3. Dialpad Connect – Best cloud phone system for customer services teams
4. GoTo Connect – Best cloud phone system for unifying internal communications
5. 8×8 Work – Best for 24/7 customer support

Please note — in this guide, I’ll be recommending specific plans belonging to each provider.

1. RingCentral RingEX: Best Overall Cloud Phone System

• Entry-level plan: Core plan ($20 per user, per month)
• Tech.co recommends: Advanced plan ($25 per user, per month)

RingCentral RingEX is the best cloud phone provider on the market. It provides excellent call management features, including automated call screening, which 8×8 Work lacks.

Other standout features include a dedicated AI assistant, which takes notes in real-time, captures actions, transcribes calls, and more. This will help your employees to plan next steps, follow up with potential leads, and ultimately secure new business.

What do we like about RingCentral RingEX?

During our research process, the team was particularly impressed with RingCentral RingEX’s huge selection of features for managing both inbound and outbound calls, as well as its vast array of alternative communication channels.

Users can choose from phone, email, chat, SMS, and even e-fax, centralizing all your communications into one platform. What’s more, you can switch from phone call to video with one click, which is really useful for sharing content with a client.

RingCentral RingEX offers more than 300 third-party integrations, and from the Advanced plan ($25 per user, per month), you can get your hands on several CRM tools, including Salesforce and Zendesk.

Used together, VoIP and CRM centralizes your customer information and call records into one interface, meaning that you don’t need to switch between platforms, and you won’t lose track of any relevant data.

Additionally, we found RingCentral RingEX Advanced offers plenty of training tools, including call whisper and call recording, which allowed us to effectively keep track of how our calls were going in real-time. Dialpad Connect doesn’t offer whisper on any of its plans.

What limitations does RingCentral RingEX have?

While RingCentral RingEX is strong across the board, it doesn’t offer the same variety of hardware integrations as some of its contemporaries, including GoTo Connect and Zoom Phone.

However, with many businesses transitioning to softphones in 2026, this is a relatively minor complaint.

How much does RingCentral RingEX cost?

Below, you’ll find a breakdown of RingCentral RingEX’s pricing plans.

• Core: $20 per user, per month
• Advanced: $25 per user, per month
• Ultra: $35 per user, per month

RingCentral also has several available add-ons, which you can learn about below.

• RingCX AI Contact Center: $65 per user, per month
• RingCentral Events: $99 per organizer, per month
• RingCentral Rooms: $39 per room, per month
• Push to Talk: $5 per user, per month

2. Zoom Phone: Easiest Cloud Phone System to Use

• Entry-level plan: US & CA Metered plan ($10 per user, per month)
• Tech.co recommends: US & CA Unlimited ($15 per user, per month)

Zoom Phone is the easiest to use cloud phone system around. It is clearly laid out, with excellent site mapping for ease of navigation. We loved testing Zoom, with one individual from our testing group labelling the interface “quite calming.”

What do we like about Zoom Phone?

Zoom Phone is a highly affordable, streamlined VoIP platform with a shallow learning curve that will suit first-time users and price-conscious small businesses.

Despite its modest price point, the US & CA Unlimited Plan ($15 per user, per month) rivals RingCentral RingEX’s call management features, with call monitoring, automatic screening, and call barge all included.

Zoom is famous for its flagship video conferencing tool, and you’ll get access to it if you sign up to the Pro Plus plan ($18.33 per user, per month). This will appeal to B2B sales businesses, in which it is common to correspond with your leads over video call, as you progress down the sales funnel.

With its robust call management features, Zoom Phone is a great option for businesses that process a high volume of inbound and outbound calls — and want to keep an eye on spiraling overheads in 2026.

What limitations does Zoom Phone have?

The main drawback of Zoom Phone is its limited range of software integrations. It has far fewer CRM and helpdesk integrations than RingCentral, so if your business is expected to scale in the near-future, I would not recommend this provider.

How much does Zoom Phone cost?

Here, you’ll find a breakdown of Zoom Phone’s pricing plans. Our standout pick is the US & CA Unlimited plan ($15 per user, per month), which is easy to use, cheap, and has some great call management tools and security credentials.

