Search "best VoIP software" and you get vendor homepages, softphone downloads, and ranked lists that rarely tell you whether an office manager at a ten-person company found the tool easy to live with every day, so I went to the reviewers instead. Vendors rank themselves first, and most roundups do not show you the review data behind their picks. The eight products that met this standard (800.com, Google Voice, OnSIP, RingEX, Ringover, Unitel Voice, Wildix, and Zoom Phone) are evaluated below on ease of use, call quality, support, and how consistently each one performs the job it is built for. The pattern across 1,021 reviews is consistent: reviewers care most about ease of use and responsive support, and their complaints are about call quality, app glitches, and plan limits more than price. In my view, that last point is the most underestimated factor in this category: buyers compare price lists, while reviewers keep writing about whether calls connect cleanly. Products are listed alphabetically. Inclusion is based on the methodology at the bottom of this article. Quick take In my analysis, OnSIP has the highest rating at 4.86 and the best support score (4.96), but on only 28 reviews, while Ringover is the best validated, with 429 reviews at 4.83. 800.com (4.76 on 241 reviews) suits small teams that mainly need toll-free numbers, and Google Voice is the free starting point. Zoom Phone and RingEX have the lowest ratings on this list (4.36 and 4.33), and RingEX has the weakest support score (4.04). ## The 8 best VoIP software platforms at a glance Here is how all eight stack up on the metrics that matter most when choosing VoIP for small business, all based on Capterra reviews from the last 24 months. What stood out when I lined them up is that the two highest ratings sit on very different sample sizes, so I would read ratings and review counts together. | Product | Rating | Reviews analyzed | Best for | Starting price | | --- | --- | --- | --- | --- | | [800.com](https://www.capterra.com/p/208208/800-com/) | 4.76/5 | 241 | Toll-free and vanity numbers | $23/month flat, Personal plan | | [Google Voice](https://www.capterra.com/p/210592/Voice/) | 4.47/5 | 32 | Free second business line | $10/user/month, Starter plan (free version available) | | [OnSIP](https://www.capterra.com/p/158706/OnSIP/) | 4.86/5 | 28 | Hands-on phone support | $18.95/user/month, Unlimited plan | | [RingEX](https://www.capterra.com/p/242188/RingCentral-MVP/) | 4.33/5 | 24 | Mobile calling and fax | $30/user/month, Core plan | | [Ringover](https://www.capterra.com/p/169627/RingOver/) | 4.83/5 | 429 | CRM-connected sales and support teams | $29/user/month, Smart plan | | [Unitel Voice](https://www.capterra.com/p/172777/UniTel-Voice/) | 4.75/5 | 20 | Budget-friendly small teams | $9.99/month flat, Start-Up plan | | [Wildix](https://www.capterra.com/p/218251/Wildix/) | 4.71/5 | 205 | Partner-deployed unified communications | Custom quote | | [Zoom Phone](https://www.capterra.com/p/208535/Zoom-Phone/) | 4.36/5 | 42 | Teams already on Zoom | Custom quote | Ratings and review counts reflect verified Capterra reviews in our dataset, October 2024 to October 2026. Read small samples carefully When only 20 to 30 reviews back a rating (OnSIP, Unitel Voice, RingEX), treat it as directional and ask the vendor for 2 customer references of a similar size. ## How I chose this list To build this list, I selected products based on the following criteria: - **Review volume:** Have at least 20 verified Capterra reviews in the last 24 months. - **Rating floor:** Have an overall Capterra rating of 4.2 or higher, based on data from the last 24 months. - **Category qualification:** Appear on Capterra Shortlist for VoIP software (2026) and be used by reviewers as a general business phone or VoIP system. The raw pull covered 159 products, including meeting tools such as Microsoft Teams, Zoom Workplace, and Google Meet that make up nearly half of the reviews but are not on Capterra Shortlist for VoIP software, so I set them aside. The data I analyzed skews toward U.S. small businesses and, for Ringover and Wildix, European reviewers, so enterprise or multi-country teams should weight these scores differently. Three picks (800.com, Google Voice, and Wildix) serve narrower needs than a full phone system, so each section says who they fit best. ## 