7 Best VoIP Providers in 2025: My Honest Review

Gone are the days when traditional phone calls were the medium of communication. Most businesses bank on VoIP providers to optimize growth.

As a sales associate in my early professional days, I've gathered hands-on experience working with VoIP providers. I also personally believe it to be the most effective sales channel.

I had my fair share of challenges with VoIP providers that eventually led to missed sales deals. Sometimes, the inbound contact data wasn't stored, and other times, there were long waiting lines, latency issues, jitters, or call disconnections.

Even today, sales development representatives (SDRs) encounter the same issue as businesses fail to invest in a compatible VoIP provider that employees can use remotely, integrate with CRM, convert recordings to voicemail, and keep minimal latency and call disturbance. 

To determine the best VoIP options for creating uninterrupted sales calls, I experimented with the 7 best VoIP providers in 2025. 

While evaluating a VoIP service, many extra hardware requirements and investments must be checked and sorted. 

Sure, VoIP is a cloud-based telephone exchange service that offers firms a cloud-calling infrastructure, but it comes with additional hardware requirements and hidden costs.

7 best VoIP providers I strongly recommend 

When I was in sales, I was not part of the decision-making team that shortlisted, tried, and broke down software functionalities. But even though I didn't play a part in shortlisting a VoIP provider, I was part of the outbound sales team that explored and used it.

By summarizing my experience of 2 years working with these cloud telephone exchange software, I can say that an ideal VoIP system should offer extensions to a remote workforce, integrate with CRM, and stay compatible as the business expands. 

What makes a VoIP provider worth it: my honest take

As an erstwhile sales professional, I'd say that jitter-free, clear, high-quality audio exchange with VoIP software is crucial to call center teams.

But, as a business looking to gather intel, you need to factor in contract value, trial periods, configuration cost, hardware requirements (like IP phones and adapters), and UI/UX compatibility to integrate it with your existing call center stack.

According to a Precient and Strategic Intelligence report, VoIP software market revenue is predicted to grow to $30,441.5 million by 2025, at a CAGR of 13.4% between 2020 and 2025, highlighting growing investment in the call automation sector.

To help you choose wisely, I've listed down a few important parameters to check while evaluating a VoIP system:

• Call quality and reliability: I shortlisted the providers that offered seamless call connectivity and high-resolution audio management. If the call quality isn't clear, the rest doesn't matter. I looked for providers that offered high definition (HD) voice, minimal jitter and latency, and a robust uptime service level agreement (SLA) along with a user-friendly interface. A solid VoIP system should be built on existing data centers and have automatic failover in place.
• Integration capabilities: I always checked whether the VoIP system integrates with my existing tools like CRM platforms (Salesforce or HubSpot, among others), helpdesk software, ticketing tools, etc. This saves time, avoids data silos, and streamlines the agent workflow.
• Scalability and multi-location support: I also looked for scalable and flexible solutions for growing companies. Whether it is a 10-person team or a 100-seat call center, I need a solution that scales effortlessly. I also looked for tools that offer services like remote agents and multiple office locations and have features like dynamic call routing or virtual extensions. 
• Security and Compliance: Security cannot be compromised at any stage. I checked for VoIP tools adhering to proper standards like GDPR, HIPAA, or PCI-DSS. A good VoIP provider should have end-to-end call encryption and data privacy monitoring to ensure your data exchanges are safe from malware.
• Total cost of ownership (TCO): I also scrutinized the entire cost of the VoIP system, including additional charges, configuration costs, setup costs, and so on. I also factored in international calling rates, roaming, add-on features, and support charges. A low-cost plan isn't cheap if you pay extra for every useful feature.
• Support and service level agreements (SLAs): I also ensured that these solutions offer 24x7 live support (not just a chatbot), a clear SLA, and a responsive customer service team. Fast, knowledgeable support is non-negotiable in a call center environment.
• Cost-effectiveness and ROI: I also shortlisted VoIP providers that offer detailed trials and demos of the tool. A cost-effective solution isn't always the cheapest but a tool that gives a return on investment. I tried tools that balance price with performance, features, and future scalability. I looked for transparent pricing models, bundled features (like auto-dialers or call analytics), and flexible plans that help grow the business. 

True to my analysis, these VoIP solutions offer consistent call quality, encryption, global functionality, minimum disruptions, clarity, and cost-effectiveness. 

