9 Best VoIP Phone Services of 2026

This list is for small businesses moving from landlines or mobile phones to a cloud phone system and comparing what one line really costs. We ranked each service by value first, then features, then ease of use, and looked closely at per-line prices, included toll-free minutes and text messages, and the add-ons that raise the bill. Prices are the cheapest paid plan in USD as shown on each vendor's page on the check date; where a page showed another currency or no public price from our location, the price is marked pending. We compared documented features and published prices.

   Best forSmall teams that want AI call summaries included in the entry price.

   Dialpad ranks first because its entry plan bundles what small businesses usually pay extra for. The pricing page lists Standard at $15 per user per month with annual billing, or $27 month to month, and describes it as unlimited calls, AI-powered meetings and built-in messaging. Dialpad's FAQ says the Connect product includes real-time call transcription, voicemail transcription, AI Recaps with call summaries and action items, and real-time analytics. Pro at $25 adds key CRM integrations, 24/7 customer support and multi-office management, so a team that needs Salesforce or HubSpot logging has to step up. Enterprise adds SSO, user access controls and unlimited office locations at a custom price. Dialpad supports international local numbers in over 50 countries and runs on desktops, phones, tablets and desk phones. The page warns that prices can vary by region and currency, so non-US buyers should confirm their quote.

   • ✓$15 per user on annual billing is one of the lowest verified entry prices here
   • ✓Runs on desktop, phone, tablet and desk phones

   • ✕Month-to-month billing raises Standard to $27 per user

   Best forOwner-run and small teams that call and text customers in the US and Canada.

   Quo, the renamed OpenPhone, is the most direct option here for a small business that wants a proper number on every phone. Starter costs $15 per user per month billed annually at $180, or $19 month to month, and every plan includes one new or ported local or toll-free number per user, calling and messaging to US and Canadian numbers, voicemail transcripts, the Quo API and email ticket support. Every plan also includes the Sona AI agent with 1,000 automation credits, which the page equates to 10 calls; paid credit tiers start at $25 a month for 4,000 credits, and overage runs from $1.00 down to $0.45 per call. Business, at $33 per user on monthly billing, adds AI call summaries and transcripts, group calling, custom ring orders, call transfers, phone menus, HubSpot and Salesforce integrations and auto call recording. Scale at $47 adds AI call tags and priority support. The limit is geography: included calling and texting are for US and Canadian numbers.

   • ✓Short, clear plan list with a number included for each user
   • ✓$15 per user on annual billing matches the lowest verified entry price here
   • ✓AI agent is included with a small free credit allowance

   • ✕Included calling and texting cover US and Canadian numbers only
   • ✕Phone menus and call transfers need Business at $33 per user monthly
   • ✕Extra Sona calls cost from $0.45 to $1.00 each depending on the credit tier

   AI credits:

   1,000 included, 1 call equals 100 credits

   Bottom line: Quo is the easiest way to give every team member a business number for $15 a user. Teams that need phone menus or call transfers should budget for Business.

   Best forSmall teams that want phone, texting and a basic CRM and ticketing system in one plan.

   Nextiva ranks third because its $15 NEXT Core plan bundles more than calling. The pricing page lists Core at $15 per user per month on annual billing against $23 monthly, with unlimited voice and video, 100 business text messages per user, team collaboration, skills-based routing, a basic CRM and ticketing system, shared team and personal inboxes. Core also includes 50 AI transcriptions, 50 AI summaries and 50 AI Answer Assist conversations. NEXT Engage at $25 adds live chat and a chatbot, 500 texts per user, 2,000 toll-free inbound minutes, three shared team inboxes, SSO with Okta or Microsoft Entra ID and virtual faxes. NEXT Scale at $75 removes the text and AI caps and adds 10,000 toll-free inbound minutes. XBert, Nextiva's AI agent, is billed at $1.50 per conversation on top of seats. The page also advertised a limited-time switching offer of up to 12 months free, so ask sales what applies.