1\. [800.com](https://www.capterra.com/p/208208/800-com/): Best for toll-free and vanity numbers _800.com dashboard showing business numbers, call forwarding rules, and call tracking_ [800.com](https://www.capterra.com/p/208208/800-com/) has the second-highest rating among the high-volume picks at 4.76 across 241 reviews, and its audience is the smallest-business end of VoIP: 76% of reviewers are at companies with 1–50 employees, 40% are owners or CEOs, and 89% are in the U.S. They use it to get a toll-free or vanity number quickly and route calls to a cell phone. It earns its place on simplicity and value. Reviewers rate it 4.79 for ease of use and 4.71 for value for money, behind only OnSIP's 4.78 on value. If you want a professional number and call forwarding without an IT project, it is a strong fit. If you need desk phones and deeper team features, look at the full phone systems below. #### Trial/Free Version - Free Trial - Free Version #### Device Compatibilty **Why users like it:** - **Ease of use:** Mentioned in 126 of 241 reviews - **Setup and porting:** Mentioned in 70 of 241 reviews - **Value:** Mentioned in 42 of 241 reviews **Key features:** - **Toll-free, local, and vanity numbers:** Activates a number in minutes or ports an existing number. - **Call forwarding and routing:** Supports standard, sequential, or simultaneous forwarding, custom hours, and extensions. - **Call tracking and analytics:** Assigns numbers to marketing campaigns to show which source produces calls. **Limitations to know:** - **SMS verification:** Mentioned in 23 of 241 reviews as a slow step before texting works. - **Standalone use:** Forwarding needs another active number, and there is no desktop app. - **Minute cap:** The entry Personal plan includes 1,000 minutes, so check usage first. **What a verified Capterra reviewer says:** "800.com has been very easy to set up and use for our business. We use multiple tracking numbers for different marketing campaigns, which makes it simple to see exactly where our calls and leads are coming from. The dashboard is straightforward, adding new numbers is quick, and the call tracking gives us a much better understanding of which marketing campaigns are actually producing results." Matthew Picanco, Director of Marketing Sales, Umbrella Exteriors, August 2026 **Bottom line:** _One founder wrote that he would prefer "a more standalone experience" because he has to use another active phone number to receive forwarded calls (Christopher Giron, Founder, Volkano LLC, September 2026), and another reviewer wants a desktop app (Justin Pitter, Owner, Eco Pro Chem, July 2026). If you are choosing between it and Ringover, see Capterra's_ [_Ringover vs. 800.com comparison_](https://www.capterra.com/compare/169627-208208/RingOver-vs-800-com)_. For small teams that mostly need a credible toll-free number, its 4.76 rating and 4.71 value score make it a low-risk start._ ## 2\. [Google Voice](https://www.capterra.com/p/210592/Voice/): Best for a free second business line _Google Voice web app showing calls, texts, and voicemail transcripts in one inbox_ [Google Voice](https://www.capterra.com/p/210592/Voice/) is the only pick here with a free version, and its reviewers read like solo operators and very small teams: 15 of 32 are at companies with 1–10 employees, 29 of 32 are in the U.S., and several are case workers, therapists, and owners who want a separate number without carrying a second phone. It earns its place as the simplest way to get a second number that works on a phone and a computer. Reviewers rate it 4.71 for value for money, tied with 800.com, and 4.59 for ease of use. Its 4.28 functionality score is the lowest of the eight, which fits a tool built for calling and texting rather than team call handling. #### Trial/Free Version - Free Trial - Free Version #### Device Compatibilty **Why users like it:** - **Second line:** Mentioned in 16 of 32 reviews - **Price:** Free or affordable plans, mentioned in 9 of 32 reviews - **Ease of use:** Mentioned in 8 of 32 reviews **Key features:** - **Multi-device calling and texting:** Handles calls, texts, and voicemail from a phone or computer. - **Voicemail transcription:** Converts voicemail to text so you can scan messages quickly. - **Ring groups and auto attendant:** Available on the paid Standard plan at $20 per user