The Best VoIP for Small Businesses in 2026

When it comes to small business VoIP services, RingCentral is always an industry leader. What sets it apart is its robust call management system, which streamlines inbound and outbound calls with exceptional efficiency. Even with its base plan, you receive a range of essential features for effective call distribution. 

It also secured a spot on our list of the best business cell phone plans due to its essential call features, including call forwarding, call transfer, and answering rules. But if you find RingCentral’s features and integrations a little overwhelming for your needs, consider a straightforward alternative like Ooma. This provider prioritizes call quality and ease of use, making it an ideal choice for businesses seeking simplicity.

• Multilevel IVR: Set up routing menus with a visual IVR editor and route calls to voicemail, extensions, and external phone numbers. Each account supports up to 250 voice menus and submenus.
• Multisite management: Support the unique needs of all of your branch offices within a single account. Each site has its own outbound caller ID, call handling rules, user roles, and auto-receptionist.
• AI assistant: Paired with call recording, the AI features provide transcriptions, summaries, and notes, offering virtual assistance and feedback during business calls.

When it comes to customer experience (CX), Nextiva is my go-to choice. If you've had the chance to attend a Nextiva event, you know the company offers deep insights and reports that show how to elevate VoIP phone systems into a powerful multichannel customer experience platform. Nextiva also stays on the cutting edge of digital technology, offering access to an AI receptionist and agentic tools.

But even with its wide array of features, Nextiva limits SMS messaging credits on its small-business plans. If business messaging is key to your customer experience, then consider Grasshopper. It's one of our top picks for cheap VoIP services due to its unlimited business messaging across plans.

• Call pop: This feature displays the caller’s details before you pick up the call. Customize it to display whatever customer information you need, such as sentiment or account value.
• Automation tools: Enhance service efficiency with features such as automated surveys, real-time suggestions, and automated follow-ups.
• Call flip: This feature transfers an ongoing call between devices without interruption. This feature works on desk phones, computers, and mobile phones.

Before audio conferencing became the staple of remote work, Zoom was already making waves as a pioneer in video conferencing technology. But here’s something you might not know. Beyond its popular Workspace plans, Zoom Phone offers a range of calling options specifically designed for small business owners, featuring both metered and unmetered plans at affordable prices.

Unfortunately, Zoom Phone does not provide vanity numbers for businesses seeking to create a memorable impression with their customers. A great alternative is Grasshopper, our top virtual phone system provider, which offers toll-free number bundles and vanity numbers at no extra cost.

• Call quality dashboards: View overall call quality and filter voice data for a specific user. It includes usage reports that display phone usage data for a specific user or call queue.
• Shared line groups: Share a phone number and extension with common-area phones or with a group of phone users. You can set routing rules and apply custom business hours.
• Call delegation: Assign a phone user to make and receive calls on behalf of another user. Both users can view the status of the shared lines and access the delegator’s direct phone numbers.

Starting a new business comes with its own set of challenges, and selecting the right phone plan can feel overwhelming, especially when you’re unsure about call volumes or your clients' needs. That’s exactly why I chose Phone.com as one of the top choices for a VoIP phone system. Phone.com offers flexible plans that are tailored for small businesses with low or seasonal call volumes.

At the same time, Phone.com has relatively few integrations, limiting its ability to connect with third-party apps. If you're looking for a VoIP solution that seamlessly integrates with your existing app stack, consider RingCentral. It features a dedicated app gallery with over 300 business solutions for automation, CRM, and productivity.

• Call handling: Create rules to route incoming callers to the right destination. Options include forwarding, auto-attendant, dial-by-name directory, and scheduled routing.
• Live receptionist: Add live answering services to your Phone.com account to access professional phone operators to answer your business calls.
• Voice tagging: This feature announces which menu option the caller selected before the call is answered. It is helpful for businesses with multiple auto-attendant options that ring to the same number.

Gone are the days when an international phone call could significantly impact your budget, making it challenging for businesses to tap into global markets. With GoTo Connect, you can enjoy unlimited calls to over 50 countries for a single monthly subscription. Unlike other providers, which limit access to business phone numbers, GoTo Connect offers toll-free and vanity phone numbers tailored to your business needs.

