When your customers are ready, you will be there. And you’ll be able to speak with them (or vendors, partners, shareholders, and other third parties) in the way that they prefer. Nextiva’s plans deliver voice and video calling, as well as texting, plus separate add-ons for call centers and live chat. 

And handling a ton of inbound calls is never a problem.

Plus, you can port your U.S. or Canada-based number over for free.

RingCentral logo

RingCentral is a boon for organizations that have managers that need to monitor external calls and coach reps up to perform better on them.

Ooma logo

Ooma is the favored platform for companies that still have most or all of their employees under one roof. It boasts a bevy of call management features in a system that allows you to use your own equipment or even add new desk phones through Ooma’s hardware on offer. And you can set up equipment yourself in less than 20 minutes.

You get all the key call management features, from virtual extensions for each of your team members and a virtual receptionist for directing calls to call parking, ring groups, and transfer and hold music.

You get over 50 features out of the box with the Ooma’s Office Essentials plan, which many users have stated has saved them a good deal of money over the long haul (particularly when you compare it to some of the price points of the other big names in this space). 

The Essentials plan starts at $19.95 per user per month. But if you want access to Ooma’s desktop app, text messaging, video conferencing, and other perks, you’ll need to upgrade to Ooma Office Pro—starting at $24.95 per user per month. The extra $5 is worth it for most businesses.

11Sight logo

If you have an inbound sales team that wants a unique way to let customers get in touch with you, you will love 11Sight.

If you’re just looking for a platform for external communication with leads, prospects, and customers without any unnecessary collaboration features, you can get all that you need from 11Sight while paying far less than you would with, say, Nextiva or RingCentral.

11Sight is revered among marketers. Since any interested party can initiate a sales call in one click, this platform can cut down your sales cycle time in half.

Plans start at $24 per month with yearly billing. Start your 14-day free trial today.

The Best VoIP Providers and Phone Services for Internal Communication

Business phone services are not all about taking incoming calls. You also need your team to collaborate amongst themselves, whether in the office or disperse around the country or globe. These employees will need to share files, message each other, and initiate huddles and meetings when they need to work together and get the job done. 


Nextiva logo

Being able to communicate clearly and cleanly within your business is what keeps things running smoothly. Nextiva allows for this with a ton of features.

You get unlimited video chat and messages between teams, which includes private messaging groups, file sharing, and more collaborative features. 

Bullet list of Nextiva VoIP collaboration features.

Often, hopping on a video call and sharing your screen is much better than writing out a huge message to a teammate. With one click, managers can request new tasks from employees, project members can huddle on deliverables, or departments can hold regular meetings to outline their work for the day, week, month, or quarter.

You also get custom reports, voice analytics, and real-time statistics that show how your team is performing on any external calls they may field as well. One simple-to-use dashboard holds everything. 

Get the full scoop in our full Nextiva review.


RingCentral logo

RingCentral’s 360-degree communication platform boasts plenty of collaborative features to help with internal communication. Team messaging, file sharing, and video conferencing for up to 200 participants all come on their MVP plans, so it’s an easy way to knock out internal and external communication needs in one platform.

Mature organizations that are behind the times on modern collaborative technology will be thankful for how easy RingCentral is to set up and manage. Admins find it easy to implement at the outset and even easier to stay on top of, whether that entails adding new users or phone lines, managing available features, or conjuring metrics and reports.

That same ease of use extends to the end users of RingCentral, with an interface that’s friendly to the less tech-savvy folks in your organization. Plus, between the desktop apps, web portal, and mobile app, users and admins alike can wield RingCentral from anywhere they’re working.

For example, RingCentral helps your team save time and communicate more efficiently through its team messaging, where users can send a direct message to another team member, share documents, and collaborate on those documents. You can also quickly switch from one form of communication to another, such as answering a text from a client while in the middle of a video call. Just switch to the text option in RingCentral, send your message, and return to the video call with just a couple of clicks.

Get the full picture by reading our comprehensive brand review of RingCentral.

