Best VoIP for small business: what grows your team's output?

Ready to build better conversations?

Simple to set up. Easy to use. Powerful integrations.

Get started

A potential customer calls your main business number at 2:30pm on a Tuesday. It rings six times and goes to voicemail that has not been checked in three days. The rep who handles inbound leads does not know the call happened. There is no log, no notification, no callback scheduled. The customer calls a competitor.

The best VoIP for small business is not the one with the longest feature list. The difference between a small business that runs on a professional cloud phone system and one that operates on personal mobiles and a landline is not team size or budget. It is one infrastructure decision that costs less than a desk phone per month per person to get right. Aircall grows with small businesses from first hire to 200+ seat teams by keeping AI, CRM integration, and calling tools in the plan rather than gating them behind enterprise tiers.

Key takeaways

• The right VoIP for a small business depends on team profile: outbound sales, inbound support, or basic professional calling are different decisions

• Check five things before signing: transparent pricing, CRM integration at base tier, AI features included or add-on, contract terms, and setup time

• Most small business teams can be live on a cloud VoIP system in under a day with no hardware and no IT support

• Number porting takes 1-3 weeks in the US; you operate on temporary numbers during that period so there is no downtime

What does a small business actually need from a VoIP phone system?

A small business needs a VoIP system that is live today, costs a predictable amount per seat, connects to the CRM the team already uses, and does not require a dedicated IT resource to set up or maintain. Everything beyond those four requirements is a feature decision that depends on whether the team is primarily doing outbound sales, inbound support, or basic professional calling.

VoIP (Voice over Internet Protocol) is a technology that routes phone calls over an internet connection rather than a traditional telephone network. For a small business, this means every rep makes and receives calls from a laptop or mobile using a softphone app, call data logs automatically, and the phone number belongs to the business rather than a personal device.

G2's VoIP research confirms that more than 60% of SMEs now prefer VoIP over traditional phone lines, with cost savings and scalability as the primary drivers. The businesses still on landlines or legacy PBX systems are not behind on technology, they are behind on the operational infrastructure that determines whether a small team can scale without hiring proportionally.

Five questions to ask before choosing a VoIP for small business

1. Is the pricing published per seat, or do I need a sales call to find out what it costs?

2. Can I set it up today without IT support, hardware, or a professional installation?

3. Does the CRM I use connect at the base tier, or only at a higher plan?

4. Are AI call summaries, call recording, and analytics included, or are they add-ons?

5. Can I leave on a monthly basis, or am I signing a 12-36 month contract?

Unbiased, a UK financial advice platform, deployed Aircall and measured the result directly. Daniel Piggott-Stewart, Head of Customer Support: "We've achieved a 23% uplift in our service level. It's like gaining an extra team member." That outcome, 23% more capacity from the same headcount, is what the right phone infrastructure produces for a small team. 

What are the 6 best VoIP phone systems for small businesses in 2026?

Each platform below is evaluated against the five criteria above. No platform wins every category. The right choice depends on whether your team is outbound sales, inbound support, a mix, or basic calling only.

1. Aircall

Aircall is a cloud phone system built specifically for small sales and support teams, with 250+ native CRM integrations, 24/7 support on all plans, and AI tools and power dialer available on the Professional plan ($50/user/month annually). Where competitors like Dialpad gate Salesforce and HubSpot to higher tiers and provide only 8 native integrations, Aircall's integrations are bidirectional and include HubSpot, Zendesk, and Pipedrive from the Essentials plan. The Salesforce integration and power dialer are on Professional, a distinction worth checking against the team's actual budget before signing.

Best for: Small sales and support teams of 3-50 seats that need AI, CRM integration, and outbound dialing tools in the core plan without enterprise contract terms or setup overhead.

Strengths:

• 250+ native CRM integrations, with HubSpot, Zendesk, and Pipedrive available on the Essentials plan and Salesforce on Professional; bidirectional sync means call data and outcomes reach CRM records automatically without rep action after each call

• AI Assist (call summaries, call scoring, sentiment analysis) is included on the Professional plan ($50/user/month annually); AI Assist Pro with real-time coaching is available as an add-on, giving sales managers structured coaching tools at a fraction of the cost of a standalone coaching platform

• 24/7 phone, email, and chat support on all plans with a named CSM from day one, not gated to higher tiers the way Dialpad gates 24/7 support to Pro and above

Limitations:

• 3-user minimum on all plans; a 2-person team pays for 3 seats at $90/month on Essentials or $150/month on Professional annually, which is the same floor as most alternatives in this category

• Power dialer and AI Assist are on the Professional plan ($50/user/month annually), not Essentials; a small outbound sales team that needs both will pay $50/user rather than $30/user, making Dialpad's $15 entry tier more cost-competitive for pure AI transcription needs

AI call summaries and coaching available in Aircall core plans covers what is in each tier. Aircall's native CRM integrations covers all 250+ connections and how bidirectional sync works. The full plan structure and what is included at each tier is at the Aircall call centre software page.