Out of the 40+ VoIP systems that I initially set out to evaluate, I shortlisted the top 7 VoIP systems that you can implement with a softphone or a VoIP phone.

This list below contains genuine reviews from the VoIP providers category page. To be included in this category, software must,

• Provide VoIP PBX systems for businesses and/or offer a VoIP softphone application.
• Offer necessary hardware, should a solution require it
• Include features that assist in regulating incoming calls. 

*This data was pulled from G2 in 2025. Some reviews may have been edited for clarity.

1. Nextiva: Best for phone features with modern automation

Nextiva is an AI-based cloud telephony and customer experience tool that offers businesses services like call transcription, call recording, call-to-voicemail, and cloud data storage to organize their outbound lead workflows.

As a category leader on G2, Nextiva has a customer satisfaction score of 91 in the overall business segment, with 89% of G2 users that will likely recommend it for phone calls, AI voice assistance and direct VoIP calls.

When I first started looking for a reliable VoIP solution, I had no idea how many options were out there. However, after doing my own comparisons, I landed on Nextiva, which has been the best decision for my business.

What impressed me was the clear and consistent call quality, even when working remotely or juggling multiple conversations at once. The voice clarity was on another level compared to what I'd experienced with previous providers. It made our day-to-day operations, from calls to client coordination, feel more professional and less stressful.

I immediately noticed how robust and reliable their VoIP platform is. It offers real-time call routing, built-in texting options, and even voicemail-to-email, which has saved me more time than I can count. 

The little things, like not missing an important message because it's waiting in your inbox with a transcription, make a big difference. We also started using their contact center software, part of the VoIP system, which completely transformed how we interact with our clients. Features like detailed call analytics and intelligent routing helped us respond quickly and stay on top of everything.

I also want to highlight their customer service philosophy. I've dealt with tech vendors before, and usually, it is a nightmare due to long hold times, robotic answers, and unhelpful reps. Not here. Every time we had an issue, we got through to someone from the customer service team within minutes.

That said, Sure, Nextiva has its set of downsides. There is room for improvement, especially in user autonomy and third-party integrations. I struggled a bit with the chatbot functionality, as I got delayed answers for my queries. At some times, the AI agent was not available on the chat, which caused delays.

Overall, Nextiva is a powerful and reliable VoIP solution that optimizes outbound and inbound calling and offers detailed calling reports. This allows us to automate our growth and build a hassle-free client experience. 

What I dislike about Nextiva:

• While Nextiva is great, the system, unfortunately, dropped my calls several times, and then, when my call was picked up by a human, I dropped again without a follow-up call to reconnect, as also echoed in G2 reviews.
• After a cellphone update, I noticed the app faced some temporary performance issues. These were frustrating at times, though they seem consistent with feedback from other G2 users and may improve with future updates.

What do G2 users dislike about Nextiva:

"The automated phone system dropped my call so many times, and then when my call was picked up by a human, I was dropped again without a follow-up phone call to reconnect. That was a point of contention. The availability of customer service and tech support via phone could be better."

- Nextiva Review, Rahab B.

2. OpenPhone: Best for smart call recording and virtual number management

OpenPhone is a private, reliable VoIP provider that integrates calls, texts, and messages into one app to better serve consumers. It also offers AI-powered transcription to summarize calls, extract crucial data, and integrate with CRM.

Based on 2000+ reviews, OpenPhone is a category leader with a near perfect customer satisfaction score of 99, with 95% users recommending it for VoIP number, instant messaging and phone conferencing.

The OpenPhone interface really stood out to me. It was clean and intuitive and worked just as well on the desktop as it did on mobile, which is huge for me because I am bouncing between devices all day. I can add client info, set custom voicemail greetings, and seamlessly switch between different numbers in the app.

It also includes team-wide shared inboxes, so no matter who responds, the whole team stays in the loop. We'd even set up roles and permissions for better call routing, which is especially handy for managing support vs. sales calls.

The call quality has been consistently solid, and I love how it lets me record calls, which is perfect when I'm juggling multiple conversations and want to circle back later. 

One of my favorite features is the AI-powered call summaries. They save me from typing out notes and help me stay on top of follow-ups. I've also started leaning more toward integration. OpenPhone integrates with Slack, HubSpot, and even Zapier, which opens endless workflow automation possibilities. For instance, I have set up automatic notifications for missed calls or voicemails in Slack, which helps our teams gather data even when we are not in the app.