Microsoft Teams

Microsoft Teams logo

If you already have a Microsoft 365 subscription you have access to Microsoft Teams. That’s a huge leg up in your decision-making process. What’s even better is that means you can use Teams’ internal communication and collaboration features at no additional charge. 

You get team messaging, video conferencing, and file sharing in a familiar, trusted setting. In addition, you can also add voice calling features, including forwarding, warm transfers, and transfers direct to voicemail. 

While it takes some work to make Teams handle calls outside your organization (you’ll need to integrate it with what existing telephony you have in your office or pay separately for Teams’ phone service), it’s a cinch to set it up for your internal communication needs. And, even if you’re not already subscribed to Microsoft 365, a standalone paid plan of Teams is much more affordable than most of the other names on this list.

MS Teams, on its own, starts at $4 per user per month. Or you can get it included with Microsoft 365 Business for just $6 per month. If you’re interested in the latter, you can try it free for one month. Annual billing is required for both options.

Take a look out or Microsoft Teams company review right here. 


1-VoIP logo

1-VoIP is the best option for an office using traditional desk phones with infrequent calling needs. You pay by the minute, so it will get pricey with a lot of usage but really satisfy your budgetary needs if you don’t lean on it too much. 

You have access to conferencing calling features to help teams stay connected within the company, as well as the ability to integrate text messaging, so any remote or field workers can stay in the loop with ease, too. 1-VoIP also takes care of setting everything up to your liking for cloud-based PBX deployments. 

Be mindful of their pricing options, though. The entry-level plan business plan starts at just under $15 per extension per month, but charges two cents per minute on any call. The next step up is more expensive, but allows for unlimited monthly calling. So the latter would be a cheaper option for high-volume callers.

All plans come with over 40 standard features and a 99.999% uptime rate. Select 1-VoIP packages even come with a free phone, which is a great value considering their phones start around $100.


3CX logo

The risk of picking a provider you don’t like is a real concern. But 3CX has a free forever plan that supports up to ten users.

So if you’re running a small team, you won’t have to worry about paying anything. However, larger teams can still use this free forever plan as an extended free trial to test 3CX before rolling it out organization-wide. Paid plans start at $175 per year per system for ten users and $275 annually for up to 20 users.

They are rated the best provider for the hotel industry because of the internal communication service they provide. Large hotels need to provide room service, messages, and requests amongst staff, provide programmed wake up calls, and have conference calls with clients and stakeholders. And that is the tip of the iceberg.

So, they might just be the best fit for those of you that have organizations which will stay small or that inhabit specialized industries like hospitality. 


Phone.com logo

If you are looking for a flexible and inexpensive plan that can be molded to exactly what you need, Phone.com is the way to go. That’s because this plan allows you to give more of your phone services to the employees who need it more often than others.  

Phone.com is also perfect for seasonal work, so if you are more busy during the holidays or other peak seasons, you don’t have to pay full price for services all year. Just bump up your plan at the appropriate time. Even if that just entails that your team tends to need to communicate with one another more during every other month, you can easily scale up and down to keep your budget and bottom line happy.

All plans include inbound call routing, call transferring and forwarding, and call schedules that provide special routing options for incoming calls. Phone.com is also the first provider that we’ve reviewed that gives you the option of a live receptionist for a monthly fee, which is great for fielding client, vendor, or stakeholder calls during those mad collaborative rushes.  

Plans start at $14.99 per user per month, and. you can save 15% with annual billing.

Vonage logo

If you want to customize your phone plan for your call center, Vonage is one provider that makes that easy on you. You get a buffet of phone services to choose from and add to Vonage’s base plan; you’re just not stuck with preset plans and packages. 

While that does make pricing a little more confusing to understand—for example, call recording is a paid add-on, but it can be heavily customized itself—you have the freedom of tons of options to choose from based on what you want Vonage to do for your call center. 