• US & CA Metered: $10 per user, per month
• US & CA Unlimited: $15 per user, per month
• Pro Plus: $18.33 per user, per month
• Business Plus: $22.49 per user, per month
• Global Select: $20 per user, per month

Zoom Phone also has a few available add-ons, which you can learn about below.

• Zoom Phone Power Pack: $25 per month
• Additional phone numbers: $5 per month
• International calling: $10 per month

3. Dialpad Connect: Best Cloud Phone System for Customer Services Teams

• Entry-level plan: Standard plan ($15 per user, per month)
• Tech.co recommends: Pro plan ($25 per user, per month)

Dialpad Connect is the best cloud phone system for customer services teams, due to its massive selection of call management features, meaning that it can handle high call volumes. Examples include automatic screening, call routing, and voicemail transcription.

Opt for the Pro plan ($25 per user, per month), and you’ll also unlock third-party integrations to CRM tools including Salesforce, Zendesk, HubSpot, and ServiceNow. With these tools in your arsenal, you’ll be able to view all of your customer data in one place, and ultimately manage your correspondences with greater efficiency.

What do we like about Dialpad Connect?

Dialpad Connect is a moderately priced cloud phone system built with customer services teams in mind. Users can reach out to customers via email, phone, chat, and SMS, giving you the flexibility to nurture your potential leads in whatever way you see fit.

As already alluded to, Dialpad Connect excels in terms of call management features. You can customize your routing options for inbound calls, so that the experience for your end customer is as streamlined as possible.

Another area in which Dialpad Connect excels is security. On all of its plans, you can manage user permissions, roll out single sign-on, and lock meeting rooms, meaning that you can control what your staff are able to access.

This will prove particularly valuable for organizations that employ freelancers, such as a customer services team that scales up during peak periods.

What limitations does Dialpad have?

Dialpad Connect’s integrations library is not as robust as some of the other providers on this list, with 60 available tools, compared with more than 300 on RingCentral.

On top of that, we rated Dialpad Connect as one of the worst VoIP platforms for training features, with the provider missing tools like call monitoring, call barge, and call whisper. Because of these two shortcomings, Dialpad Connect is a poor choice for larger businesses.

How much does Dialpad Connect cost?

• Standard: $15 per user, per month
• Pro: $25 per user, per month
• Enterprise: Custom

4. GoTo Connect: Best Cloud Phone System for Unifying Internal Communications

• Entry-level plan: Phone System plan (custom pricing)
• Tech.co recommends: Phone System plan (custom pricing)

GoTo Connect is the best cloud phone system for unifying your internal business communications, with great tools including a team messenger, video conferencing with up to 250 participants, and a virtual fax manager.

For this reason, it’s a great option for businesses with multiple sites and/or hybrid workers.

What do we like about GoTo Connect?

GoTo Connect is a good solution for businesses that want to unify their internal communications. In particular, we found that the in-built team messaging and video conferencing platforms are helpful tools for keeping employees in the loop.

Beyond that, our research team was impressed by GoTo Connect’s selection of call management features, with robust tools including call routing and ring groups, which can connect you to the right person, even if they’re based in a different location.

The team also highlighted the ability to map out call flows via a simple drag-and-drop interface. This customizability is a great tool for training your new starters.

GoTo Connect has three plans, and we concluded that the entry-level plan, Phone System (custom pricing) is sufficient for most small businesses. The Customer Experience (CX) plan (custom pricing) and Contact Center plan (custom pricing) are oriented towards large organizations that process a very high volume of calls.

What limitations does GoTo Connect have?

GoTo Connect has a limited selection of software integrations, with scarce options for helpdesk platforms and customer service live chat systems.

Check out our GoTo Connect review to learn more.

How much does GoTo Connect cost?

GoTo Connect has three different plans — Phone System, CX, and Contact Center. None of them have public pricing, so you’ll need to contact the company directly for a quote.

5. 8×8 Work: Best for 24/7 Customer Support

• Entry-level plan: Work plan (Custom pricing)
• Tech.co recommends: Work plan (Custom pricing)

8×8 Work has the best help and support options out of all the cloud phone providers that we’ve tested. These platforms can be difficult to figure out, especially for users migrating from desk phones to softphones. To mitigate this, 8×8 Work offers comprehensive live support for all users.