The pricing is surprisingly fair, especially considering the availability of features like call recording, voicemail transcription, custom business hours, and contact syncing in the subscription tiers. OpenPhone's premium plans are generous, especially the standard and premium tiers. These plans include integrations, auto-replies, snippets, analytics, and multi-number support.

However, no app is perfect, and OpenPhone does have its drawbacks. I've run into a few quirks, like the app occasionally ignoring my phone's "Do Not Disturb" setting or the lack of custom ringtones (minor issue, but still).

One of my teammates mentioned that the management monitoring features could be more intuitive, and we struggled to properly set private and shared access. Other teammates pointed out that while the voicemail and call transcription generally work great, there are times when messages don't appear immediately.

And if you rely heavily on international texting or receiving messages from banks or financial services (like PayPal), there might be limitations, likely due to how OpenPhone handles shortcodes and carrier partnerships.

That being said, OpenPhone is one of the most agile and reliable solutions to offer a high-speed call network, store inbound data, and route active calls to the right person while providing customer-centric features to a business. 

What I dislike about OpenPhone

• Calls are generally clear, though there can occasionally be a slight delay that leads to people speaking over one another—a minor issue also noted in some G2 reviews.
• The platform covers most core needs well, though more advanced customization for workflows and automation would be a welcome addition. This has been mentioned by other G2 reviewers as well. 

What do G2 users dislike about OpenPhone

"We like just about everything with OpenPhone. The only thing I have found confusing is the automated texting when a phone call goes unanswered. I had a hard time turning it off. We also had an issue with the AI voicemail message not being able to handle Spanish. The English, though, was great. Spanish gave us a good laugh but didn't sound very professional."

- OpenPhone Review, Vera B.

3. Webex Calling: Best for browser-based calling and conference integration

Webex Calling is a reliable VoIP tool that offers PBX infrastructure for companies so that they can manage incoming calls without switching to another telephone exchange network. It also stores your call details, offers transcription, and more. 

Based on 451 reviews, Webex Calling has recieved a customer satisfaction score of 76, with 91% of users likely to recommend it for PBX, call center integration and video conference integration.

What stood out about Webex calling was how easy it is to set up. It offers a user-friendly, easy-to-navigate, and intuitive dashboard, even for non-tech-savvy users.

The whole process, including number provisioning and user assignments, took me less than an hour.

One of the strongest aspects of Webex Calling is the high-quality audio and video. Seriously, the high-definition (HD) calling and noise cancellation features make a noticeable difference, especially during longer meetings or international calls.

Call quality stays consistent even when bandwidth dips slightly, though like any VoIP service, it still occasionally struggles under poor internet conditions. On a good connection, you get crystal-clear conversations with barely any latency.

The platform is designed around a centralized cloud PBX system that seamlessly manages calls, extensions, and voicemail. I can hop between my desk phone, mobile app, and desktop client without missing a beat. It also forwards the calls automatically and integrates voicemails with emails and transcriptions.

The platform supports advanced features like call queuing, hunt groups, shared lines, and even location-based routing. If you are in a larger organization, you can benefit a lot from this flexibility. 

There is also a lot of attention to the mobile and desktop app experience. The UI is sleek and responsive. Features like one-click meeting scheduling, integration with Outlook and Google Calendar, and real-time collaboration (screen-sharing, whiteboarding, and in-call chat) eliminate the need for multiple platforms.

In fact, Webex Calling blends with the full Cisco Webex Suite. So, if you are already using Webex Meetings or Webex Teams, the calling functionality is an existing part of the workflow.

However, this platform also has a few drawbacks. I felt that there was a learning curve, especially when configuring advanced features or setting up auto attendants for multiple locations.

Also, while the base experience is smooth, many of the more powerful admin tools and analytics are only accessible in the premium plans. The pricing, too, is a bit on the higher side, particularly for small businesses and startups. You get what you pay for, but it's definitely an investment, especially for businesses with a tight budget.

Even though the free version is generous with features like 50-minute meetings and basic calling, this doesn't work for established businesses. You might want to look at the paid tiers if you are scaling your business. The enterprise tier package offers features like call recording, call park/pickup, call analytics, and integration with CRM platforms.

