Here’s a detailed breakdown of how these virtual phone services stack up, ranked from highest to lowest based on their price, functionality, and integrations.

1. Quo: The best business phone number app for growing teams

Pros

• Unlimited calls and texts to the US and Canada
• Local and toll-free virtual numbers are available
• Available on iOS, Android, desktop, and the web
• Internal threads, contact notes, and call recordings for team coordination
• IVR auto-attendant for inbound calls

Cons

• Can’t verify accounts through two-factor authentication*

*Nearly all virtual phone numbers share this problem. For safety reasons, companies like Facebook, Uber, and Google rarely let you authenticate accounts through a virtual phone number.

Quo, formerly OpenPhone, is a collaborative VoIP system that scales with your business. Since Quo operates over an internet connection, you can manage all your business calls and texts on any existing computer, smartphone, or tablet. There’s no need to invest in a desk phone or expensive hardware. Plus, every plan includes the essentials like call recording and voicemail transcripts.

Quo helps your team collaborate with shared numbers, simultaneous ring, contact notes, and internal threads. With these features, your customers won’t wait long on hold or have to repeat themselves when they reach a new rep. Any of your customer service representatives can read notes from previous calls and get up to speed.

You can also expedite your team’s next steps and action items by using Quo’s AI transcriptions, call summaries, and suggested message responses. We also let you connect your favorite tools like Slack, Salesforce, HubSpot, Jobber, Make, and Zapier with our integrations.

Quo is the best business phone number app for small businesses and growing teams, but you don’t have to take our word for it. Try Quo with our seven-day free trial.

Key features of Quo

2. Google Voice: Best  business phone app for Google Workspace users

Pros

• Make free calls to the US
• Integrates with other Google Workspace apps

Cons

• Texting is available in the US only
• Costs more than other business phone system providers
• No integrations outside Google Workspace

If you’ve ever Googled ‘VoIP,’ you’ve no doubt run into Google Voice. This is one of the most popular business solutions on the market.

Google Voice integrates with Google Workspace apps, making it a popular draw for businesses that already use Gmail, Google Sheets, and Google Docs.

Keep in mind, though, it doesn’t offer toll-free numbers, auto-replies, or differentiation between personal phone calls and your second number.

During testing, we also noticed every voicemail message, text, or call is organized in separate inboxes. This made it harder to get overviews of conversations with customers and respond quickly.

Key features of Google Voice

• Free unlimited calling to the US from anywhere and to Canada from the US
• SMS in the US
• Mobile phone and web apps
• Google Calendar and Google Meet integrations
• Auto-attendant and ring groups with upgrade

Google Voice pricing

Google Voice’s pricing plans give you four options to choose from:

• Starter with Voice only: $10 per user per month for one user, free calls in the US and Canada, access to mobile and web apps, and voicemail transcriptions
• Starter with Workspace: $10 per user per month for up to 10 users, free calls in the US and Canada, access to mobile and web apps, and voicemail transcriptions
• Standard: $20 per user per month to unlock unlimited users, on-demand call recordings, ring groups, and phone menus
• Premier: $30 per user per month to unlock automatic call recordings and advanced reporting

An additional $7 per user per month for Google Workspace is required to use Google Voice for business, except on the individual Starter plan.

3. Grasshopper:  Best business phone number app with multi-digit extensions

Pros

• Unlimited calling to the US and Canada
• Auto-attendant phone menu with extensions

Cons

• $500 deposit to make international calls
• No shared phone numbers
• No Slack, Zapier, or CRM integrations

Grasshopper is one of the oldest virtual business phone number apps with unlimited calling in the US and Canada. One of its standout features is single-digit extensions for departments and multi-digit extensions for employees.

Compared to other providers in this article, their platform is relatively bare-bones with basic features like voicemail greetings and transcriptions. Even when they go the extra mile and offer auto-replies, they can only go out to first-time callers.

You have to upgrade your plan to get access to auto-attendant, call recording, and call transfers.

During testing, we noticed that the process to set up an auto-attendant was clunky. To many business owners, the platform will feel dated.

Key features of Grasshopper

• Unlimited calls to Canada and the 48 continental states
• Android and iOS mobile apps
• Vanity numbers
• Call transfers with upgrade
• Voicemail to text

Grasshopper pricing

Grasshopper’s pricing offers three plans. Here’s what you can expect to get with each:

• True Solo: $14 per month for one user, one phone number, and one extension
• Solo Plus: $25 per month for unlimited users, one phone number, three extensions, auto-attendant, simultaneous call handling, call transfers, and call recording
• Small Business: $55 per month for unlimited users, four phone numbers, unlimited extensions, and everything in Solo Plus

4. Nextiva: Best business phone app for teams using Microsoft

Pros

• Unlimited calling within the US and Canada
• Video calling features
• Microsoft Outlook integration comes standard

Cons

• Toll-free numbers and minutes require an upgrade
• Microsoft Teams integration requires an upgrade
• Usage-based call transcripts and summaries

Nextiva launched in 2006 as a basic business phone number app. Today, it brands itself as a customer experience company, with options to add channels like live chat, social media, and email. 