per month. **Limitations to know:** - **Call glitches:** Delays and missed calls came up in 10 of 32 reviews, so test in a trial given the small sample. - **Feature limits:** Mentioned in 7 of 32 reviews, including no multiple numbers on one account and no out-of-office replies. **What a verified Capterra reviewer says:** "A great option for an alternate phone line, the setup is fast and easy, it even allows you to choose your own number. I love that you can have it in your computer and your phone, and both are sync! Managing my texts and messages is easier from my laptop, so that's a great plus. It is a free service, so is the best bang for your buck, as long as you have internet access, you have service." Jesus Gonzalez, Case Worker, Bee Mindful, June 2026 **Bottom line:** _Spam is a recurring annoyance: one reviewer wrote "I always get spam calls" and plans to drop it from their tech stack (Tyra Overby, People Operations Specialist II, Amperity, May 2026). Capterra's paid plans start at $10 per user per month, and you can also browse_ [_free VoIP tools_](https://www.capterra.com/voip-software/s/free/)_. Teams that need shared call handling will outgrow it, but for a solo practice it is a strong, low-cost first line._ ## 3\. [OnSIP](https://www.capterra.com/p/158706/OnSIP/): Best for hands-on phone support _OnSIP admin portal showing extensions, call routing, and call reporting_ [OnSIP](https://www.capterra.com/p/158706/OnSIP/) has the highest overall rating on this list at 4.86 and the strongest support score, 4.96 out of 5, but it has only 28 reviews in this dataset, so treat its numbers as directional. Its reviewers are U.S. small organizations: all 28 are in the U.S., 16 are at companies with 11–50 employees, and titles skew toward presidents, CEOs, and directors of operations or administration. It earns its place on one thing: when something goes wrong, you can call and reach a person. 24 of 28 reviewers mention support or service in their pros. If you value phone support and a dependable business VoIP system over a long feature list, it is a strong fit for small offices, schools, and nonprofits. #### Trial/Free Version - Free Trial - Free Version #### Device Compatibilty **Why users like it:** - **Ease of use and setup:** Mentioned in 12 of 28 reviews - **Call quality and reliability:** Mentioned in 7 of 28 reviews **Key features:** - **Softphones and mobile apps:** Takes office calls on a computer or smartphone from anywhere. - **Auto attendant and call routing:** Supports ring groups, extensions, and call transfer. - **Admin portal and CRM integrations:** Includes role-based permissions, call reporting, and connections to HubSpot, Zendesk, and Odoo. **Limitations to know:** - **App and connection glitches:** Mobile app sign-ins, delays, and dropped sessions came up in 7 of 28 reviews, so confirm in a trial. - **Learning curve:** Mentioned in 4 of 28 reviews, mostly for advanced call flows and web app settings. **What a verified Capterra reviewer says:** "OnSIP is incredibly reliable and easy to use. Call quality is consistently clear, and the system is simple to manage, even without advanced technical knowledge. The customer support team is responsive and knowledgeable, which makes a big difference when questions come up." Marianna Pittman, Executive Manager, Pathway Mortgage Group, December 2025 **Bottom line:** _Remote staff can be the weak spot: one front desk team reported that remote users "often have to log out and login again to keep their ONSIP working remotely" (Sheila Sullivan-Passwaters, Front Desk Services, McCarthy & Cox, December 2025). Capterra lists the Unlimited plan at $18.95 per user per month and a Basic plan at $49.95 flat per month, so the cheaper option depends on headcount and call volume, and you can compare it with Ringover in Capterra's_ [_Ringover vs. OnSIP comparison_](https://www.capterra.com/compare/158706-169627/OnSIP-vs-RingOver)_. For small offices that value a person on the phone, its 4.96 support score is the strongest on this list._ ## 4\. [RingEX](https://www.capterra.com/p/242188/RingCentral-MVP/): Best for mobile calling and fax _RingEX desktop app showing calls, messages, and voicemail in one window_ [RingEX](https://www.capterra.com/p/242188/RingCentral-MVP/) has the lowest overall rating on this list at 4.33 across 24 reviews, and