Quo
A modern business phone app for calling and texting, with shared numbers, AI summaries and the Sona AI agent.
quo.com8.7
out of 10
Best for: Small teams and startups that want a simple, app-based business phone with texting.
Quo, from OpenPhone Technologies, is the easiest business phone system on this list to start using. Every plan includes a new or ported local or toll-free number per user, calling and texting to the US and Canada, voicemail transcripts, the Quo API and Sona, an AI agent that can handle calls using credits. The Starter plan costs $19 per user per month, and the apps feel closer to a messaging tool than a traditional phone system, which suits teams that text customers as much as they call.
The features growing teams need sit on Business at $33 per user: AI call summaries and transcripts, group calling, custom ring orders, call transfers, phone menus, auto recording, analytics and HubSpot and Salesforce integrations. Scale at $47 adds AI call tags and priority support. Every plan includes 1,000 automation credits, about 10 Sona calls, with more sold in tiers. Quo is not built for call centers, but for a small team it is the best mix of price and simplicity.
Standout feature
Calling, texting, a number per user and an AI agent start at $19 per user in a very easy app.
Use cases
Startups
Give each employee a business number on their phone
Outcome: Personal numbers stay private
Service businesses
Text customers from a shared number
Outcome: Faster replies, shared history
Sales teams
Log calls in HubSpot or Salesforce
Outcome: Complete activity records
Key features
- One new or ported local or toll-free number per user
- Calling and messaging to US and Canadian numbers
- Sona AI agent and ChatGPT and Claude MCP access
- AI call summaries, transcripts and auto recording on Business
- HubSpot and Salesforce integrations on Business
Pros
- Very easy to set up and use on mobile and desktop
- Texting is built in on every plan
- API access on all plans
Cons
- Phone menus and call transfers need the $33 Business plan
- Sona AI calls use credits beyond the 1,000 included
Rank 2 · Runner-up
Dialpad
An AI-powered communications platform for calls, messages and meetings, with sales and contact center plans.
dialpad.com8.6
out of 10
Best for: Teams that want built-in AI transcripts and summaries at a low entry price.
Dialpad has built AI into its phone system from the start, and it shows even on the cheapest plan. Standard, from $15 per user per month, includes unlimited calls, AI-powered meetings and built-in messaging, with real-time transcripts and instant call summaries, so nobody has to take notes. Pro at $25 adds key CRM integrations, 24/7 support and management across multiple offices.
Dialpad also sells dedicated plans for sales teams, from $39 per user with AI transcripts, call recording and CRM integrations, and up to $79 with live coaching, plus contact center plans from $89 per user. That makes it easy to start with basic phones and add specialist tools later without switching vendors. The trade-off is that CRM sync and multi-office features are not on Standard. For a team that values AI note-taking, Dialpad is the strongest value here.
Standout feature
Real-time transcripts and AI call summaries come on the entry plan from $15 per user.
Use cases
Small offices
Get automatic summaries of every call
Outcome: No manual call notes
Sales teams
Use local presence dialing and live coaching
Outcome: More answered calls and better pitches
Support teams
Move to a contact center plan later
Outcome: No platform switch as they grow
Key features
- Unlimited calls, AI-powered meetings and messaging
- Real-time transcripts and instant call summaries
- CRM integrations and 24/7 support on Pro
- Sales plans with local presence dialing and live coaching
- Contact center plans with quality management
Pros
- AI transcripts and summaries on the entry plan
- Grows from phones into sales and contact center tools
- Free trial
Cons
- CRM integrations need the Pro plan
- Sales and contact center tiers cost much more
Rank 3 · Also great
Nextiva
A business phone and customer experience platform with voice, video, texting, a basic CRM and XBert AI.
nextiva.com8.5
out of 10
Best for: Small and growing teams that want phones plus shared inboxes and light customer service tools.
Nextiva pairs a business phone system with customer experience tools that most rivals sell separately. Even NEXT Core, shown at $15 per user per month against a $23 standard price, includes unlimited voice and video, 100 business texts per user, shared team and personal inboxes, skills-based routing, a basic CRM and ticketing system, and a customer workflow builder. It also includes 50 AI transcriptions, 50 summaries and 50 AI answer assist conversations.
NEXT Engage at $25, discounted from $50, is the most popular plan for growing teams, and NEXT Scale at $75 is aimed at sales and service teams. Nextiva's XBert AI is billed at $1.50 per conversation on top. The discounts are significant, so confirm how long they last before you budget. For a small business that answers customer calls and messages from one place, Nextiva offers more service tooling per dollar than a plain VoIP app.
Standout feature
Even the entry plan includes shared inboxes, a basic CRM and ticketing alongside unlimited calling.
Use cases
Small service teams
Handle calls and texts in shared inboxes
Outcome: Nothing falls through the cracks
Customer support
Route calls by skill
Outcome: Callers reach the right person
Managers
Review AI call summaries
Outcome: Quick view of customer issues
Key features
- Unlimited voice and video
- 100 business text messages per user on Core
- Shared team and personal inboxes
- Basic CRM, ticketing and skills-based routing
- AI transcriptions, summaries and answer assist
Pros
- More customer service tools than most phone systems
- Discounted entry price
- AI features included in limited quantities
Cons
- XBert AI is billed at $1.50 per conversation
- Discounted prices may not last beyond the promotion
Rank 4
RingCentral
A unified communications platform for calls, meetings and chat, with AI assistant and receptionist options.
ringcentral.com8.5
out of 10
Best for: Growing and multi-site companies that want phones, video and messaging from one established vendor.
RingCentral is one of the most established business phone providers, and its Core plan bundles a lot: unlimited domestic calling, on-demand recording, 100 toll-free minutes, HD video meetings for up to 300 people, team chat and an AI Virtual Assistant. It costs $20 per user per month paid annually, or $30 monthly. Advanced, at $25, adds CRM integrations, support for multiple sites, reporting and more toll-free minutes and texts, and Ultra at $35 adds deeper analytics.
RingCentral also sells an AI Receptionist that answers and routes calls on any phone system, starting at $39. The weak spots for small businesses are texting limits, with only 25 SMS per user per month on Core, and the need to move to Advanced for CRM connections. For a company with several locations or a mix of office and remote staff, it remains the safest full-featured choice.
Standout feature
Calls, 300-person video meetings and chat come together in one plan from $20 per user.
Use cases
Multi-location businesses
Connect several sites on one system
Outcome: One directory and call routing
Hybrid teams
Call, meet and chat from one app
Outcome: Fewer separate tools
Front desks
Add the AI Receptionist to route calls

