Our verdict

This Zoom review is about Zoom Phone, the business phone system that sits inside the same app millions of teams already open every day for meetings. That is its whole argument: one app for calls, meetings and chat, one bill and one admin portal. Zoom Phone gives each user a real phone number with unlimited or metered calling in the US and Canada, business texting, online fax, call recording and AI that summarises calls and pulls out follow-up tasks. Bundled plans add the full paid Zoom Workplace meeting experience on top.

It is the natural pick when video is the centre of how your team works and the phone line is the thing you are adding. The trade-offs are the meeting limits on the entry bundle, some analytics and contact centre features sold separately, and an admin console with a lot of settings to learn. If the phone system is the centre of your business and video is incidental, a phone-first platform may give you more depth for the same money.

NerdBible did not run a hands-on trial for this review. It is an editorial assessment based on Zoom's own product, security and AI pages and on the published findings of independent outlets, which we credit and link below.

What is Zoom Phone and who is it for?

Zoom Phone is a cloud VoIP phone system from Zoom Communications. According to the Zoom Phone product page, it runs in the Zoom desktop and mobile apps, on the web and on supported desk phones, and works together with Zoom Meetings and Zoom Chat in the Zoom Workplace platform. A call can be turned into a video meeting without everyone hanging up and rejoining.

It suits:

  • Teams that already use Zoom for meetings and want calling in the same app, with one set of users to manage.
  • Hybrid and remote workers who move between desk, laptop and phone during the day.
  • Businesses with international offices, since Zoom offers local calling in many countries and lets companies bring their own carrier.
  • Light callers, because the metered option suits staff who mainly need to be reachable rather than make many outbound calls.

It is not a residential service. Households looking for a home landline replacement should look at a home VoIP provider instead.

Key features

Calling and call handling

Zoom lists the features you would expect from a full business phone system: auto attendants and call routing, call queues, shared lines, call transfer, one-touch calling to a teammate or group, call recording, voicemail, and the ability to move a live call between devices. Domestic SMS and MMS and online fax are included on the phone plans. Admins assign numbers, set calling permissions and update policies in one portal. Zoom says the service has global PSTN coverage in more than 49 countries, supports bring your own carrier (BYOC) for other locations, and offers E911 support and a Local Survivability option that keeps calling working if a site loses its connection to the cloud.

AI features

The phone plans include AI post-call summaries, voicemail prioritisation and task extraction. Zoom's AI assistant, now called ZoomMate on its AI assistant page, can also summarise team SMS threads, answer questions during a conversation and pull together follow-ups across meetings, chat and calls. Zoom also offers an AI virtual receptionist that greets callers, answers common questions, books appointments and routes calls. Some of the more advanced AI tools depend on which Workplace plan you hold.

Meetings and chat

Every Zoom Phone bundle includes Zoom Meetings and team chat. On the entry bundle, meetings follow the basic Workplace limits of 40 minutes and 100 participants. The Pro Plus bundle extends meetings to 30 hours and adds unlimited AI note-taking, while Business Plus raises the participant limit to 300 and adds admin and compliance tools.

Integrations and hardware

Zoom lists integrations with Salesforce, HubSpot, Microsoft Teams, Slack and Google, and lets businesses embed Zoom Phone in their own applications. Teams users can make Zoom Phone calls directly from Microsoft Teams. Desk phones from major brands are supported, or staff can use their own devices.

How much does Zoom Phone cost? Plan structure explained

Our page shows current prices from our data, so here is how the plans fit together rather than the figures. Zoom sells Zoom Phone in two ways.

  • Phone-only plans. PCMag and TechRepublic describe a metered US and Canada plan where outbound calls are charged per minute, a regional unlimited plan for the US and Canada, and Global Select plans that give unlimited domestic calling in one of dozens of other countries. An add-on covers unlimited calling to a list of international destinations.
  • Bundles with Zoom Workplace. Zoom's product page lists US and CA Unlimited calling added to Workplace Basic, Pro Plus (calling plus Workplace Pro) and Business Plus (calling plus Workplace Business). The higher bundles unlock longer and larger meetings, more AI and more admin controls.

Plans can be billed monthly or annually, with a lower effective rate on annual billing. Zoom's product page currently says its free trial is only available to existing Zoom Phone customers, so new buyers should plan on a demo or a small pilot instead. Add-ons such as the Customer Engagement Pack, which adds live queue data, cost extra, and PCMag notes that detailed call queue analytics require a paid Power Pack add-on.

Is Zoom Phone safe and secure?

Zoom's Trust Center describes encryption, multi-factor authentication and data protection measures, and links to its library of security certifications and attestations. For phone calls specifically, Zoom's end-to-end encryption announcement explains an option to upgrade a one-to-one call to end-to-end encryption. The conditions are strict: both people must be on the same Zoom account, both must use the Zoom app rather than a regular phone line, an admin must turn the feature on, and automatic call recording must be off. Calls to and from ordinary phone numbers are not end-to-end encrypted, which is true of every business phone system that connects to the public telephone network.

Zoom also describes 99.999% uptime on its product page, along with failover options. business.com notes HIPAA-compliant options for healthcare and other regulated businesses on eligible plans. Organisations with strict requirements should ask Zoom for the specific attestations that cover their plan.

