Comparing the best VoIP apps for small businesses
RingCentral: Best for advanced integrations and unified communication
Pros
- Includes voice, team messaging, and video meetings in all plans
- Integrates with 500+ third-party apps, including CRM platforms
- Works across mobile, desktop, and web apps
Cons
- Plans are priced higher than those of other competitors
- Limited SMS credits (25–200 per plan)
- Unlimited storage for call recordings only unlocks at the highest plan
My expert opinion
When I reviewed RingCentral, it stood out for delivering a unified communications experience without forcing upgrades for essential features. The Core plan already includes auto-attendants, team messaging, and video meetings, which many competitors lock behind higher tiers. I also found the integration ecosystem especially useful for businesses already using CRM or helpdesk tools.
I recommend RingCentral for growing teams that need scalable communication across multiple locations or departments. However, if your business relies heavily on texting, the strict SMS limits may be a drawback, whereas providers like Grasshopper offer more flexibility in that area.
- Multilevel auto-attendant: Create up to 250 call menus and submenus to efficiently route callers.
- Call delegation: Assign up to 10 assistants per executive to manage incoming calls.
- Hot desking: Let employees log into any device and access their extension and voicemail.

Nextiva: Best for customer experience and team collaboration
Pros
- Combines voice, messaging, and customer interactions in one unified inbox
- Supports Bring Your Own Device (BYOD) for flexible deployment
- Doesn’t charge for number porting
Cons
- Lacks vanity and international numbers
- Does not offer unlimited SMS on most plans
- The feature set may feel overwhelming for small teams
My expert opinion
When I assessed Nextiva, the unified conversation view stood out from other providers on this list. Instead of jumping between tabs for calls, messages, and voicemails, Nextiva organizes everything in a single-threaded interface. I found this especially useful for tracking customer history and delivering more personalized service, particularly for sales and support teams.
Overall, I recommend Nextiva for businesses that prioritize customer experience and need visibility into every interaction. However, smaller teams with basic calling needs may find the platform overly complex and more expensive than necessary. In those cases, a simpler option like Google Voice may be a better fit.
- Threaded conversations: View calls, texts, voicemails, and chats in a single conversation history.
- Unified digital inbox: Manage email, chat, and messaging channels in one interface.
- NextivaONE app: Combines communication and customer experience tools in a single platform.

Zoom Phone: Best for remote teams and global collaboration
Pros
- Offers affordable domestic and international calling plans
- Native mobile and desktop apps for multiple platforms
- Provides workspace plans for teams that need collaboration tools
Cons
- Caps virtual fax on the base plans
- Access to Zoom apps is limited on phone plans
- Limited CRM integrations compared to competitors like Nextiva
My expert opinion
Zoom Phone is often my choice for remote teams because of its tight integration with Zoom Meetings and collaboration tools. Managing calls, video meetings, and messaging in one familiar interface makes it especially convenient for remote teams. I also found its pricing structure flexible, with options for metered, unlimited, and global calling plans depending on business needs.
I recommend Zoom Phone for businesses that prioritize video conferencing and collaboration, especially for distributed teams working across regions. However, if you need deeper CRM integrations or advanced customer experience tools, a platform like Nextiva offers more robust capabilities in those areas.
- Unlimited auto-attendants: Set up unlimited call menus and IVR systems at no extra cost.
- Shared line appearance: Allow multiple users to manage calls from the same business number.
- Call monitoring and recording: Track and store calls for training and quality assurance.

Grasshopper: Best for simple business lines
Pros
- Provides core VoIP features like call forwarding and business texting
- Includes unlimited users on select plans at a flat monthly rate
- Charges no extra fees for toll-free or vanity numbers
Cons
- Limited third-party integrations
- Doesn’t come with video calling and team chat
- Lacks call recording
My expert opinion
Grasshopper often tops my list of business messaging apps, but what also stands out is how simple it is to set up and use. Unlike more complex VoIP platforms, Grasshopper focuses solely on essential phone features such as call forwarding, voicemail, and texting. I found this makes it especially appealing for freelancers or solo business owners who don’t want to deal with advanced configurations.
I recommend Grasshopper for solopreneurs and small teams that need a professional phone presence without paying per user. However, if your business requires collaboration tools like video meetings or team chat, you’ll quickly outgrow Grasshopper and should consider a more robust platform like RingCentral or a low-cost option like Zoom Phone.
- Custom greetings: Create professional call greetings or use Voice Studio recordings.
- Toll-free and vanity numbers: Get professional numbers at no additional cost.
- Business texting: Send and receive texts using your business number.