Key features
- Unlimited domestic calling and on-demand call recording
- HD meetings for up to 300 participants
- AI Virtual Assistant included, AI Receptionist as an add-on
- CRM integrations and multi-site support on Advanced
- LLM plugins and MCP connectors
Pros
- Phones, meetings and chat in one app
- Scales to large, multi-location companies
- Free trial
Cons
- Core includes only 25 SMS per user per month
- CRM integrations need the Advanced plan
Rank 5
Aircall
A cloud phone system for sales and support teams with AI Voice Agents and 250+ integrations.
aircall.io8.3
out of 10
Best for: Sales and support teams that live in their CRM or help desk.
Aircall is built for teams whose phone calls feed a CRM or help desk. More than 250 integrations sync calls, recordings and notes to the tools where your reps and agents already work. Essentials, at $30 per license per month, includes unlimited calls in the US and Canada, SMS and MMS, a shared inbox, call recordings with AI transcripts, IVR menus with business-hours routing and basic dashboards.
Every plan now includes AI Voice Agents that answer and resolve calls, with 50 minutes a month on Essentials, and you can buy AI Voice Agents on their own from a $100 monthly minimum. Professional at $50 adds automations, real-time analytics and more AI. Aircall costs more per seat than Quo or Dialpad, but for a sales or support team that needs every call logged in the CRM without effort, it is worth the premium.
Standout feature
More than 250 integrations make it the easiest phone system to wire into a CRM or help desk.
Use cases
Inside sales teams
Log every call in the CRM automatically

Support teams

Rank 6
Vonage
A business phone service with mobile and desktop apps, unlimited domestic calling and texting.
vonage.com8.2
out of 10
Best for: Small businesses that want a familiar VoIP provider at a promotional first-year price.
Vonage's business phone service is a straightforward option for small teams. The Mobile plan runs on desktop and mobile apps and includes unlimited domestic calling, SMS and MMS and voicemail. It lists at $19.99 per line per month, but a 12-month promotion brings it to $13.99, which is one of the lowest per-user prices among established providers. Higher plans are listed from $17.99 per extension, also with a promotional discount.
The things to watch are the promotion ending after a year and taxes and fees added on top, so budget on the regular price. Vonage's entry plan is also lighter on AI and collaboration features than Dialpad or RingCentral. If you want a well-known VoIP provider for basic calling and texting at a low first-year cost, it is a solid pick.
Standout feature
The 12-month promotion brings a line down to $13.99 a month from an established provider.
Use cases
Small offices
Replace landlines with app-based lines
Outcome: Calls on desk and mobile
Field teams
Use the mobile app for business calls
Outcome: One business number on the go
Cost-conscious owners
Start on the 12-month promotion
Outcome: Lower first-year bill
Key features
- Desktop and mobile apps
- Unlimited domestic calling
- SMS and MMS
- Voicemail
- Higher plans for larger teams
Pros
- Low first-year price with the 12-month promotion