   • ✓Entry plan includes a basic CRM and ticketing system with the phone line
   • ✓Clear text and AI usage allowances listed per plan
   • ✓Engage adds 2,000 toll-free inbound minutes for businesses with a toll-free number

   • ✕NEXT Core does not list toll-free inbound minutes

   Ooma Office is the lowest-commitment choice on this list. Essentials costs $19.95 per user per month with no contract, and includes unlimited calling in the US, Canada, Mexico and Puerto Rico, a virtual receptionist, the mobile app, digital fax and one free toll-free number with 500 minutes of inbound calls per month. That makes it a clean landline replacement for a shop or office. The limits show up on Essentials: there is no desktop app and no texting. Pro at $24.95 adds the desktop app, up to 250 texts a month, video meetings for up to 25 people, call recording and enhanced call blocking. Pro Plus at $29.95 adds AI transcriptions and insights, CRM integrations with tools such as Clio, Square and NexHealth, up to 1,000 texts, team chat, hot desking and call queuing.

   • ✓No contract on any self-serve plan

   Best forGrowing businesses with several sites that want the deepest feature set.

   RingCentral has the most complete feature set in this group and the clearest minute and text allowances. RingEX Core costs $20 per user per month on annual billing, or $30 paid monthly, and includes unlimited domestic calling, on-demand call recording, 100 toll-free minutes, 25 SMS per user a month, HD meetings for up to 300 participants and the AI Virtual Assistant. Advanced at $25 adds CRM integrations, multi-site support, core reporting, 1,000 toll-free minutes and 100 SMS per user. Ultra at $35 raises those to 10,000 minutes and 200 SMS and adds unlimited storage and webinars. The value score is lower because the AI Receptionist starts at $39 as an add-on, the Call Queues Booster is $35, and RingCentral notes that regulatory fees and E911 charges may apply on top. The free trial is limited to five users and two desk phones, and SMS is not available during the trial.

   • ✓AI Virtual Assistant is included on every RingEX plan
   • ✓Largest toll-free minute allowances on the upper tiers
   • ✓Multi-site and CRM features at $25 per user on Advanced

   • ✕$30 per user on monthly billing is high for an entry plan

   Best forSmall businesses that want the lowest first-year price per line.

   Vonage Business Communications has the lowest verified first-year price here. The Mobile plan was listed at $13.99 per line per month as a 12-month promotion against a regular $19.99, plus taxes and fees, and covers the desktop and mobile apps, unlimited domestic calling, SMS and MMS, voicemail, number porting and a virtual receptionist. Mobile does not support desk phones. Premium, promoted at $20.99 against $29.99, adds VoIP desk phone support, unlimited video meetings for up to 200 participants, team messaging, single sign-on and the VBC App Center with more than 20 integrations for CRMs and productivity tools. Advanced, promoted at $27.99 against $39.99, adds 15 hours a month of on-demand call recording, visual voicemail with transcription and call groups. The ranking reflects the promotion: after the first year, Vonage's regular prices sit above Dialpad, Quo and Nextiva for comparable features, so compare the second-year cost too.

   • ✓$13.99 per line is the lowest verified first-year price on this list
   • ✓Texting and a virtual receptionist are included on the cheapest plan
   • ✓Plans are priced per line, which suits very small teams

   • ✕The headline prices are 12-month promotions against $19.99 to $39.99 regular

   Best forTeams already using Zoom for meetings that want phone in the same app.

   Zoom Phone suits businesses that already run meetings on Zoom and want calls in the same app. The pricing page lists Global Select, which gives unlimited calling within one of 48 available countries and territories, plus bundles that combine Phone with Zoom Workplace Pro or Business so one license covers meetings and calls. Global Select is sold for 1 to 99 licenses and the Business Plus bundle for up to 250. Add-ons include extra local, toll-free or international numbers, unlimited international calling to more than 15 countries and regions, and a Customer Engagement Pack with call queue analytics for teams that run a small call center. From our location the pricing page showed only Polish zloty, so we have not listed a USD price; check the US page before you buy. On features Zoom is competitive, but extra numbers and international calling add to the per-user cost.