the weakest support score, 4.04. Its reviewers skew larger than the rest: 9 of 24 are at companies with 201–500 employees, and titles include operations managers, administrators, a CMO, and a VP of operations. It is the household-name option: a full cloud phone system from RingCentral with calling, texting, voicemail, and meetings on desktop and mobile. Reviewers rate its functionality 4.58, above Zoom Phone (4.50) and Google Voice (4.28), but its value (4.17) and support (4.04) scores are the lowest of the eight. #### Trial/Free Version - Free Trial - Free Version #### Device Compatibilty **Why users like it:** - **Ease of use:** Mentioned in 10 of 24 reviews - **Support:** Mentioned in 7 of 24 reviews - **Mobile and desktop apps:** Mentioned in 6 of 24 reviews **Key features:** - **Desktop and mobile apps:** Handles calls, voicemail, and texting from any device. - **SMS, MMS, and internet fax:** Fax is included from the Advanced plan. - **Call recording and CRM integrations:** Auto call recording and access to Salesforce and Zendesk start on the Advanced plan. **Limitations to know:** - **Call and app glitches:** Lag, dropped calls, and notification bugs came up in 5 of 24 reviews, so test in a demo. - **Support, sales, and billing friction:** Mentioned in 3 of 24 reviews, including one CTO who found key SMS features required a paid add-on that was not explained during the sales process. **What a verified Capterra reviewer says:** "Implementation was straightforward and it allowed our teams to get up and running smoothly in no time at all making direct dials, and routing inbound calls via queues. Administration is easy, support is responsive, and the overall value is tough to beat." Nick Ward, Operations Manager, Tort Intake Professionals, June 2026 **Bottom line:** _Capterra lists Core at $30 per user per month, with Advanced at $35 adding auto call recording and internet fax. One reviewer rated it 2 stars after being "forced into RingCentral Meetings which has been regularly awful as far as video quality and issues" (Bonnie Beauchamp, Digital Systems Manager, Atlanta Mission, June 2026), so test video separately and compare it with Ringover in Capterra's_ [_Ringover vs. RingEX comparison_](https://www.capterra.com/compare/169627-242188/RingOver-vs-RingCentral-MVP)_. For larger teams that want mobile calling, texting, and fax in one app, it is a fit._ ## 5\. [Ringover](https://www.capterra.com/p/169627/RingOver/): Best for CRM-connected sales and support teams _Ringover app showing call history, contact details, and CRM-linked call logs in one workspace_ [Ringover](https://www.capterra.com/p/169627/RingOver/) has the second-highest rating on this list, 4.83, behind only OnSIP's 4.86 on 28 reviews, and it has the largest review base of the eight at 429. Reviewers also give it the top scores for ease of use (4.84) and functionality (4.74). Its audience is distinctive: 63% of reviewers are in France, over half are at companies with 1–50 employees, and the most common titles are commercial roles, CEOs, and managing directors. It is a strong fit if your team lives in a CRM: reviewers highlight automatic call logging and click-to-call with tools such as HubSpot, Pipedrive, and Salesforce. A large share of its reviews are written in French, so if your team works only in English, check language and support coverage. #### Trial/Free Version - Free Trial - Free Version #### Device Compatibilty **Why users like it:** - **Ease of use:** Mentioned in 182 of 429 reviews - **Customer support:** Mentioned in 101 of 429 reviews - **CRM integrations:** Mentioned in 80 of 429 reviews **Key features:** - **Cloud calling on any device:** Includes mobile, web, and desktop apps on the Smart plan. - **Call recording, monitoring, and whispering:** Gives managers tools to coach agents. - **CRM integrations:** Adds click-to-call and automatic call logging; the Advanced plan adds a power dialer and call campaigns. **Limitations to know:** - **App and call stability:** Bugs, lag, and dropped calls came up in 42 of 429 reviews. - **Plan gating:** Advanced features and integrations that need higher-priced plans or add-ons, and SMS billed separately, came up in 25 of 429 reviews. **What a verified Capterra reviewer says:** "Ringover is very easy to use on a daily basis. As a Customer Success Manager, I appreciate