- Established provider
Cons
- Promotional price rises after 12 months
- Taxes and fees are added on top
Rank 7
Voxbi
A cloud PBX hosted in Europe with call flows, IVR, recording, AI transcripts and a free plan for small teams.
voxbi.com8.2
out of 10
Best for: European businesses that want a GDPR-focused cloud PBX with very low per-user fees.
Voxbi is a cloud PBX hosted in Europe, aimed at businesses that care about data residency and want full phone system features at low cost. It covers call flows and IVR, routing, menus and queues, numbers and porting in many countries, call recording, mobile and desktop apps, analytics, AI transcripts and summaries, and an AI receptionist that answers your own numbers. It integrates with Odoo and Microsoft 365, with Microsoft Teams as a €50 a month add-on.
The pricing model is different from US providers. Per-user fees are tiny, from €1.20 a month on Starter to €3.10 on Plus AI, but calls are billed per minute at destination rates and paid plans do not include a phone number, which costs €2.00 a month. A free plan supports up to three users with a small call credit, and managed plans run by Voxbi start at €5.20 per user. For a European business, it is excellent value; US companies will find simpler all-inclusive pricing elsewhere.
Standout feature
A Europe-hosted cloud PBX with a free plan for three users and paid seats from €1.20 a month.
Use cases
European SMBs
Run a GDPR-focused cloud PBX
Outcome: Data kept in Europe
Odoo users
Click to call and log calls in Odoo
Outcome: Calls tied to CRM records
Tiny teams
Use the free plan for up to three people
Outcome: Business phone with no subscription
Key features
- Call flows, IVR, routing, menus and queues
- Numbers in many countries and number porting
- Call recording and AI transcripts and summaries on Plus AI
- AI receptionist on your own numbers
- Odoo and Microsoft 365 integrations, Microsoft Teams add-on
Pros
- Free plan for teams of up to three
- Very low per-user fees
- Hosted in Europe with GDPR and ISO focus
Cons
- Calls are billed per minute on top of plans
- Prices are in euros, and paid plans do not include a phone number
Rank 8
Grasshopper
A virtual phone system that adds a business number and extensions to the phones you already have.
grasshopper.com7.9
out of 10
Best for: Solo owners and very small businesses that want a separate business number on their cell phone.
Grasshopper is the simplest way for a solo owner to separate business calls from personal ones. It gives you a business number that rings on the phones you already have, with extensions so callers can reach different people or departments. True Solo costs $14 a month billed annually, or $168 a year, for one user, one number and one extension.
What makes Grasshopper unusual is flat pricing for teams. Solo Plus, $25 a month billed annually, shares a single inbox across unlimited users with one number and three extensions, and Small Business, $55 a month billed annually, includes unlimited users, four numbers and unlimited extensions. It lacks the AI, video and deep integrations of RingCentral or Dialpad, but if you only need a professional number and simple routing, it is hard to make easier.
Standout feature
Flat pricing with unlimited users on Solo Plus and Small Business, with no per-seat fees.
Use cases
Solo consultants
Add a business number to a personal cell
Outcome: Work and personal calls separated
Small family businesses
Share one number across the team
Outcome: No per-user fees
Growing shops
Add extensions for departments
Outcome: Callers reach the right person
Key features
- Business phone number on your existing phones
- Extensions for departments or staff
- Shared inbox on Solo Plus with no per-user cost
- Up to 4 numbers on Small Business
- 7-day money-back guarantee
Pros
- Very simple to set up
- Unlimited users on Solo Plus and Small Business
- Flat pricing rather than per seat
Cons
- Fewer features than full VoIP systems
- Best prices require annual billing
Rank 9
GrowOutly
A calling platform with a power dialer, CRM, texting and support call routing in one subscription.
growoutly.com7.5
out of 10
Best for: Outbound sales teams and appointment setters that need a dialer and phone numbers together.
GrowOutly is a phone system built around outbound sales. It combines a power dialer with calling queues, a CRM, texting, email and a lead scraper in one subscription, and it also offers support call routing so customers can call one number and reach an available expert. A compliance feature screens and suppresses known repeat TCPA plaintiffs and serial lawsuit claimants, which matters for teams making many cold calls.
The Base plan costs $119 a month for one user with 300 calling minutes, 100 SMS, one virtual number and 500 emails, and Pro at $319 and Essentials at $819 cover sales teams of two to ten reps and more. There is no setup fee and you can cancel anytime. As a general business phone system it is expensive, but for a team that would otherwise pay for a dialer, a CRM and texting separately, it bundles them well.
Standout feature
It screens known repeat TCPA plaintiffs before you dial, alongside a power dialer and CRM.
Use cases
Appointment setters
Work a call queue with a power dialer
Outcome: More dials per hour
Outbound teams
Screen numbers against TCPA litigators
Outcome: Lower legal risk
Service companies
Route support calls to an available expert

- Base includes only 300 calling minutes and one user
Frequently asked questions
+What is a business phone system?
It is a service that gives your company phone numbers, extensions, call routing, voicemail and often texting and video, usually through apps on computers and mobile phones instead of desk hardware. Most modern systems run over the internet, known as VoIP.

Most VoIP systems on this list cost $15 to $35 per user per month. Dialpad and Nextiva start at $15, Quo at $19 and RingCentral at $20 paid annually. Grasshopper starts at $14 a month billed annually, and Voxbi has a free plan for up to three users.
+Can I keep my existing business number?
Yes, almost every provider can port your existing number. Porting can take days to weeks, so keep your old service active until the transfer finishes.