On the base plan, Vonage delivers standard call management features like routing, queues, parking, and a virtual receptionist. You can also tap into helpful UCaaS and collaborative features like SMS texting and team chat. And, explore unique offerings within Vonage, like call announcements, call screening, and tying multiple devices to one extension.

Plans start at $14.99 per line per month with 20 or more lines. It’s $17.99 per line for less than 20 lines and $19.99 per line if you have four lines or fewer.

CallHippo logo

If you have an outbound call center or a collections agency, CallHippo is the way for you to crank out more calls, get more sales, recover debt, or get more offers in front of more people. 

That’s because you can send out voice messages to multiple people in the form of a call. It’s called voice broadcasting and it uses AI speech transcription and call script software to automatically whip up and disseminate your message.

RingCentral logo

Zoom logo

Zoom allows two convenient options for international calling. 

If you will be calling regularly, just add an extra package that gives you unlimited calling to 18 different countries. Or, opt for getting a local number in one of 40 different countries through Zoom which will allow you unlimited calling within that locality. 

What’s nice about getting that localized international number is the presence and trust you can build if your business is making serious inroads in that country. 

If you’re not sure if you will need international calling, Zoom will let you make calls that are charged by the minute. That can get a bit expensive if you do it too frequently, so be mindful of the rates and how they compare to Zoom’s international plans.

Learn all about Zoom in our company review


8x8 logo

8×8 is a cloud-based VoIP provider that is easy to set up and doesn’t require any equipment. But the basic plan doesn’t include international calling. You’ll have to move up to the X2 plan, which allows you to call 14 different countries with no limits or restrictions. The top-tier plan raises the number of countries you can call to 48. 

8×8 prides themselves on reliability and offers some of the best call quality. In fact, several users confirmed that before switching to 8×8, calls were being dropped left and right. But now they are receiving much more stable call quality, even when calling the opposite side of the globe.

Plus, your quality doesn’t suffer depending on the device you are using. No matter if you use a hardline, mobile phone, or computer, your customers won’t be complaining they can’t hear you.

GoTo Connect

GoTo logo

If you need one platform that gives you tons of reliable ways to connect, then GoTo Connect is your saving grace. They are cloud-based so it doesn’t matter where you are in the world. You can reach your clients, customers, and teams with no issue. 

Even GoTo Connect’s entry-level standard plan supports international calling, which isn’t something you’ll see from every provider. You’ll be charged per minute at this level, which is fine for infrequent calls overseas.

But if you’re on a GoTo Connect standard plan, you’ll unlock access to free calling in more than 50 countries. These plans also provide you with loads of communication and collaboration features. Your limits for other features jump significantly here as well. For example, video meetings on the Basic plan are capped at four users, but you can have up to 250 users in a single meeting at the Standard tier.

Another bonus is users rave that, even with a poor internet connection, the mobile app works very well. That’s great for widely dispersed organizations that may be based in one country and have employees in another country calling customers, clients, vendors, or stakeholders in a third locale. 

There are two plans to choose from—Basic and Standard. These start at $24 and $29 per user per month, respectively.

What Matters When Reviewing VoIP Providers and Phone Services

We understand all the anxiety you feel when having to pick new software and platforms for your business. So our research team spent an enormous amount of time dissecting features to remove any uncertainty about which ones matter most to the use cases of your business.

Inbound Call Handling

When a customer reaches out, they expect quick and straightforward connections with your team. And, they expect a clear connection so conversations happen without confusion. Callers want to be transferred to the right person the first time and your team members want to make sure they’re only getting the right calls sent to them. 

When It Matters Most:

  • External communication – You want seamless call transferring, automated call attendants, and reception features that quickly get customers the help they need. 
  • Internal communication – Calling between team members and departments should be easy because of features like easy extension dialing and call routing. 
  • Call centers – It’s paramount to have an inbound call center services provider that can handle high call volume while always directing calls to the right rep at the right time. 

Outbound Call Efficiency

Making outbound calls can take a lot out of your employees. And this affects how efficient and accurate they are when it’s time to close a sale or connect with a vendor or client. So, having a provider that makes outbound calling easier gives your business an edge other teams lack. 