having calls, contact history and communication tools centralized in one place. The interface is intuitive and makes it easy to manage client conversations efficiently." Rayan Rahou, CSM, Eulerian, September 2026 **Bottom line:** _Plan for the mid-tier: Capterra lists Smart at $29 per user per month, Power at $54 for advanced analytics and coaching, and Advanced at $64 for the power dialer. One manager described the app as "very laggy sometimes" (Jesse Slayton, Manager, Minti Cowork and Conference, March 2025), so test the mobile app on your own network. With 429 reviews and a 4.83 rating, it is the best-validated pick for sales and support teams._ ## 6\. [Unitel Voice](https://www.capterra.com/p/172777/UniTel-Voice/): Best for budget-friendly small teams _Unitel Voice web portal showing auto attendant, ring groups, and call settings_ [Unitel Voice](https://www.capterra.com/p/172777/UniTel-Voice/) sits right at the 20-review threshold, so its 4.75 rating is the most volatile on this list. Every one of its 20 reviewers is at a company with 50 or fewer employees (9 with 1–10), and 5 are owners. Reviewers pick it for price and human support: it starts at $9.99 per month flat, the lowest paid starting price on this list, and 11 of 20 mention support in their pros. Choose it if you are a solo operator or a new business that needs a business number, an auto attendant, and fax without a big setup. #### Trial/Free Version - Free Trial - Free Version #### Device Compatibilty **Why users like it:** - **Easy setup and onboarding:** Mentioned in 10 of 20 reviews - **Price:** Mentioned in 7 of 20 reviews **Key features:** - **Auto attendant and IVR:** Greets callers and routes them by menu or business hours. - **Ring groups and virtual extensions:** Lets a small team share one business number. - **Online fax:** Includes faxing, which one reviewer said replaced a separate $100 annual fax service. **Limitations to know:** - **Setup friction:** Mentioned in 3 of 20 reviews, including one 1-star reviewer who expected a custom number that was not available. - **App and texting limits:** Mentioned in 2 of 20 reviews, so treat this as an early signal given the small sample. **What a verified Capterra reviewer says:** "The faxing ability will save me an additional $100 annual fee I currently pay to a stand alone fax service. So far, anytime I've had a question, Unitel's reps have been there to quickly answer and resolve any and all issues." Howard Goldson, Managing Director, Pinnacle Wealth Strategies, April 2026 **Bottom line:** _The trade-off is polish: one reviewer wrote that the "App interface and web login UI is not as smooth and modern as I would expect" (Will Jones, Communications and Outreach Director, Liliane Peal Studios, April 2026). The $9.99 Start-Up plan includes 1 number, 3 users, and a monthly minute cap, while Unlimited is $24.99, so budget for the higher tier if you take many calls, and compare it with Ringover in Capterra's_ [_Ringover vs. Unitel Voice comparison_](https://www.capterra.com/compare/169627-172777/RingOver-vs-UniTel-Voice)_. For a solo operator or new business, it offers the lowest starting price on this list, with an auto attendant and fax included._ ## 7\. [Wildix](https://www.capterra.com/p/218251/Wildix/): Best for partner-deployed unified communications _Wildix Collaboration app showing calls, chat, and video in one browser-based interface_ [Wildix](https://www.capterra.com/p/218251/Wildix/) has 205 reviews at 4.71, but it is unusual on this list: its reviewers are largely telecom and IT professionals who deploy it for customers rather than end users, 85 of 205 reviews come from Italy, and 93% are at companies with 11–200 employees. Reviews for Wildix in this dataset run through December 2025. It earns its place on flexibility and unified communications. Reviewers rate functionality 4.63 and support 4.60, but value for money is 4.18, the second-lowest on the list. If a managed service provider will configure it, it suits businesses that want voice, video, and chat in one platform. A very small business without IT support may find it heavier than it needs. #### Trial/Free Version - Free Trial - Free Version #### Device Compatibilty **Why users like it:** - **Features and flexibility:** Mentioned in 76 of 205 reviews - **Ease of use:** Mentioned in 59 of 205 reviews - **Voice, video, and chat together:** Mentioned in 50 of 205 reviews **Key features:** - **Unified calling, video, and chat:** Runs in a browser, desktop, and mobile apps. - **CRM integrations:** Adds click-to-call and call logging, with 200+ integrations listed by the vendor. - **Contact center options:** Includes queues, intelligent call distribution, and supervisor wallboards. **Limitations to know:** - **Pricing and licensing:** Mentioned in 43 of 205 reviews, and Wildix does not publish prices online. - **Hardware limits:** Mentioned in 42 of 205 reviews, including proprietary phones, headset compatibility, and devices available only for rent. **What a verified Capterra reviewer says:** "I love the sales intelligence feature on Wildix X-bees - being able to quickly search for different topics and find relevant information is a time-saver. Also the ease of use of the interface and being able to change devices seamlessly during calls are unbeatable compared to the competition." Faize Akçaba, Managing Partner, Foppex, November 2025 **Bottom line:** _A distributor and daily user put the pricing trade-off plainly: "Pricing can also be challenging for very small companies. In some cases, customers must buy full feature packages even when they only need a few items." (Väino Reintamm, General Manager, Esecom International OÜ, November 2025). Capterra lists no starting price because Wildix is sold through channel partners, so request a quote and compare it with Ringover in Capterra's_ [_Ringover vs. Wildix comparison_](https://www.capterra.com/compare/169627-218251/RingOver-vs-Wildix)_. For businesses with an IT partner, its 4.63 functionality rating makes it a flexible unified communications option._ ## 8\. [Zoom Phone](https://www.capterra.com/p/208535/Zoom-Phone/): Best for teams already on Zoom _Zoom Workplace app showing calls, voicemail, chat, and meetings in a single interface_ [Zoom Phone](https://www.capterra.com/p/208535/Zoom-Phone/) has 42 reviews at 4.36, the second-lowest overall rating on this list. Reviewers rate its ease of use 4.76, so the gap comes from what they find after setup. Half of its reviewers are at companies with 11–200 employees, and 23 of 42 are in the U.S. It is the natural pick if your team already uses Zoom Meetings, since calls, voicemail, messaging, and meetings share one app: 24 of 42 reviewers mention the Zoom integration or the single app. One reviewer noted a drawback of that design, that contacts without a Zoom account are harder to include. #### Trial/Free Version - Free Trial - Free Version #### Device Compatibilty **Why users like it:** - **Ease of use:** Mentioned in 19 of 42 reviews - **Call quality:** Mentioned in 13 of 42 reviews **Key features:** - **Call queues and auto attendants:** Routes inbound calls for busy teams. - **Call recording and voicemail transcription:** Supports documentation and follow-up. - **Unified calls, chat, and meetings:** Includes domestic SMS and MMS on U.S. and Canada plans. **Limitations to know:** - **Call quality and dropouts:** Mentioned in 12 of 42 reviews, usually tied to unstable internet. - **Add-on costs and plan limits:** Mentioned in 6 of 42 reviews, including international rates and features gated to higher plans, so confirm in a demo. **What a verified Capterra reviewer says:** "Zoom Phone has been a reliable and user-friendly business phone solution. The integration with the broader Zoom platform makes it easy to manage calls, voicemail, messaging, and meetings from a single interface. Call quality is consistently strong, and features such as call queues, auto attendants, call recording, and voicemail transcription help improve efficiency in a busy customer service environment. The administrative tools are straightforward, making it easy to manage users and phone settings across teams." Nigel Dalziel, CCO, OC Transpo, September 2026 **Bottom line:** _Not every reviewer agrees on reliability: one wrote "Zoom Phone is missing faxing capabilities. Occasionally, experience dropped calls and poor audio quality." (Kristl Kephart, Sr Customer Service Rep, Mercer Health and benefits LLc, February 2026). Capterra lists U.S. and Canada Metered at $10 per user per month, Unlimited at $15, and Global Select at $20, and you can compare it with RingEX in Capterra's_ [_Zoom Phone vs. RingEX