Companies using Microsoft products can connect Nextiva to Outlook on the base plan, but will need to purchase an add-on or upgrade for the Teams integration. Unlike with other providers, reps can only send 100 texts each per month unless you upgrade. For cost reasons alone, many small businesses seek out Nextiva alternatives.

Key features of Nextiva

• Virtual fax services with add-on or upgrade
• Integration with Google Contacts comes standard
• Unlimited voice and video conference calling 
• Voicemail transcriptions 
• Toll-free number support with upgrade

Nextiva pricing

Nextiva’s pricing offers three plans to its customers:

• Core: $15 per user per month for inbound and outbound voice, limited business SMS, video meetings, and call routing
• Engage: $25 per user per month for customer-to-team SMS messaging, toll-free number and minutes, advanced reporting, and MS Teams integration
• Power Suite CX: $75 per user per month for inbound sales and service call center, priority and skills-based routing, unified team interface, and supervisor dashboard

5. Zoom Phone: Best business phone app for video integration

Pros

• Offers calling, texting, and video conferencing
• Integrates seamlessly with Zoom Workplace, Scheduler, Rooms, and Events & Webinars
• Desk-phone compatible

Cons

• Outbound calling requires an upgrade
• Additional cloud storage costs extra
• Limited integrations

If your small business already uses Zoom to meet with clients, Zoom Phone can be a viable VoIP option. In-call controls let you switch to a video meeting, transfer calls, and record calls — all without leaving the interface. As your business grows, you can also host large webinars and use Zoom to schedule appointments. 

The downside with Zoom Phone is that it can get expensive for small teams. Outbound calling is only available on higher-tier plans, and useful AI features like team SMS summaries require an upgrade. Past users have also reported issues with international calling restrictions and a clunky interface. 

Key features of Zoom Phone

• Metered international calling
• AI call summaries with upgrade
• Shared phone numbers for calling
• Voicemail transcription
• Call transfers

Zoom Phone pricing

You can choose from five different Zoom Phone pricing plans:

• Pro Plus: $18.32 per user per month for access to Zoom Workplace Pro plus everything in the Unlimited plan
• Global Select: $20 per user per month for unlimited calling in 40+ countries, a direct dial number, and everything in US & Canada Unlimited
• Business Plus: $22.49 per user per month for access to Zoom Workspace Business, visitor management tools, real-time reporting dashboards, and access to international calling add-ons

6. Dialpad: Best business phone number app for AI call monitoring features

Pros

• Real-time AI-powered call coaching on higher plans
• Unlimited calling to the US and Canada
• Shared phone numbers

Cons

• No international texting on the base plan
• Auto-replies require an upgrade
• Additional numbers require an upgrade

What makes Dialpad unique is its AI call coaching and call sentiment tracking. It can tell you when your team members are speaking too fast or slow, and let team leaders correct reps on live calls. However, these features are only available on Dialpad Support and Sales plans. 

On Dialpad’s business phone plan, the features are fairly standard: shared numbers, multi-level auto-attendant, and call recording are included. If you want more than one phone number, to text internationally, and integrations beyond Google Workspace, you’ll have to upgrade.

During testing, we found the admin settings to be time-consuming and clunky to set up.

Key features of Dialpad

• AI-powered call transcriptions and summaries
• Fax, SMS, and MMS available for US and Canadian customers only
• Unlimited video meetings
• Salesforce, MS Teams, ServiceNow, Zendesk, and more integrations with upgrade

Here are the options:

• Standard: $15 per user per month for AI-powered call and voicemail transcriptions, Dialpad SMS, and Google Workspace integrations
• Pro: $25 per user per month for the option to have additional numbers, international texting, auto-replies, and CRM integrations with a required minimum of three users
• Enterprise: Call for a quote and get 100% uptime, unlimited locations and ring groups, SSO integrations, and live agent support with a required minimum of 100 users

Pros

• Desk phone support

Cons

• Call recordings automatically deleted after 90 days
• Base plan only includes 25 texts per user per month
• Limited toll-free minutes

RingCentral is a legacy business communications platform that was founded in 1999. It supports desk phones, which is handy if your business still uses them.