What do we like about 8×8 Work?

We scored 8×8 highly across several categories, with particular praise for its robust training features, like call monitoring, and huge selection of integrations for CRM and helpdesk software.

I tested 8×8 Work myself, and I found it to be a highly intuitive platform, with a well-laid out interface and easy navigation. First-time users can benefit from a helpful tutorial, which walks you through the setup process.

Between the 24/7 live support and number of channels to seek help — from phone and email to chat and user forum — we did not experience a problem that 8×8 was unable to solve, with an expert team of service reps always on hand.

What limitations does 8×8 Work have?

The lack of transparent pricing will likely deter smaller, cost-conscious businesses. Furthermore, the most recent information that we have access to suggests that 8×8 Work is one of the more expensive cloud phone systems on the market.

How much does 8×8 Work cost?

8×8 has three plans available — Contact Center, Engage, and Work. None of them have public pricing.

Benefits of Cloud-Based Phone Systems

In 2026, the best cloud phone systems will have a myriad of advantages over traditional phone networks. These include:

• Resource savings: There are a lot of affordable VoIP phone services out there that are cheaper than traditional landline networks, not only in terms of initial installation, but in ongoing costs.
• Setup: As there are no telephone lines to install, a cloud-based system can be set up quickly and easily.
• Remote connectivity: Cloud systems can facilitate operations when teams are geographically dispersed, with remote staff being able to connect and take calls, regardless of their location.
• Advanced functionality: Cloud systems have a range of advanced features that can be added, such as extensions, management of messages, call forwarding and business messaging.
• Flexibility: Cloud VoIP systems allow companies to add an unlimited number of new users, no matter where they’re located. This way, you never have to stress about exceeding your phone system’s capacity and, with many providers, you only pay for what you need. By contrast, expanding legacy and other on-site systems is complicated and costly.
• Frees up resources: By hosting your phone system in the cloud, you can eliminate common IT headaches that arise from on-premises system glitches. Instead of spending time and money fixing phone problems, your team is free to focus on more important tasks.
• New features are easily added: If you host your phone system on-site, you’re limited to the features that the system comes with out of the box. Upgrading is a painful and expensive experience. Cloud systems use a single, centralized software platform. New features can be seamlessly added to all users at the same time without disrupting service or requiring the use of additional hardware.
• Disaster recovery: Some on-premises phone systems do offer redundancy and back-up features, but they require additional installation. Many cloud system providers, however, offer disaster recovery services as part of their initial implementation. In the event of a power outage, natural disaster, or other failure, calls are saved and rerouted to alternate lines.

How to Choose Your Ideal Cloud Phone System

Every business will be looking to get something slightly different out of a cloud phone system. If you’re unsure how to start your search, here are some important questions to consider:

• Features: Before you compare the market, you need to identify what you will be using the cloud system for. If you’re using the system to make sales, 8×8 will be a better match, while Vonage is the strongest system we tested for retail businesses.
• Integrations: You definitely want to be sure your cloud phone system can integrate with other business software, like top softphone apps, so check on those external connections before making a decision for your business.
• Scalability: Some cloud phone systems are a lot more scalable than others. For instance, RingCentral and Vonage’s modular packages are much more adept at scaling alongside growing businesses than more static options, like Zoom Phone.
• Security: If you’re a business that deals with sensitive information, like healthcare providers or legal firms, you’ll want to be sure your cloud phone system offers advanced VoIP security features like encryption and vulnerability updates.
• Call quality: Some cloud phone systems offer better call quality than others, so if you’re a business that needs crystal clear audio and no connection issues, you’ll want to consider that before you buy.
• International calling: If your company regularly makes calls overseas, we’d recommend opting for a provider that offers flat-rate pricing for unlimited international calls, like Zoom Phone.
• Desk phone compatibility: Some VoIP providers are only compatible with select brands of desk phones, so make sure your chosen provider works with your devices.
• Cost: Your budget should play a big role in deciding which solution to go with, especially because VoIP system costs can vary dramatically from one provider to another.