comparison_](https://www.capterra.com/compare/208535-242188/Zoom-Phone-vs-RingCentral-MVP)_. For teams already on Zoom, its 4.76 ease-of-use score makes it the natural add-on._ ## What should small businesses look for in VoIP software? In my view, picking VoIP software for small business comes down to more than a feature checklist. Here are the 5 factors that decided fit across the 1,021 reviews I read. For a wider look at the category, see Capterra's [business phone systems software](https://www.capterra.com/business-phone-systems-software/) picks and the [telephony software](https://www.capterra.com/telephony-software/) category. | Factor | What reviewers reported | What to test in a trial | | --- | --- | --- | | Setup without IT help | Ease of use was the top pro theme across the dataset. Learning curves came up mainly for Wildix (21 of 205 reviews), which is built for partner deployment, and for setup at Unitel Voice. | Run a trial with your own numbers and devices, not the vendor's demo. | | Call quality on your internet | Call quality and connection problems were the most common complaint across the full 5,935-review export (780 of 5,917 reviews with cons text); Zoom Phone, Google Voice, Ringover, and RingEX reviewers all mention lag or dropped calls. | Test on your office Wi-Fi and on a mobile connection. | | Support when something breaks | OnSIP reviewers rate support 4.96 and Unitel Voice 4.80, while RingEX is 4.04. | Call support during the trial and note how long a person takes to answer. | | Pricing and what the entry price leaves out | Several tools gate features by plan: Ringover's advanced analytics start at its $54 Power plan and its power dialer at $64, RingEX adds auto call recording and internet fax at Advanced, and some reviewers found SMS billed as an add-on. | Confirm per-user versus flat pricing, minute caps, and what each tier includes. | | Fit with team size and calling style | 800.com or Google Voice is plenty for a solo operator; OnSIP, Ringover, RingEX, and Zoom Phone suit shared team calling; Wildix suits partner-managed unified communications. | If your team makes high volumes of outbound calls, check Capterra's [call center software](https://www.capterra.com/call-center-software/) category. | In my analysis, plan gating was the pricing trap I flagged most often, so ask every vendor for the full per-user cost with the features you need before you compare quotes. Ask about number porting Setup and number porting came up in 70 of 241 800.com reviews. Ask every vendor how long porting your existing number takes and whether it costs extra. ## Which VoIP software should you choose? Here is how I would match each situation to a pick, based on who actually reviews each product. | Buyer profile | Best fit | Why | | --- | --- | --- | | Solo operator or very small practice that needs a second line | Google Voice | Only pick with a free version; 15 of 32 reviewers are at companies with 1–10 employees. | | Small business that mainly needs toll-free or vanity numbers | 800.com | 76% of 241 reviewers are at companies with 1–50 employees; rated 4.79 for ease of use. | | Small office or nonprofit that wants a person on the phone | OnSIP | Support score of 4.96; 24 of 28 reviewers mention support in their pros. | | Sales or support team that lives in a CRM | Ringover | CRM integrations came up in 80 of 429 reviews, and it holds a 4.83 rating. | | New or solo business on a tight budget | Unitel Voice | $9.99 flat starting price, the lowest on the list, with online fax included. | | Team already using Zoom Meetings | Zoom Phone | 24 of 42 reviewers cite the Zoom integration or the single app. | | Larger team that wants mobile calling, texting, and fax | RingEX | 9 of 24 reviewers are at companies with 201–500 employees; includes SMS, MMS, and internet fax. | | Business with an IT partner that wants voice, video, and chat together | Wildix | Functionality rated 4.63; 50 of 205 reviews cite voice, video, and chat in one platform. | In my analysis, the best VoIP software for small business is rarely the one with the longest feature list. The reviewers who sound happiest picked for support and call quality first, then confirmed both in a trial on their own network and devices. You now have eight reviewed options and a way to match them to your team, so the next step is comparing pricing, features, and