Poly CCX 350 – Business Media Phone for Microsoft Teams

Product Overview

The Poly CCX 350 Teams phone is a Microsoft Teams native business media phone built around a physical dial pad rather than a touchscreen, which makes it the practical choice for warehouses, manufacturing floors, lobbies and common-area positions where gloved hands and airborne debris rule out glass. It runs the full Microsoft Teams client on Android with a dedicated Teams button, so users get presence, calendar and call history without a companion PC. Poly HD Voice, Acoustic Fence and NoiseBlockAI keep far-end callers out of the ambient noise floor of an active facility. Powered entirely over an 802.3af PoE drop, the CCX 350 needs one cable per position, which simplifies large deployments for IT and facilities teams.

Product Description

This SKU is the Microsoft Teams firmware build of the CCX 350 — HP part number 848Z7AA#AC3, formerly Poly 2200-49690-019 — and it is a PoE-only configuration that ships without a power adapter. That distinction matters at order time: if a position has no PoE switch port or midspan injector behind it, budget for the separate Poly 5V/3A power supply that covers the CCX 350. Because the phone is a Teams device, it is enrolled, updated and monitored from the Microsoft Teams admin center alongside every other Teams endpoint in the tenant, and Poly Lens adds device-level inventory and firmware control for mixed Poly estates.

The 2.8-inch 640 x 480 color LCD carries the Teams interface, while the dial pad, illuminated hold, speakerphone, select and headset keys handle the call itself. Poly designed the keypad surface to resist debris and to tolerate glove-hand use, which is why this model turns up in retail stockrooms, loading docks and plant offices where a capacitive touchscreen fails within a shift. Audio paths cover handset, full-duplex speakerphone and headset, with TIA-920 wideband type 1 compliance and a 150 Hz to 7 kHz response on all three. A dedicated RJ-9 port and USB headset support let integrators standardize on whichever headset the site already uses, and the handset is hearing-aid compatible to ITU-T P.370 and TIA 504A.

Network side, the CCX 350 presents a two-port gigabit Ethernet switch across LAN and PC ports at 10/100/1000Base-TX, supports IPv4 and IPv6, and provisions from FTP, TFTP, HTTP or HTTPS servers for mass rollouts. Media encryption over SRTP, TLS transport, encrypted configuration files and signed software executables cover the security requirements most enterprise and public-sector voice deployments carry. For wall positions in corridors and shop floors, pair the phone with the Poly CCX 350 wall mount bracket. Sites that need a color touchscreen or programmable line keys at the desk instead should compare this against the Poly Edge E350 IP phone.

Key Features

• Native Microsoft Teams Client — Runs the full Teams experience on the phone with a dedicated Teams button, so calls, presence and calendar are available without a connected PC.
• Physical Dial Pad Design — Replaces a touchscreen with a keypad built to resist debris and tolerate glove-hand use in warehouse, retail and manufacturing positions.
• Poly HD Voice with Acoustic Clarity — Delivers wideband audio across handset, speakerphone and headset paths with full-duplex conversation and acoustic echo cancellation.
• Acoustic Fence and NoiseBlockAI — Strip surrounding room noise and off-axis voices out of the transmitted signal so the far end hears the caller, not the facility.
• 802.3af PoE Class 3 Power — Draws up to 13 W from the switch port, so each position needs one cable run and no local outlet.
• Two-Port Gigabit Switch — Passes 10/100/1000Base-TX through to a desktop PC, preserving a single drop per workstation in cabled offices.
• Illuminated Function Keys — Light hold, speakerphone, select and headset so call state is readable at a glance in dim lobbies and plant areas.
• Enterprise Provisioning and Security — Supports FTP, TFTP, HTTP and HTTPS central provisioning with SRTP media encryption, TLS and signed software executables.
• Accessibility Compliance — Hearing-aid compatible handset meeting ITU-T P.370 and TIA 504A, with ADA Section 508 Subpart B 1194.23 conformance.
• Desk or Wall Deployment — Ships with a desk stand and supports the optional CCX 350 wall mount bracket for corridor and common-area installs.

Typical Applications

• Commercial meeting space
• Conference room

Frequently Asked Questions

Does this CCX 350 SKU run Microsoft Teams natively or does it need Open SIP provisioning?
Part number 848Z7AA#AC3 ships with Microsoft Teams firmware and a dedicated Teams button. It signs in as a Teams device and is managed from the Microsoft Teams admin center, so no separate SIP call server or Open SIP configuration is required.

Does the CCX 350 include a power supply?
No. This is a PoE-only configuration and the box contains the console, handset and cord, CAT-5E cable, desk stand and setup sheet. Positions without an 802.3af switch port or midspan injector need the separate Poly 5V/3A power adapter that covers the CCX 350.

How much power does each phone draw from the switch?
The CCX 350 is an auto-sensing IEEE 802.3af Class 3 device rated at 13 W maximum. Size the PoE budget on the access switch against that figure when planning a floor of positions, and remember the phone also passes gigabit Ethernet through to a connected PC.

Why choose a dial pad phone over a touchscreen model in an industrial space?
The CCX 350 uses a debris-resistant keypad rather than a capacitive touchscreen, so it stays usable with gloves and holds up in warehouse, retail stockroom and manufacturing environments where dust and handling would degrade a glass surface.

Can the CCX 350 be wall mounted in a corridor or common area?
Yes. The phone ships with a desk stand, and the optional Poly CCX 350 wall mount bracket handles wall positions in lobbies, corridors and shop floors where no desk surface is available.

How does the phone fit into an existing headset standard?
A dedicated RJ-9 port and USB headset support cover both wired headset families, so sites can keep their current headset SKU rather than re-standardizing. The handset is hearing-aid compatible to ITU-T P.370 and TIA 504A and works with commercially available TTY adapters.

How are firmware and configuration managed across a large deployment?
The phone provisions from FTP, TFTP, HTTP or HTTPS servers with provisioning and call server redundancy, and Teams-specific policy and firmware flow through the Microsoft Teams admin center. Poly Lens adds inventory and device health reporting across mixed Poly estates.

What warranty applies and what support options exist?
The CCX 350 carries a one-year warranty. Poly+ service agreements are available separately for extended coverage and advance hardware replacement; contact Creation Networks for the coverage tier that matches your deployment size.