When It Matters Most:

  • Call centers – Power features like auto dialers and progressive or predictive dialers can make reaching out to call lists en masse easy on your reps.
  • External communication – Outbound sales agents need tools to limit the time they’re spending listening to ringtones, and leaders need powerful dashboards to help track outbound performance.
  • International calling – Due to the higher costs associated with international calls, ensuring outbound efficiency is crucial to avoid high per-minute rates on wasted calls.

Call Recording and Transcription

If you want to improve your customer service, sales and marketing efforts, or lead generation, you need to know what you’re doing well and what needs work. Being able to record your calls and examine exactly what your reps are saying is an invaluable feature to have. 

When It Matters Most:

  • Call centers – Recordings and transcriptions of calls are paramount to critiquing and training your reps, as well as having records in the case of any disputes. 
  • Remote work – Businesses can use call recordings and transcriptions to keep remote employees in the loop if they missed something important.
  • Internal communications – Teams will stay more engaged during internal meetings if they don’t have to take live notes and can refer back to recordings for meeting summaries.

Easy Setup

This is the biggest concern for most business owners and call center managers. If the process to get started on a VoIP platform is complicated, how hard will using it be? We get it. Many of the providers we selected on this list make that as effortless as possible, but it’s always a sliding scale based on the complexity of the implementation and your own tech-savviness (as well as that of your team members). 

When It Matters Most:

  • Remote work – Some providers specialize in creating remote working environments without hassle, while others assist remote workers through effective mobile apps. 
  • Virtual phone numbers – Being able to add new numbers or port existing numbers should be simple and not laden with hidden costs or long waits. 
  • Internal communication – Make sure a provider can easily implement all the features your team will use most to collaborate and stay connected. 


Features that let teams work together seamlessly (from anywhere) are crucial to an effective phone service. The specifics vary, depending on whether you’re leaning on your system for internal needs, external communications, or a bit of both.

When It Matters Most:

  • Remote work – Look for the keys to keeping your team in the loops, such as teach chat, unlimited video calling for huddles and meetings, and file sharing. 
  • Internal communication – You’re going to want the best rate for a full UCaaS package, one that encompasses everything from remote work tools and traditional voice calling to faxing, mobile apps, call management, and call flow tools.
  • External communication – You’ll want the full array of features here, so that external parties can reach you and be reached in any form they prefer from video and voice to faxing and texting. 
  • Call centers – Training and monitoring for quality are the things that help the most here, embodied in features like barge and whisper, as well as call recording and transcription. 

Keeping Your Number

Not every business wants to acquire a new or virtual number from their new VoIP phone service provider. Number porting should always be an option, though some providers make it easier or cheaper than others. 

When It Matters Most:

  • Call centers – You’re going to lose a lot of trust if your help line or support center changes its number after customers have gotten used to dialing the old one. 
  • External communication – Having a consistent number is what keeps the sales and recurring business coming in, just make sure internal transferring is a feature that’s offered and is easy to set up and manage. 
  • Virtual phone number – If you’re switching from a traditional business line to a virtual phone system, you may want to consider porting your number to your new VoIP provider.

Worry-Free Reliability

This should be a given for all VoIP phone service providers, but it’s not always the case. Find a provider that offers the best security and reliability, backed by a strong SLA or guarantee. You should always run a VoIP speed test to make sure your existing connection can support your new service provider. Taking steps to optimize your VoIP network will also help improve the quality of your calls on reliable systems.

When It Matters Most:

  • External communication – Kind of obvious, of course, but any external communications with customers, clients, and other parties need stable connections and good call quality across voice and video.
  • Call centers – The fastest way to get a bad reputation as a call center is to frustrate customers with calls that drop in the middle of resolution or where the quality is so poor that they just give up and hang up. 
  • International calling – Why pay expensive international calling rates (or pay for a pricey separate plan) if calls you place to or receive from other countries are of terrible quality?