verified reviews side by side. ## Frequently asked questions about VoIP software What is VoIP software? VoIP (voice over internet protocol) software lets you make and receive phone calls over the internet instead of traditional phone lines, using apps on computers, smartphones, and desk phones. It typically bundles voicemail, call routing, call recording, and texting. See Capterra's full [VoIP software](https://www.capterra.com/voip-software/) category. What is the best VoIP software? There is no single best VoIP software for every business. OnSIP has the highest rating at 4.86 but on only 28 reviews, Ringover is the best validated with 429 reviews at 4.83, and 800.com suits small teams that need toll-free numbers at 4.76 across 241 reviews. How much does VoIP software cost? Pricing in this list ranges from $9.99 per month flat for Unitel Voice's Start-Up plan to $30 per user per month for RingEX's Core plan. Google Voice starts at $10 per user per month, OnSIP at $18.95 per user per month, 800.com at $23 per month flat, and Ringover at $29 per user per month, while Wildix and Zoom phone are sold on a custom quote. Actual costs depend on the product and subscription plan you choose. What features should I look for? The features reviewers mention most are call routing, voicemail, call recording, CRM integrations, and mobile and desktop apps. Prioritize the ones tied to how your team actually takes calls. Is there free VoIP software? Google Voice is the only pick here with a free version, which reviewers describe as enough for a basic second line. Browse Capterra's list of [free VoIP software](https://www.capterra.com/voip-software/s/free/). None of the other seven picks is confirmed free in this dataset, so check each vendor's current plans and trials. Who should skip a full VoIP system? Solo operators who only need a second number and voicemail can start with Google Voice or an entry plan such as Unitel Voice's $9.99 Start-Up plan, then move to a full system as headcount and call volume grow. Is Ringover or RingEX better for small teams? In the same review export, Ringover scored 4.83 across 429 reviews and RingEX scored 4.33 across 24 reviews, so Ringover is far better validated, though RingEX's sample is small.

All ratings and review counts reflect data as of the time of publication. Pricing was verified against each product's official Capterra listing in October 2026. To be included in this list, each product had to: 1. Appear on Capterra Shortlist for VoIP software (2026). 1. Have a minimum of 20 verified Capterra reviews in the last 24 months. 1. Have an overall rating of 4.2 or above based on reviews in the last 24 months. Several products were evaluated and excluded. Meeting tools (Microsoft Teams, Zoom Workplace, Google Meet, Webex Suite, Zoho Meeting, GoTo Meeting) were excluded because they are not on Capterra Shortlist for VoIP software, even though they make up 48% of the raw review pull. Shortlist products below the 4.2 rating floor were Aircall (3.74), Dialpad (3.63), Nextiva (3.13), Twilio (3.80), 3CX (4.11), RingCX (4.17), Five9 (4.12), Zoho Voice (4.07), and Genesys Cloud CX (3.86). CallTools, Ooma Office, JustCall, and GoTo Connect did not reach 20 reviews in the dataset. Convoso, Weave, Bitrix24, and Emitrr met the rating and review thresholds but were set aside because they are an outbound contact-center dialer, a customer-engagement platform, a CRM suite, and a text-messaging tool rather than general business phone systems. To build the shortlist: - I analyzed 1,021 verified Capterra reviews of 8 products, drawn from a VoIP review export of 5,935 reviews across 159 products before the exclusions above. - Reviews were assessed on overall rating, ease of use, functionality, value, and support, and on themes in the pros and cons text. Theme counts reflect keyword matches in review text and are directional. - Quotes are verbatim from the review dataset, and some excerpt consecutive sentences from a longer review field. Non-English reviews were not quoted. - Pricing was verified against each vendor's official Capterra listing at time of writing. **Editorial independence:** Products are selected and ranked based on an objective methodology. While some vendors may pay Capterra when they receive web traffic or leads, this does not influence our selection or analysis.
