Product Overview

The Poly CCX 505 Microsoft Teams phone is a mid-range business media desk phone that runs native Microsoft Teams firmware on a 5-inch color touchscreen, with a dedicated Teams button for one-press access to the Teams home screen. This SKU (82Z79AA) is the PoE-enabled model: it draws power over the same Class 0 Ethernet drop that carries voice traffic, so a standard desk deployment needs one cable and no local outlet. Integrated Wi-Fi and Bluetooth make it practical for hard-to-cable desk arrangements, hot-desking pods, and home-office extensions of a corporate Teams tenant. For IT teams standardizing knowledge-worker desks on Teams Phone, it replaces a legacy SIP handset with a certified endpoint that provisions and updates from the same management stack as the rest of the Teams estate.

Product Description

Poly built the CCX 505 for the desk worker who lives in Microsoft Teams and expects the phone to behave like the client. The native Teams experience runs on the phone itself rather than through a SIP gateway, so presence, contacts, calendar, and meeting join all match what the user sees on the desktop. The 5-inch multi-touch LCD runs at 1280 x 720 in a 9:16 layout with dark mode, which keeps contacts and the current call visible without paging through soft-key menus. Because this is the PoE-only part number, the box does not include a power adapter a Class 0 PoE switch port supplies the 13 W the phone needs, and installations without PoE (or those running the phone on Wi-Fi rather than a wired drop) should order a Poly 25W power supply alongside the handset.

Audio is where the CCX line earns its place in an open commercial office. Poly HD Voice and Poly Acoustic Clarity carry the full 100 Hz to 20 kHz band across the handset, speakerphone, and headset paths, while Poly Acoustic Fence suppresses voices originating outside a defined zone around the user and NoiseBlockAI attenuates keyboard clatter and HVAC noise on the speakerphone. Full-duplex speakerphone operation with echo cancellation means a caller is not clipped when both ends talk at once, which matters in call-handling roles far more than raw loudness.

Connectivity is built for a mixed desktop. A USB Type-A and a USB Type-C port sit on the side of the phone for USB headsets, and integrated Bluetooth pairs wireless headsets without a dongle. A dedicated RJ-9 port supports traditional wired headsets, and the phone can act as a USB audio device for a connected PC. Two Gigabit Ethernet ports form an integrated switch so the desktop PC daisy-chains through the phone rather than consuming a second switch port. Reception and operator desks that route heavy call volume can add the Poly CCX EM60 expansion module for additional line keys and busy-lamp fields, and installs that need the phone off the desktop entirely use the Poly CCX 500/505 wall mount bracket. Rooms that outgrow a personal phone are better served by a Poly Trio C60 conference phone on the same Teams tenant.

Key Features

• Native Microsoft Teams Firmware The phone runs the Teams experience directly, so presence, contacts, calendar, and meeting join match the desktop client without a SIP gateway in between.
• Dedicated Teams Button A hardware key returns the user to the Microsoft Teams home screen in one press rather than several menu taps.
• 5-Inch Multi-Touch Touchscreen A 1280 x 720 color LCD with dark mode keeps contacts, calls, and voicemail one tap away.
• Class 0 PoE Powered The phone draws 13 W from a standard PoE switch port, so a desk install needs a single Ethernet run and no local power outlet.
• Integrated Wi-Fi Built-in wireless lets the phone deploy at desks, home offices, and reconfigured floor plans where pulling a new data drop is impractical.
• Poly Acoustic Fence and NoiseBlockAI Both technologies keep neighboring conversations and ambient office noise out of the far end of the call.
• Poly HD Voice and Acoustic Clarity Wideband audio from 100 Hz to 20 kHz with full-duplex echo cancellation preserves inflection on every audio path.
• Bluetooth, USB-A, USB-C and RJ-9 Headset Support Four headset connection options let each user keep the headset they already prefer.
• Two-Port Gigabit Ethernet Switch The desktop PC connects through the phone, so each desk consumes one switch port instead of two.
• Hearing Aid Compatible The handset supports magnetic coupling for accessibility compliance in commercial and public-sector workplaces.

Typical Applications

• Commercial meeting space
• Conference room

Technical Specifications

Frequently Asked Questions

Does this CCX 505 include a power supply?
No. Part number 82Z79AA is the PoE-enabled model and ships without an AC adapter. It draws 13 W from a Class 0 PoE switch port. If a desk has no PoE, or if the phone will run over Wi-Fi instead of a wired drop, order the Poly 25W power supply separately.

Can this phone be reflashed to Open SIP for a non-Teams platform?
This part number ships with native Microsoft Teams firmware and is sold as the Teams SKU. If the deployment runs a third-party SIP PBX or UCaaS platform, specify the Open SIP CCX 505 instead so the correct licensing and firmware arrive with the hardware.

How does the CCX 505 fit into an existing structured cabling plan?
Each phone needs one Ethernet drop to a PoE switch port. The two-port Gigabit switch in the phone lets the desktop PC connect through the phone, so an existing one-drop-per-desk cabling plan does not need to be expanded to support both devices.

What headsets work with this phone?
The CCX 505 supports Bluetooth headsets, USB headsets on either the Type-A or Type-C port, and traditional wired headsets on the dedicated RJ-9 jack. Users can keep existing headset inventory rather than standardizing on a single connector.

Can it be wall mounted in a corridor or reception area?
Yes. The Poly CCX 500/505 wall mount bracket is the supported accessory for taking the phone off the desktop, which is common in lobbies, warehouse aisles, and shared work areas.

How are these provisioned and managed at scale?
Teams-native CCX phones are enrolled and updated through the Microsoft Teams admin center alongside the rest of the Teams device estate, so firmware and configuration policy follow the same change process as other certified endpoints rather than a separate telephony provisioning server.

Can a receptionist get more line keys?
Yes. The Poly CCX EM60 expansion module attaches to the CCX 505 and adds programmable line keys with busy-lamp fields, which turns the phone into a workable attendant station for front-desk and operator positions.

What warranty and support are included?
The phone carries the Poly one-year limited warranty. HP Poly+ service agreements are available separately for extended coverage and advance hardware replacement; contact Creation Networks for the correct coverage tier for your deployment size.