Overall, Webex Calling is a reliable Cisco tool that provides some reliability, uses TLS/SRTP encryption to protect calls, and seamlessly manages cloud call operations.

What I dislike about Webex Calling:

• Webex Calling is typically reliable with a smooth calling experience, though on rare occasions I faced difficulty registering on Webex Cloud for extended periods. Similar experiences have been mentioned in G2 reviews.
• The admin portal works well for core needs, though it could benefit from additional customization options—such as more flexibility in user permissions and call flow configurations. This has also been highlighted by other G2 users.

What do G2 users dislike about Webex Calling:

"It has a dependency on PSTN or ISDN. If you want to reroute your calls from an SIP trunk, you need to deploy an on-site device that can handle the traffic from an SIP trunk. It would be cool to integrate with vendors other than Cisco for SBC solutions or API integration to handle this kind of traffic."

- Webex Calling Review, Gerardo H.

4. RingEx: Best for team collaboration with screen sharing

RingEx is an advanced phone and call analytics solution that helps initiate 15-20 calls a day, generate GPT-powered call summaries, and optimize the calling workflow for employees with advanced AI/ML feature integrations.

Based on 665 G2 reviews, RingEx has recieved a high customer satisfaction score of 93%, with 80% G2 users likely recommending it for call management, PBX systems, VoIP smartphone, and integrations.

The AI functionality of RingEx is simply awesome. It is not just some gimmick; it helps with documenting calls, summarizing voicemails, and nudging me when I am drifting from the call script. It's almost as if I have a quiet and efficient call assistant in the background.

I also want to highlight the flexibility RingEx offers. Once you set the VoIP, you can make or receive calls from your desk phone, mobile app, or even a softphone on your laptop and switch between them.

Features like "call flip" and the seamless handoff across devices make remote work feel less fragmented. When I'm on the move, the mobile app comes to my rescue. It is responsive and doesn't feel like a watered-down version of the desktop experience. 

On the admin side, the admin portal makes it easy to manage users and tweak call routing routes. Even our IT team, who are typically buried in complexity, has said that the backend is refreshingly straightforward. The dashboard gives us real-time call analytics, which has made tracking KPIs and agent performance much easier.

The platform also has a few drawbacks. While the AI features are helpful, they can sometimes feel a little limiting. Call transcriptions sometimes misinterpret different call accents or jargon. Also, voicemail delays can be annoying. Sometimes, I am waiting way too long for a voice message to appear in the system.

Reporting is another area where the tool can improve. Some users on my team have flagged that the reports aren't always accurate or up to date, which can throw off our weekly reviews.

There is also some friction when it comes to integrations. I really wish RingEx could play nicer with tools like Cinic or certain CRMs without the clunky wait-around. And yes, the platform sometimes feels permission-heavy. I can't always edit phrases or responses in the AI settings because of admin-level restrictions that don't make sense in day-to-day use.

Further, the premium and advanced tiers unlock features like multi-level IVRs, advanced call analytics, and integration with third-party CRMs and productivity tools. But if you're operating the free version, you might feel a bit limited.

Overall, RingEx offers advanced calling features, voicemail to email, call recording, and advanced call analytics to set robust calling protocols and maintain a smooth contact center infrastructure network. 

What I dislike about RingEx

• RingEx provides a strong and feature-rich platform, though the mobile app can occasionally feel slow or freeze when entering contact information—an issue some G2 users have also noted.
• Getting started with RingEx took a bit of exploration, especially when customizing it to fit my needs, but once set up, it became much easier to navigate. Similar experiences are reflected in G2 reviews. 

What do G2 users dislike about RingEx

"It sometimes takes a while to get hold of customer support when you need them. Also, occasionally, messages come through a bit late, but it's not a deal breaker. The basic plan is a bit limiting. We had to upgrade to get more people in our video calls, which wasn't mentioned clearly upfront. And while the AI notetaking is great, sometimes it misses important points when multiple people are talking at once."

- RingEx Review, BP R. 

5. Dialpad Connect: Best for intelligent calling with prospect data logging

Dialpad Connect is a reliable telephony platform that offers video conferencing abilities, messaging, call connectivity, and voicemail services to enterprises with minimal hardware requirements. It also offers AI-based functionality to facilitate interactions and maintain call repositories. 