Setup and support

Basic setup is straightforward: assign a licence and a number to each user and they can start calling. Zoom says businesses can transfer existing compatible numbers and can book up to three one-hour training sessions with a Zoom Phone expert. Independent reviewers split on the admin side. PCMag found it clear and simple, with features like barging and call queues behind a single toggle, while business.com found the number of configuration options overwhelming at first. Support also varies by plan, as covered below.

What could be better

  • Short meetings on the entry bundle. The basic Workplace allowance caps meetings at 40 minutes, so meeting-heavy teams need a higher bundle.
  • Analytics cost extra. PCMag found the built-in reporting basic and the deeper call queue analytics locked behind a paid add-on.
  • Contact centre is separate. Advanced routing for a dedicated support team is a separate Zoom Contact Center product.
  • A busy admin console. Small businesses moving from a landline may need time to learn the settings.
  • Support depends on plan. Some outlets report slower help on lower tiers.
  • No open trial for new customers. Zoom's page currently limits the free trial to existing phone customers.

Who should choose something else?

A business whose calls are the product, such as a busy sales floor or support desk, may get more from a phone-first platform with live coaching and deeper analytics, or from a dedicated contact centre. Very small offices that want the simplest possible phone system, preconfigured desk phones and no settings to learn may prefer a simpler provider. Teams that already standardise on Microsoft Teams or Google Workspace for meetings might find a phone add-on for those platforms easier than bringing in Zoom. And if your staff make only occasional calls and already have a meetings tool, the metered plan or a basic number forwarding service may be all you need.

Is Zoom Phone worth it?

For teams that already live in Zoom, yes. Putting calls, texts, fax, chat and meetings in one familiar app, with AI summaries and task extraction included, removes a lot of friction and a separate vendor. The metered option makes it unusually cheap to give everyone a number, and international businesses benefit from Global Select and BYOC. Just budget for the bundle that matches how long and how large your meetings are, and check which analytics and contact centre features need add-ons.

What other reviewers found

  • PCMag gave Zoom Phone its Editors' Choice award, praising call quality, reliable AI summaries and strong telephony features at a low price, while noting that detailed call analytics need a paid add-on.
  • TechRepublic focused on the metered plan, finding it good value for staff who make few outbound calls, and highlighted bring-your-own-carrier support and the Salesforce integration on the base plan.
  • Tech.co scored Zoom Phone well for call management and security but criticised its small selection of CRM and help desk integrations, basic reporting and limited support on lower plans.
  • business.com chose it as the best business phone system for video conferencing, liked the AI follow-up tools, and found the admin settings more demanding than simpler rivals.

Where the outlets agree and disagree

The outlets agree that Zoom Phone's biggest strength is the tight link with Zoom's meeting platform, that call quality is good, and that it is an affordable way to give a team business numbers. They also agree that reporting and analytics are basic unless you pay more.

They disagree on integrations and support. PCMag counted around 160 integrations and found chat support fast, while Tech.co counted only a handful of CRM and help desk connections and rated support poorly, and business.com called the native integration lineup more limited than some rivals'. The difference is partly definitional: Zoom's wider app marketplace is large, but phone-specific CRM integrations are fewer. Tech.co also says Zoom Phone lacks online fax, while Zoom's current plan table lists domestic online fax on every bundle, so that point appears to be out of date.

For a buyer, the message is to list the two or three apps your team cannot work without and confirm that each one connects to Zoom Phone specifically, not just to Zoom Meetings, before committing.

Frequently asked questions

Is Zoom Phone a good business phone system?

For teams that already use Zoom, it is one of the most convenient choices. It offers unlimited or metered calling in the US and Canada, business texting, online fax, call recording and AI call summaries in the same app as Zoom Meetings and Chat. PCMag gave it an Editors' Choice award. Its weaker areas are reporting, which needs paid add-ons for depth, and contact centre features, which are a separate product.

Do I need a Zoom Workplace plan to use Zoom Phone?

No. Zoom sells phone-only plans as well as bundles that combine Zoom Phone with a Zoom Workplace plan. Phone-only users still get basic Zoom Meetings and chat. The bundles make sense when you also want longer or larger meetings, unlimited AI note-taking, more whiteboards and stronger admin tools. Pick the option that matches how much of your day is spent in video meetings.

Are Zoom Phone calls encrypted?

Zoom says it uses encryption and other security measures across its platform. One-to-one Zoom Phone calls between people on the same Zoom account, using the Zoom app, can be upgraded to end-to-end encryption once an admin enables it and automatic recording is off. Calls that reach ordinary phone numbers cannot be end-to-end encrypted, which applies to any business phone service connected to the public network.

Can Zoom Phone replace a desk phone system?

Yes. Zoom Phone supports desk phones from major manufacturers, as well as desktop and mobile apps, so you can keep handsets on desks or move to software only. Zoom lets businesses transfer existing compatible numbers, set up auto attendants and call queues, and offers E911 support and a Local Survivability option for sites that lose their connection to the cloud. Check that your current handsets are on Zoom's supported list.

Does Zoom Phone work outside the US?

Yes. Zoom says its phone service has PSTN coverage in more than 49 countries, and Global Select plans give unlimited domestic calling in a chosen country. Businesses in unsupported locations can bring their own carrier and still use Zoom Phone as the calling platform. International calls outside your plan are charged per minute, and an add-on covers unlimited calling to a list of destinations.