   • ✓Phone, meetings and chat in the Zoom app many teams already use
   • ✓Unlimited calling can be based in one of 48 countries
   • ✓Bundles cover meetings and phone on one license

   • ✕Our check showed prices only in zloty, so the USD price is pending
   • ✕Extra phone numbers and international calling are paid add-ons
   • ✕Call queue analytics need the separate Customer Engagement Pack

   Plans:

   Global Select, Workplace Pro + Global Select, Workplace Business Plus

   Calling:

   Unlimited within one of 48 countries and territories on Global Select

   Licenses:

   1 to 99 on Global Select, up to 250 on Business Plus

   Bottom line: Zoom Phone makes sense when your team already lives in Zoom meetings. Confirm the US price and the add-ons you need before comparing it with Dialpad or RingCentral.

   Best forSales and support teams of three or more that work from a CRM or help desk.

   Aircall is built for teams whose calls feed a CRM or help desk, and it shows in the integration list. Essentials starts at $30 per license per month billed annually, with a minimum of three licenses, and includes unlimited calls within the US and Canada, SMS and MMS, a shared team inbox, call recordings with AI transcripts, IVR with business-hours routing, basic dashboards with six months of data, more than 250 integrations and 50 minutes of AI Voice Agents a month. Professional at $50 adds AI call summaries and conversation intelligence, smart routing using CRM data, queue callback, a power dialer for up to 1,000 numbers and outbound campaigns. Aircall says annual plans are 25% cheaper than monthly ones. The low value score reflects the price floor: three licenses at $30 means at least $90 a month, which is more than a solo owner or two-person shop needs to spend on Dialpad or Quo.

   • ✓Deep CRM and help desk integrations on the entry plan
   • ✓Call recording and AI transcripts included from Essentials
   • ✓Professional adds a power dialer for outbound teams

   • ✕Every plan requires at least three licenses
   • ✕$30 per license is the highest verified entry price here
   • ✕Dashboards on Essentials keep only six months of data

   Cheapest paid plan:

   Essentials, $30 per license per month billed annually

   Minimum users:

   3 on Essentials and Professional, 25 on Enterprise

   Annual discount:

   25% compared with monthly pricing

   AI Voice Agents:

   50 minutes a month on Essentials; standalone from $99 per month

   Bottom line: Aircall is a strong fit for small sales or support desks that live in a CRM. Very small businesses will pay for seats they do not use because of the three-license minimum.

   Best forBusinesses that call abroad often and prefer a sales-led setup.

   GoTo Connect has a strong base plan for businesses that call internationally, but it no longer shows a public price. The Phone System plan includes free calls to 50 countries, unlimited auto attendants and call queues, customizable dial plans, video meetings with up to 250 participants, mobile and desktop apps and 24/7 support with a stated 99.999% reliability. Phone System plus AI Receptionist adds a 24/7 AI virtual receptionist with 100 AIR credits, call routing and transfer by name, answers from an FAQ or knowledge base, caller detail capture with email and SMS follow-up and multilingual voices. The Customer Experience and CX Complete plans add WhatsApp, social, SMS campaigns, web chat, surveys, a team inbox and integrations with ServiceNow and Zendesk. Every plan on the pricing page leads to a sales conversation, so we could not verify a starting price, and that lack of transparency is why GoTo sits last on value.

   • ✓Calls to 50 countries are included in the base phone plan
   • ✓Unlimited auto attendants and call queues
   • ✓24/7 support with a 99.999% reliability claim

   • ✕No public price; every plan goes through sales
   • ✕AI receptionist credits beyond 100 cost extra
   • ✕Customer experience channels need a higher CX plan

   Plans:

   Phone System, Phone System + AI Receptionist, Customer Experience, CX Complete

   International calling:

   Free calls to 50 countries

   Meetings:

   Up to 250 participants

   Pricing:

   Contact sales, no public price on the check date

   Bottom line: GoTo Connect is worth a quote if you call many countries and want an AI receptionist. Small businesses that want a published per-line price will find it easier to buy elsewhere.