2. RingCentral

RingCentral is a full UCaaS platform that bundles voice, video, messaging, and conferencing, positioning itself as an all-in-one communications solution for businesses of any size. For small businesses that want to consolidate every communication tool under one vendor and are prepared for the implementation overhead that comes with that breadth, RingCentral is the most feature-complete option in this list. The trade-off is that its enterprise-first structure, quote-based pricing, annual contracts, and AI features behind higher tiers, creates the same procurement friction the article's five evaluation questions are designed to avoid.

Best for: Small businesses that have outgrown point solutions and need video conferencing, team messaging, and phone in one platform, with IT support available to manage setup and configuration.

Strengths:

• Full UCaaS capabilities including video meetings, team messaging, and conferencing alongside voice, one vendor for every communication channel if consolidation is the priority

• 300+ app integrations provide broad connectivity across business tools, more than most alternatives in this list

• Strong enterprise-grade compliance and security certifications relevant for small businesses in regulated industries such as healthcare or financial services

Limitations:

• No publicly listed pricing since 2023; teams must enter a sales process to get a quote, which directly conflicts with evaluation criterion one, and reported pricing can escalate significantly once AI, analytics, and contact centre features are added

• CRM integrations and AI features are available on higher tiers rather than at the base plan, meaning a small business that signs the entry plan may discover the features they actually needed require an upgrade after deployment

3. Dialpad

Dialpad is an AI-first communications platform where Dialpad AI, live transcription, real-time coaching prompts, and post-call summaries, is included at the base plan tier at $15/user/month. For small businesses leaving a basic VoIP specifically because AI summaries were an add-on, Dialpad resolves that gap at the lowest price point in this list. The significant caveat is integration depth: Dialpad has 8 native integrations versus Aircall's 250+, with Salesforce and HubSpot gated to the Pro plan and everything else routed through Zapier.

Best for: Small business teams prioritising AI transcription and call summaries at the lowest possible per-seat cost, where the team's CRM is not Salesforce or HubSpot and deep bidirectional sync is not a day-one requirement.

Strengths:

• Dialpad AI delivers real-time transcription, coaching prompts, and post-call summaries at the $15/user base plan, the most affordable entry point for AI-inclusive calling in this comparison

• Unlimited SMS on most plans and a strong mobile-first experience suited to distributed or remote small business teams

• Published pricing and monthly contract options available, satisfying evaluation criteria one and five without a sales conversation

Limitations:

• 8 native integrations versus Aircall's 250+; Salesforce and HubSpot are gated to the Pro plan, and everything else connects through Zapier, teams that need deep CRM logging from day one will encounter the same tier-gating problem Dialpad's entry pricing obscures

• 24/7 live support is gated to Pro and above; Standard plan customers receive business-hours support only, which matters for small businesses without in-house IT when a call routing issue needs immediate resolution

4. OpenPhone

OpenPhone (now rebranding as Quo) is a lightweight business phone product built explicitly for small teams, founders, and entrepreneurs who need a professional business number with shared inbox capabilities and basic integrations. Its positioning is accurate and honest: it is best for freelancers and small businesses where the phone is primarily a contact tool, not a workflow engine. For teams that currently use a personal mobile as their business number and need a step up to a shared, professional calling setup, OpenPhone is the simplest transition.

Best for: Solo founders, freelancers, and very small teams (1-5 seats) that need a professional shared business number with basic calling and SMS, and do not require deep CRM integration or outbound dialer tools.

Strengths:

• No user minimum and simple flat-rate pricing starting at $15/user/month, accessible for the smallest teams and freelancers who cannot meet the 3-user floor of platforms like Aircall

• Shared inbox and collaborative features, multiple team members can see and respond to calls and messages from the same business number, which is the primary operational gap for teams currently using a personal mobile

• Fast self-service setup with no hardware or IT support required; teams consistently report going live in under an hour

Limitations:

• CRM integration depth is limited to HubSpot, Slack, and Zapier connectors, not suited for teams on Salesforce or for workflows requiring bidirectional, automatic call logging to CRM records after every call

• No power dialer, no advanced call routing, and no AI call coaching; teams that start on OpenPhone and scale beyond basic calling needs typically find themselves evaluating a second platform within 12-18 months

5. Google Voice

Google Voice is Google's business phone product, available as part of Google Workspace or as a standalone add-on. For small businesses already standardised on Google Workspace, Gmail, Calendar, Meet, Drive, Google Voice is the most frictionless calling addition, operating within the same interface the team already uses daily. Outside of the Google ecosystem, its value proposition drops significantly: CRM integration is limited to Google's own products, and AI features are more basic than every other platform in this list.

