  This SKU ships without a power supply. The CCX 400 is powered via IEEE 802.3af PoE (Class 3, 13W max) over the LAN cable — any PoE-capable switch or injector will power it. If your network does not provide PoE, an optional 5VDC @ 3A universal AC/DC adapter is available as a separate purchase.