Based on 1281 verified G2 reviews, Dialpad has recieved a customer satisfaction score of 71, with around 87% of G2 users likely recommending it to other software buyers for video conferencing, VoIP number, and desk-to-desk calls. 

I've been using Dialpad Connect for a while now, and I have to say, it nails a lot of what I look for in a modern business phone system. The first thing that really stood out to me was the cross-platform experience across devices. Whether I am using the mobile app, the desktop app, or even the desk phone, everything feels connected and consistent.

I can start a call on my computer, move it to my phone, and transfer it to a colleague without missing a beat. The cross-device sync makes a huge difference, especially when you are constantly on the move and switching between setups.

I also loved how easy it is to use. Setting up new users, making calls, and sending messages were never this easy and well-managed. The UI is clean and intuitive, and the call quality is almost crystal clear.

I've rarely had a dropped call or a poor connection. It also offered AI-powered call features like real-time transcription and voicemail-to-text. I don't always have time to listen to voicemails or scribble notes during meetings, so getting accurate call summaries and searchable call transcripts really saved the day for me.

I've tried the Standard and Pro plans, and the difference between them is pretty clear. The standard plan is solid if you are running a small team and just need basic calling, messaging, and integrations like Google Workspace or Microsoft 365.

However, the Pro plan offers features like CRM integrations (Salesforce, HubSpot or Zoho), local number support in over 70 countries, and advanced analytics dashboards.

I also appreciated the ability to create custom call routing rules and use API to automate our workflow. If you work with a distributed team or handle a high call volume, upgrading to Pro is definitely worth it.

However, Dialpad does have its imperfections. One of the most frustrating experiences was onboarding new employees. The admin interface, especially when it comes to configuring permissions or assigning numbers, can feel clunky.

There were a few times I had to dig through help articles just to figure out how to assign a number or set up a voicemail for someone new. Their knowledge base is extensive, but the way it is organized is not beginner-friendly. Also, I've run into a few quirks with call notifications, like calls only ringing on my desktop and not my phone or vice versa.

I also felt the SMS feature could be improved. Some of my team members mentioned outbound SMS not being activated for weeks, especially depending on the region and plan. Provisioning for messaging isn't smooth and can lead to miscommunication.

Overall, Dialpad Connect is one of the most credible VoIP platforms for initiating and directing calls, assigning them to a rep, and providing real-time transcription to users. 

What I dislike about Dialpad Connect 

• Dialpad Connect works seamlessly across multiple devices, though on occasion calls may ring through to connected cell phones without the ability to answer—an issue also noted by some G2 users.
• Call quality is generally reliable, though there have been rare instances where calls briefly stopped working. This has also been mentioned in G2 reviews.

What do G2 users dislike about Dialpad Connect

"It's AI, so of course it has its flaws -- some of the words are mistranslated, and the transcription can be messy, but I still find it easy to follow along."

- Dialpad Connect Review, Kaylin W.

6. Vonage Business Communication: Best for customization and voicemail

Vonage Business Communication is a unified interaction platform that allows businesses to interact with their customers via calls, messages, emails, voice, and video. It also offers 99.99% uptime and syncs with any compatible device to retrieve data.

As a category leader on G2, Vonage Business Communication has recieved a customer satisfaction score of 68 and market presence score of 79, with 86% of G2 users likely recommending it to other software buyers across small, mid and enterprise segments.

The interface of Vonage Business Communication is modern, user-friendly, and surprisingly flexible, whether I'm on the desktop or mobile. Vonage isn't just about voice calls, though I'll say the quality is mostly solid. It also lets me text clients (which I do often), schedule video meetings, and even record calls for reference.

There is a certain convenience to having all these communication tools rolled into one app. It integrates with CRMs and applicant tracking systems (ATS) like Bullhorn, which is a big plus in my recruiting work. I have also used its Microsoft Teams integration, as it is smooth and saves me from switching tabs every time.

I really like the ability to set up user groups and generate team-wise reports. It helps when I want to break down performance across departments or keep tabs on call volumes. I also want to highlight their voicemail-to-email transcription. I can glance at voicemails without needing to hit play, which is great when I am swamped with work or on the move. 