Best for: Small businesses fully standardised on Google Workspace that need basic inbound and outbound calling within the same interface, with no outbound dialing, CRM logging, or AI coaching requirements.

Strengths:

• Native integration with Gmail, Google Calendar, and Google Meet, for teams whose entire workflow lives in Google Workspace, Voice adds calling without adding a new tool to manage

• Lowest entry price in this comparison at $10/user/month, accessible for teams with the tightest budgets and the most basic calling requirements

• Simple per-seat pricing with no complex feature gating at the tiers relevant to most small businesses

Limitations:

• CRM integration is effectively limited to Google's own ecosystem; Salesforce, HubSpot, and Zendesk connections are not native and require third-party connectors, making Google Voice unsuitable for sales or support teams that depend on accurate CRM logging

• No power dialer, no AI call summaries beyond basic transcription, and no call coaching; the platform is a calling tool, not a sales or support infrastructure

6. Zoom Phone

Zoom Phone is the calling product within Zoom Workplace, designed for teams already on Zoom for video meetings who want basic calling in the same interface. For small businesses where phone calls are infrequent and the primary need is a professional business number that works within an existing Zoom setup, it covers the requirement at a low per-seat cost. For small sales or support teams with real calling volume, the limitations are significant: no power dialer at any tier, AI features require the Workplace bundle rather than the standalone phone plan, and call metadata logged to CRM is basic at best.

Best for: Small businesses already on Zoom Workplace with light calling needs and no requirement for power dialing, CRM logging, or AI call summaries.

Strengths:

• Familiar Zoom interface for teams already using Zoom Meetings daily, no new platform to learn for basic calling functionality

• Published pricing with monthly contract options available; no enterprise sales process required for the standalone phone plan

• Easy add-on for teams that want calling without switching their video conferencing setup

Limitations:

• No power dialer at any tier; AI features require the Workplace bundle rather than the standalone phone plan, meaning teams that signed up for phone-only do not get AI without upgrading the full collaboration suite

• CRM integration logs basic call metadata only; Zoom Contact Centre's Salesforce and HubSpot connectors support voice only without AI data capture, making it unsuitable for sales teams that need complete, automated CRM records after every call

How do you choose the right VoIP for your specific small business?

The right VoIP for a small business comes down to three questions: what is the team primarily doing (outbound sales, inbound support, or basic calling), which CRM is already in use, and whether AI features are a day-one requirement or a future consideration. Three questions eliminate most of the 40+ platforms in this market before a single demo is requested.

Softphone is a software application installed on a laptop, mobile, or desktop that enables voice calls over the internet without physical hardware or a traditional desk phone. Every platform in this comparison includes a softphone app, meaning a small business can be live and calling from any device the moment the plan is activated. The practical difference for a small business is that setup takes minutes rather than days: no physical phone, no IT installation, no hardware cost.

• Outbound sales team (10+ calls per rep per day): power dialer, AI call summaries, CRM integration, and call coaching at the appropriate tier. A power dialer is an outbound calling tool that automatically dials the next number the moment a rep ends the previous call, eliminating manual dialing and increasing talk time from 15-20 minutes per hour to 40-50 minutes per hour. Aircall's power dialer is on the Professional plan ($50/user/month annually)

• Inbound support team (high call volume, helpdesk integration): IVR, call routing, ticketing system integration, call recording at base tier, Aircall or Dialpad

• Mixed sales and support: one platform handling both workflows without requiring two tiers or add-ons, Aircall

• Small professional team (basic calling, professional number, no complex routing): transparent pricing, mobile app, no contract lock-in, OpenPhone or Google Voice if on Workspace

• CRM already in use: confirm native integration at the specific tier you are evaluating before signing, not just "CRM integration" at the category level, Dialpad gates Salesforce/HubSpot to Pro; Aircall includes them at base

• No IT support available: confirm same-day self-service setup and phone or chat support, avoid platforms with business-hours-only support on the base plan

How do you set up VoIP for a small business?

Setting up a cloud VoIP system takes under a day for most small teams. The process is straightforward: sign up, download the softphone, configure routing, connect the CRM, and submit number porting for existing numbers. The phone system is usable immediately on temporary numbers while porting runs in the background.

Number porting is the process of transferring an existing business phone number from one provider to another while retaining the same digits. For small businesses, this means customers continue calling the same number they already have, with no service interruption, while the team operates on temporary numbers during the 1-3 week transfer window. US porting typically takes 1-3 weeks depending on the current carrier, and the team operates on temporary numbers during that window with no service interruption.