Talkroute: Best for flexible call routing
Pros
- Supports multiple users in monthly plans
- Offers professional in-house voiceover services
- Includes voice, messaging, and video communication
Cons
- Does not offer international outbound calling
- Provides 24/7 support only through email
- Lacks prebuilt third-party integrations
My expert opinion
When I evaluated Talkroute, its call handling flexibility, multiple phone numbers, and auto-attendants reflect a suite of features that make it easy for small teams to manage multiple incoming calls without needing a full contact center platform. I also found the built-in voiceover service useful for creating a more polished customer experience.
Because of these features, I recommend Talkroute for small businesses or teams that operate like mini call centers and need structured call routing. However, if your business requires international calling or CRM integrations, providers like Zoom Phone or RingCentral offer more advanced capabilities.
- Custom mailboxes: Create dedicated voicemail boxes for teams, numbers, or departments.
- Transfer codes: Transfer live calls instantly using simple dial codes.
- Call stacking: Handle multiple incoming calls by placing callers on hold with music or custom messages.

GoTo Connect: Best for customizable call management
Pros
- Includes unlimited calling to 50+ countries
- Scales from a phone system to a contact center
- Features an intuitive drag-and-drop dial plan editor
Cons
- Lacks AI capabilities in entry-level plans
- Includes limited toll-free minutes (1,000 shared)
- Pricing is not fully transparent
My expert opinion
While all providers on this list offer scalability, GoTo Connect specializes in call management and offers stair-step plans for growing businesses. The drag-and-drop dial plan editor also makes it easy to build complex call flows without technical expertise, which is a big advantage for small businesses managing multiple departments or locations.
Consequently, I recommend GoTo Connect for teams that want to customize how calls are handled as they grow. However, if you need international numbers or more built-in AI features, providers like RingCentral or Nextiva offer stronger capabilities in those areas.
- Dial plan editor: Customize call flows using a visual drag-and-drop interface.
- Call handling tools: Transfer, park, and route calls across teams and departments.
- Virtual fax manager: Send and receive faxes via email as digital attachments.

Google Voice: Best for Google Workspace users
Pros
- Integrates seamlessly with Google Workspace and Google Meet
- Offers a free-forever plan to anyone who has a Google account
- Supports desk phones via SIP compatibility
Cons
- Limited call management and routing capabilities
- Text messaging is limited to US-based users
- Requires a US phone number to verify a free Google Voice account
My expert opinion
Google Voice makes my list of the best VoIP apps because of how seamlessly it fits into the Google Workspace ecosystem. If you’re already using tools like Gmail, Google Calendar, and Google Meet, Google Voice feels like a natural extension rather than a separate system. I found it especially convenient to manage calls, messages, and schedules in a single environment without switching between platforms.
With that said, I recommend Google Voice for Google Workspace users who want a simple, integrated phone system without adding complexity or cost. However, if your team needs more advanced call handling, analytics, or multichannel communication tools, you’ll likely outgrow it and should consider providers like RingCentral or Nextiva.
*Google Voice also offers a Voice Only Starter plan for $10/month, which doesn’t require a Google Workspace subscription.
- SIP link support: Connect third-party desk phones and hardware.
- Spam call filtering: Uses AI to detect and block unwanted calls.
- Google Meet integration: Transition from voice calls to video meetings within the Google ecosystem.

Methodology: How I evaluated the best VoIP apps
To objectively assess the best VoIP apps, I created a rubric with criteria that reflect small-business priorities. These considerations include accessible pricing, call management features, user-friendliness, and customer support. I also evaluated the providers’ popularity amongst small business owners by collecting data from third-party review sites.
To learn more about how I evaluated different providers to identify the best VoIP application click the tabs below:
- Pricing (15%): Affordability is a key consideration in our evaluation, so I looked at the rates for each provider’s entry-level and second-tier plans and compared them with market rates. Higher points were given to vendors offering discounts for annual billing and volume users, affordable additional numbers, and no setup or termination fees.

Since businesses need a reliable platform, I factored in the uptime guarantee, awarding more points to those with 99.999% availability.

I assigned more points to providers with collaboration capabilities, such as video conferencing and team messaging.