I want to discuss a few downsides as well. I did struggle with call connectivity, especially with mobile. Sometimes, calls drop randomly, or the app just lags. There have been a few cases where I got a missed call notification way after the call came in, which obviously isn't ideal when trying to close a deal.

I've also had messages not go through, particularly to certain carrier numbers. It's not frequent, but it is a little annoying when it happens. Thankfully, Vonage support is actually responsive. I contacted them a couple of times, and they got back to me quickly with useful fixes. 

The platform offers various subscription tiers, but what's cool is that even on the basic plan, you get access to features like unlimited calling and texting in the US, spam call protection, and app access across devices. As you move up to premium or advanced tiers, you unlock features like CRM integration, on-demand call recording, call group analytics, and even AI-powered features like speech analytics or smart call recording.

Overall, Vonage Business Communication is an agile network service provider that integrates with your existing enterprise resource planning system (ERP) and organizes a centralized database for inbound calls, messages, and texts. 

What I dislike about Vonage Business Communication:

• Call connectivity is generally strong, though on rare occasions, I experienced dropped calls due to technical glitches—something also mentioned in G2 reviews.
• Call quality is usually clear, though at times the audio can sound choppy, making conversations a bit harder to follow. This has also been discussed in G2 reviews.

What do G2 users dislike about Vonage Business Communication

"In Vonage Business Communication, a call is often dropped due to a technical glitch. Sometimes when more than 2 employees talk with each other, then there is an echo of the audio in the call."

- Vonage Business Communication Review, Avi S. 

7. GoTo Connect: Best for scalable phone systems with attendants

GoTo Connect helps you initiate calls from either a VoIP phone, an IP phone, a cell phone, or a softphone and provides the flexibility of tracking call conversations, providing transcriptions, or offering real-time call routing to manage clients wisely.

What I loved about GoTo Connect is the simplicity of the platform. I didn't need an IT expert to onboard my team. The interface is clean and intuitive.

GoTo Connect has recieved a customer satisfaction score of 98 on G2, with 92% of users rating it as 4 on 5 stars, and 89% users likely recommending it for Virtual PBX, desk to desk calls and VoIP number.

One of my favorite features is the Dial Plan Editor. It gives me so much flexibility to route calls exactly how I want. Whether I am setting up custom workflows for different departments or managing after-hours routing, this Dial Plan Editor offers the options.

I also loved the inclusion of the mobile app. I can seamlessly switch from my desk phone to my cell phone, which is awesome for days when I am bouncing between meetings or working remotely. Plus, the call quality has been solid for the most part. There were no instances of dropped calls and no dip in sound quality, regardless of whether I was on my desk or not.

I also appreciate how user-friendly everything is. A few of my colleagues aren't that tech-savvy, but even they had no problem adapting to it.

Also, the customer service was great and responsive. I've had some genuinely helpful interactions with support when I ran into issues. But it was a little hit-and-miss. Sometimes, especially when dealing with billing or porting numbers from other carriers or network operators, support can feel slow and unresponsive.

One of the things I didn't realize until I got deeper into the platform was how different the experience is depending on the plan tier. I started with a more basic setup, but once I upgraded to the Standard plan, the range of features really opened up. The base tier gives you essentials like voice, video, and call recording, as well as integrations with platforms like Salesforce or Microsoft Teams. 

For example, with a premium tier, I could use real-time dashboards and historical reporting to track call performance, which would be really helpful if we were managing a remote team.

Further, the desktop app isn't perfect. I have had issues with it crashing or freezing randomly, and logging in through the web portal has failed a few times. And while the phone system hardware has great support, updates can sometimes cause minor disruptions.

Overall, GoTo Connect is a robust VoIP provider that optimizes your customer service workflows and provides seamless calling integrations to manage and improve call performance and efficiency.

What I dislike about GoTo Connect:

• The software generally works well, though I did encounter occasional glitches that led to missed calls—a point also mentioned by some G2 reviewers
• The desktop application usually performs as expected, though at times it feels a bit slow and requires a refresh to update data accurately. This is something other G2 users have also highlighted.. 

What do G2 users dislike about GoTo Connect:

"The only dislike is customers sometimes say the call in dropping in and out sometimes. Getting only part of the conversation can be frustrating at times. Possibly due to being an internet phone service. This can happen on my mobile or desktop phone, if this could be fixed then the service is perfect."

- GoTo Connect Review, Keith F.