1. Sign up for a plan and create user accounts for each rep: most providers complete account creation in under 10 minutes

2. Download the softphone app on each rep's laptop and mobile: no hardware required, no IT installation

3. Configure call routing: set which rep or team receives inbound calls, define business hours, and create an IVR if needed, typically 30-60 minutes in the dashboard

4. Connect your CRM: follow the native integration setup in the provider's settings, confirm test calls log correctly to CRM records before going live

5. Submit number porting requests for existing business numbers: US porting takes 1-3 weeks; operate on temporary numbers during this period

6. Brief the team: every rep should know how the softphone works, how to log call outcomes, and what the CRM record looks like after a call before the first live call

CRM integration is the connection between the phone system and the customer relationship management platform, the mechanism that ensures every call, outcome, AI summary, and follow-up task reaches the correct CRM contact record automatically. Native integration writes data directly to the CRM when the call ends. Connector-based integration routes data through a third-party tool like Zapier, introducing sync delays, additional cost, and field-mapping constraints. For small businesses evaluating VoIP, the difference between native and connector-based CRM integration is the difference between a system that keeps itself current and one that requires manual maintenance to stay accurate.

What outbound calling looks like in a cloud phone system covers the practical transition from landline or legacy systems in more detail.

MySalesCoach research across 3,700+ sales professionals confirms that 76% of weekly-coached reps hit quota versus 47% coached quarterly. A VoIP platform with built-in AI call scoring and summaries gives small business sales managers the coaching infrastructure to review calls and provide structured feedback, without a dedicated enablement budget or a separate coaching tool subscription.

What do you need to check on security and data before signing?

• Call recording consent and storage: confirm whether the provider stores recordings on their infrastructure or yours, how long recordings are retained by default, and whether your state or country requires two-party consent before recording. California, Florida, and Illinois require all-party consent; most VoIP platforms include a configurable recording disclosure message that plays at the start of each call, confirm this is enabled before your first recorded call

• Data residency: if you have customers or team members in the EU, confirm the provider offers EU data residency or that their standard storage satisfies GDPR requirements for your use case

• Number ownership: confirm that phone numbers provisioned through the provider remain portable to a different provider if you leave. Some VoIP providers retain ownership of provisioned numbers, creating lock-in that is not visible at signup

Aircall data security and compliance covers certifications and data handling practices for teams with SOC 2, GDPR, and HIPAA requirements.

Frequently asked questions

What is the best VoIP for small business?

The best VoIP for a small business depends on team profile. Outbound sales teams need a power dialer and CRM integration in the base plan. Teams with basic inbound needs want transparent pricing and same-day setup. There is no single best option for every small business.

How much does VoIP cost for a small business?

Small business VoIP plans range from $10 to $40 per user per month for the base tier. Total cost depends on which features are included versus gated at higher tiers. Always check whether CRM integration, call recording, and AI features are included in the plan you are actually evaluating.

Can a small business set up VoIP without IT support?

Yes. Most cloud VoIP systems are designed for self-service setup: sign up, download the softphone app, configure routing in the dashboard, and connect your CRM. A 3 to 5 person team can be live and calling in under an hour with no hardware or IT involvement required.

What happens to existing phone numbers when switching to VoIP?

Existing business numbers can be ported to a VoIP provider. US number porting typically takes 1 to 3 weeks. During porting, the team operates on temporary numbers so there is no downtime. Confirm porting eligibility for specific numbers with the new provider before signing up.

Does VoIP work for remote or hybrid small business teams?

Yes. VoIP suits remote and hybrid teams well: calls go through a softphone app on any device with an internet connection. Every rep has the same calling experience in the office or at home, and call data flows to the CRM regardless of location.

What is the best phone system for small businesses?

For small businesses that need AI and CRM integration without enterprise contracts, Aircall grows with teams from first hire to 200+ seats with transparent pricing, 250+ native integrations, and AI call summaries in the core plan. Teams with basic calling needs may find OpenPhone or Google Voice sufficient at lower per-seat cost.

What we are

What grows from the right VoIP choice: the five criteria that narrow the field

The six platforms reviewed here cover every common small business use case: outbound sales with AI coaching, inbound support with helpdesk integration, basic professional calling for a small firm, and teams already embedded in Google Workspace or Zoom. None of them is right for every small business. All of them are better than a landline, a personal mobile, or a legacy PBX that has not been updated in five years.

Gartner confirms that 75% of B2B sales organisations will augment playbooks with AI-guided selling. Small business sales teams choosing a VoIP platform with built-in AI are making the same infrastructure investment that larger teams are prioritising at enterprise scale, at a fraction of the cost and without the implementation project.

The team that picks the right platform is the one that answered the five evaluation questions before the demo. Transparent pricing, CRM integration at the right tier, AI included rather than added on, contract flexibility, and same-day self-service setup: those five criteria narrow the field from 40+ providers to a short list in under ten minutes.
