Since 2010, our global team of researchers has been studying Zoom Phone customers around the world, aggregating massive amounts of data points that form the basis of our forecast assumptions and perhaps the rise and fall of certain vendors and their products on a quarterly basis.
Each quarter our research team identifies companies that have purchased Zoom Phone for PBX, VoiP and Phone Systems from public (Press Releases, Customer References, Testimonials, Case Studies and Success Stories) and proprietary sources, including the customer size, industry, location, implementation status, partner involvement, LOB Key Stakeholders and related IT decision-makers contact details.
Companies using Zoom Phone for PBX, VoiP and Phone Systems include: University of Illinois Chicago, a United States based Education organisation with 12000 employees and revenues of $4.18 billion, West Virginia University, a United States based Education organisation with 3224 employees and revenues of $782.0 million and many others.
Contact us if you need a completed and verified list of companies using Zoom Phone, including the breakdown by industry (21 Verticals), Geography (Region, Country, State, City), Company Size (Revenue, Employees, Asset) and related IT Decision Makers, Key Stakeholders, business and technology executives responsible for the software purchases.
The Zoom Phone customer wins are being incorporated in our Enterprise Applications Buyer Insight and Technographics Customer Database which has over 100 data fields that detail company usage of software systems and their digital transformation initiatives.

University of Illinois Chicago | Education | 12000 | $4.2B | United States | Zoom Video Communications | Zoom Phone | PBX, VoiP and Phone Systems | 2025 | n/a |
In 2025 University of Illinois Chicago began transitioning to Zoom Phone within its PBX, VoiP and Phone Systems environment. The university telephone service is being upgraded to a cloud-based voice platform that combines traditional telephone service with the Zoom meetings platform, and this change explicitly does not impact phone service provided in UIHealth. Technology Solutions maintains a bi-weekly Zoom Phone Transition community update to communicate schedule, procurement guidance, and rollout status to staff and faculty.
Zoom Phone deployment is structured as a cloud voice overlay integrated with the existing Zoom meetings tenancy, enabling standard PBX capabilities such as desk phone provisioning, softphone clients on desktop and mobile, and PSTN calling as part of the unified communications workflow. Technology Solutions tested and curated recommended handset models to support predictable provisioning and user experience, including 405HD IP Phone, Poly Edge E100 and E220, and Yealink SIP-T46U. The implementation emphasized easy provisioning workflows so units that require physical desk phones see a familiar look and feel while most users continue to use the Zoom app.
Procurement and device power are governed at the departmental level, departments and units are responsible for purchasing physical handsets and headsets through approved university vendors, and Technology Solutions publishes the recommended models and ordering path on the CDW-G Technology Solutions portal at cdwg.com/techsolutions. Many campus network ports support Power over Ethernet PoE so recommended handset models often do not include power adapters, however if a location lacks PoE a compatible power adapter should be ordered to avoid setup delays. The rollout scope targets staff and faculty across units that opt for handsets, with Technology Solutions providing device testing, provisioning standards, and ordering guidance.
Governance for the Zoom Phone implementation is centered on the curated device list, departmental procurement responsibility, and a communication cadence driven by the Zoom Phone Transition community updates. The project narrative highlights a sustainability objective by encouraging softphone adoption and PoE powered devices to reduce waste and streamline communication, while Technology Solutions retains responsibility for handset validation and provisioning standards.

West Virginia University | Education | 3224 | $782M | United States | Zoom Video Communications | Zoom Phone | PBX, VoiP and Phone Systems | 2025 | n/a |
West Virginia University selected and began deploying Zoom Phone in 2025 as its new PBX, VoIP and Phone Systems application to replace legacy on‑premises Cisco hardware. Deployment is structured as a staged, university‑led migration: units have been migrating since January with a visible campus milestone on August 15, 2025, and ITS managing a two‑year transition that is expected to complete by July 1, 2026. ITS is working with identified unit points of contact who coordinate migrations and units receive a 30‑day notice ahead of their scheduled cutover.
The implementation uses Zoom Phone as a cloud‑based, full‑service calling solution and is integrated with WVU Microsoft 365 services to provide a near‑seamless experience for users familiar with Teams. Approximately 30 administrative and academic units have transitioned so far, along with the Beckley and Keyser campuses and Jackson’s Mill; decisions about which phone numbers to retain were made at the college or department level. The rollout eliminates reliance on on‑premises telephony hardware, though departments may optionally purchase physical phones (phone purchases do not include associated line charges). Telecommunications rates have been frozen until the migration completes.
ITS expects operational benefits explicitly stated in project materials: by moving to the cloud, WVU will avoid deferred maintenance costs exceeding $1 million and provide a calling platform better suited to a large, hybrid and remote workforce.