But RingCentral isn’t without its drawbacks. For example, you’ll need to pay a one-time setup fee of $30 for vanity phone numbers. Plus, you only get more than 100 pooled toll-free minutes per month if you upgrade. Text messaging is also capped at 25 messages per user per month, which might not be enough for your business.

Key features of RingCentral

• IVR
• SMS and MMS support
• Shared voicemail
• Voicemail transcripts
• Unlimited calls in the US and Canada
• Shared numbers

RingCentral pricing

RingCentral’s pricing plans give you three different options to choose from:

8. Ooma Office: Best business phone for teams that need fax and paging support

Pros

• Unlimited calling in the US, Canada, Mexico, and Puerto Rico
• Texting in the US and Canada
• Compatible with desk phones

Cons

• Limited toll-free minutes

Ooma is a business phone number app with useful features for teams that still work in a physical location. You can access virtual faxing, overhead paging, intercom calling, and connect to desk phones. If you have a hybrid team, you can also use features like CRM integrations, calling on the desktop app, and videoconferencing — but only on higher plans. 

Unlike other providers on this list, Ooma doesn’t have unlimited texting. After you upgrade to access it, you’ll still only have 250 free messages per user per month. Users have also reported reliability issues like messages not being received and calls not being forwarded. Unless you need in-office legacy features, you may want to find an Ooma alternative. 

Key features of Ooma

• Simultaneous ring 
• Mobile and desktop apps
• Video conferencing 
• Team chat with upgrade

Ooma pricing

There are three different pricing plans for Ooma.

• Essentials: $19.95 per user per month for auto-attendants, call forwarding, and overhead paging support

How we ranked the best business phone number apps

We personally tested each app since we know how frustrating dropped calls, hidden fees, and dated software can be as a growing business. We determined the top options after reviewing the following key factors across each app:

• Reliability: Does it work when you need it to? Call drops and system outages aren’t just inconvenient  — they can cost you customers. In fact, research shows 68% of customers will move to a competitor after poor business communication. We prioritized apps with clear call quality and stable connection for this list. 
• Business value: What problems does it solve? What value does the app generate for your business? The cheapest option is usually not the best app. You need a system that saves your team time and has predictable monthly costs. For example, we prioritized apps with shared phone lines, call transcripts, and other features that help businesses work more efficiently. 
• Integration capabilities: Does it connect to your existing workflow? Speaking of saving time, integrations can help your team cut repetitive tasks from their daily responsibilities. We looked for apps with popular CRM and other integrations that automatically log calls, sync data, and eliminate time-consuming manual data entry. These become especially important as your business grows. 
• Ease of setup: How hard is it for your team to get started? Customizing your phone settings and getting team members up and running shouldn’t take hours. The best business number apps have intuitive interfaces that aren’t taxing to operate if you’ve ever used a smartphone. We didn’t include apps that require an IT person and weeks to set up. 
• Support quality: Do they help when things go wrong? If questions come up and you don’t see your question addressed in the Help Center, you need a responsive customer support team. We looked for business phone systems that offer reliable, fast support through different channels like phone and live chat. 
• Pricing: Are there hidden fees? We looked beyond the pricing page to find the actual costs for each provider. That way, you know how much to budget for before getting locked into a contract.

How to choose a business phone number app by company size

If you’re ready to move beyond using a personal number for business, you need an app to keep things professional. But how can you choose which one is right for you without overpaying? Here’s a quick breakdown:

For solo entrepreneurs

If you’re a team of one, look for an app that gives you a second phone number on your existing cell phone. You’ll also want basic features like voicemail transcription and customizable business hours. At this stage, you don’t need team features‌ — just professional call handling without extra hardware.

Keep in mind: While many people choose low-cost providers like Google Voice at this stage, you may run into issues if you ever plan to add team members.

For small teams of 2-10 people

As a growing team, you need an app with shared inboxes so your team can see all calls and texts to a number, leave internal notes, and assign follow-ups. This stops things from falling through the cracks, which helps you prevent a poor customer experience.

What works well: Quo’s Starter plan is a great way to get shared inboxes and other key features like auto-replies at an affordable price. You’ll also have the option to easily add numbers, users, and features once you’re ready to upgrade.

For fast-growing companies of 10+ people

At this stage, you should look for a system that can grow with you. Prioritize features like IVR phone menus to route calls to the right department, CRM integrations, and analytics to see how your team is performing.

At this scale: Providers like Nextiva, RingCentral, and Quo all offer these advanced features, but differ in their approach. Consider whether you need traditional call center tools like call monitoring and skills-based routing, or collaboration features like internal threads and AI call summaries.

Which features do you actually need? Skip the bloat

Here’s a quick breakdown of features you’ll likely need based on your team size: 

Feature	Solo	Small team	Growing company	Why it matters