Additionally, it provides number porting services, helping you save time and money when transferring an existing phone number. But, as much as I enjoy GoTo Connect’s AI features and unified communications system, it still cannot outperform RingCentral, which excels with its powerful analytics, popular integrations, and superior call handling, making it my recommendation for growing businesses.

• Custom auto-attendants: Record unlimited customized messages and voicemail greetings with the GoTo Connect desktop or web app. Use it to share important updates and keep callers engaged while they wait in a queue.
• Team messaging: GoTo Connect enables you to send files and messages to team members, facilitating communication and collaboration on projects.
• Customized call flows: The drag-and-drop interface is an intuitive admin tool that enables you to edit, update, and modify call flows. It also allows you to set up multiple auto-attendants and track how calls are routed to extensions or departments.

Among all the providers on this list, Grasshopper stands out as a top choice for small business owners. Specifically, Grasshopper has always stood out to me for its dedication to creating business phone plans designed for solopreneurs. To further enhance a business's professional image, Grasshopper offers toll-free vanity numbers at no cost, solidifying its reputation as one of the best free VoIP services.

While most VoIP providers charge a one-time setup fee for vanity numbers in addition to the monthly rate, Grasshopper allows you to choose a local or toll-free vanity number when you subscribe to a monthly plan. However, Grasshopper lacks features like video meetings and team chat. For businesses that require these tools for effective team collaboration, Nextiva is a better choice due to its comprehensive unified communications features.

• Call control: Grasshopper lets you screen incoming calls by blocking callers and setting custom schedules based on your business hours. 
• Virtual receptionist service: Adding Ruby to your Grasshopper account gives you a professional phone answering service that will handle calls on behalf of your business. 
• Custom greetings: You can record phone greetings or have a professional voice actor record your script in Grasshopper’s voice studio.

While some business owners thrive on a comprehensive suite of features, others simply need a dependable service that delivers exceptional call quality. That’s why I chose Ooma. The platform emphasizes essential functions, including call forwarding, voicemail, automated routing, hold music, and ring groups. Although it has limited collaboration tools and integration options, it is ideal for smaller teams looking to manage call traffic through an app.

Additionally, this platform earned a spot on our list of the best VoIP services for home offices, primarily for its free home phone service. But even with its video conferencing capabilities, Ooma’s collaboration tools are not as advanced as those provided by other VoIP services. For a more robust solution, I recommend Zoom Phone, which offers all the benefits of a business phone system and access to a suite of unified communication tools.

• Multidevice ring: This call forwarding type allows you to receive calls on any device and enables multiple devices to ring simultaneously when an Ooma user is called.
• Extension monitoring: This feature enables a user or receptionist to monitor the status of other phone extensions and perform various actions, such as call transfer or three-way calling.
• Distinctive ringtones: Add a unique ringtone to a call queue or ring group to notify team members about the nature of the incoming call.

Aircall stands out for connecting business calls with the tools sales and customer support teams use every day. Its more than 250 integrations include HubSpot, Salesforce, Zendesk, Shopify, and Microsoft Teams. These connections can automatically log calls and customer details, giving employees more context without requiring them to switch repeatedly between their phone system, CRM, and help desk.

I also like Aircall’s balance of straightforward setup and advanced call management. However, Aircall is not the best fit for solopreneurs or teams looking for the least expensive VoIP service. Both standard plans require at least three licenses, resulting in a minimum monthly commitment of $90 with annual billing. Businesses that need an affordable service for one or two users should consider Zoom Phone instead.

• AI Assist: Generate call summaries, action items, sentiment insights, topic recognition, call scores, CRM updates, and follow-up emails. Standard AI Assist is included with Professional, while more advanced live coaching tools require AI Assist Pro.
• Advanced call routing: Build IVR menus and distribute incoming calls based on business hours, teams, availability, or routing rules. Professional adds smart routing and manual or automated queue callbacks.
• Sales productivity tools: Professional subscribers receive a power dialer, voicemail drop, mandatory call tagging, and advanced analytics for monitoring outbound sales activity.
