Internet phone capabilities add power to business communications

It did not take long for VoIP to find its way from consumer use to business use. It soon became the preferred voice call technology of modern business phone systems, quickly replacing traditional telecoms. As a result, more organizations are able to recognize the multiple advantages of being able to place calls over the internet. Its positive effect on productivity and efficiency can only be matched by its quick return on investment. This also gave rise to different Voice over IP providers that are now competing against regular telecom carriers in the business telephony arena.

VoIP technology and internet telephony hardware

What is VoIP?

Let’s start from the top. 
Voice over Internet Protocol refers to the technology that allows people to make voice calls over IP networks in real-time. 
It is a telephony technology that allows you to receive calls over the internet rather than using traditional phones with landline phone services or telephone networks. 
VoIP technologies convert analog voice signals and other media streams into digital packets and send them to the recipient at the other end of the line via a broadband connection. 
Its set of telephony protocols work through packet switching, which allows digital voice data to travel across different networks like the internet. 
VoIP services provide internet-based communications that you can take anywhere. VoIP calls, online meetings, and voicemails can be made from any internet-enabled device, anywhere with WiFi connectivity or data access. You won’t need to rely on a local area network. That makes VoIP perfect for remote team collaboration and business travel. 
Plus, this kind of internet-based telephone service is extremely flexible. You can make VoIP calls from any mobile device, like cellphone and laptop, with any operating system (whether iOS or Android), as long as you have internet service.

Top VoIP features

VoIP isn’t just about making calls. VoIP providers offer tons of fantastic additional features like caller ID, call screening, and multi-level IVR, along with basic telephone systems and functionality. The best VoIP providers like RingCentral offer unified communications with VoIP solutions to streamline your business communications into one user-friendly experience.

Here are some of those top VoIP features:

Unified communications

Unified communications (or UC) allow you to streamline all of your business voice communications and other modes of communication under one multi-functional app. Instead of having one app for SMS text messages and another for making calls, you’ll be able to manage everything from one interface. 

UC platforms cover everything from audio conferencing to video meetings, team chats, screen sharing, and instant messaging.

RingCentral MVP brings messaging, video, and phone together so that teams can do their very best work from anywhere. Teams can chat, share files, and create dedicated threads for particular projects or topics. Plus, HD video meeting means nothing is lost by working remotely. Even if you’re all miles apart, you’ll feel like you’re in the same room.

Auto-attendant

An auto-attendant is a bit like a receptionist for your phone line. Having an auto-attendant is a great way to project a professional image for your brand. The automated system will greet incoming callers and guide them to the most appropriate channel, department, or individual representative. 

RingCentral MVP includes a comprehensive virtual receptionist service. Your virtual receptionist will greet customers dialing in and route them directly to employees’ headsets so that they never miss out on a customer service call or sales opportunity. 

Plus, it includes fully customizable calling features. You can add a unique company greeting, relevant extensions, business hours, call forwarding, and routing rules.

Call recording

Another great VoIP feature is call recording. Many VoIP service providers offer recording capabilities so that you can record phone calls between customers and your staff. It’s a great way to monitor how your team handles customer calls and spot any areas that need improvement. 

Rest assured, call recording is incredibly secure. Only authorized personnel have access to recorded content, and the recording itself will remain undetectable.

Advantages of VoIP

Needless to say, using VoIP comes with many advantages. Costs are generally lower, and accessibility higher. Other advantages include:

High voice quality

VoIP calls are super high-quality. Many VoIP providers offer HD calling and video. That means incredibly clear sound for conferencing, making you feel like you’re all in the same room. All you need is a high-speed fiber-optic internet connection for super crisp audio.

Accessibility

Most VoIP phone services include features that cost additional premium charges if you want them added to your traditional landline service. This includes features like call forwarding, call screening, and caller ID, not to mention that modern business VoIP systems are also inclusive of higher-level call management features like cloud PBX and answering rules.

Mobility

Again, unlike traditional phones that are tied to specific telephone units, VoIP can be accessed anywhere as long as you have an internet connection. This provides users, especially businesses, mobility that does not cost as much as cell phone minutes.
When you can call from any IP network, it means that you can take your business with you wherever you are. Today’s businesses need mobility, and that’s exactly what you get with VoIP. 
With RingCentral, you’ll be able to access your VoIP phone services and management tools from anywhere, even with your mobile phone. Simply access and manage your RingCentral channels through your online dashboard. It’s that simple.
The best part is that users are able to use their official business phone number wherever they are. This opens a lot of opportunities for remote and flexible work options for businesses.

Scalability

Last but not least, VoIP can be scaled with ease. It’s so simple to add new users and increase provisions as and when your business requires them. This ability to scale up and down according to demand makes VoIP the ideal choice for any kind of business, from small business startups to fully blown enterprise-scale organizations.
Getting a new phone line through traditional telecoms is not as easy, even if you already have an existing line with them. New phone lines in this setup need new cabling and new hardware. In addition to this, you cannot do the installation yourself because it requires specialized manpower.
That is not the case with VoIP. Ordering new phone numbers and activating them only require a few taps on your mobile phone or a few clicks on your computer. VoIP phone numbers are not tethered to a single device, so they can be accessed from anywhere. There’s no need for the installation of new cables because VoIP uses IP networks as transmission lines.

Disadvantages of VoIP

Despite its great features, VoIP’s main issue is internet dependency. A reliable internet connection is essential if you want to use business VoIP. With low network bandwidth or in the event of an outage, your service will be compromised.

VoIP needs the internet to work.

The main limitation of VoIP is that it is entirely dependent on your broadband connection. No internet means no VoIP.
That’s not all. Poor internet connection can also affect the quality of voice calls. Some companies have invested in internet service to be used solely for VoIP so that it does not have to compete with other internet transmissions within the organization and ensures enough bandwidth for voice calls.
If for some reason you cannot get a dedicated internet provider for VoIP, another solution is to use specialized QoS (quality of service) routers. These routers can be set up so that they prioritize VoIP transmissions over other IP transmissions, ensuring the best quality of calls using your existing internet connection.

VoIP is not always secure.

Data traveling through the internet can be intercepted by third parties, and that includes VoIP transmissions. This means your voice calls can be in danger of being hacked or breached and can fall into the wrong hands.
That is why the most reputable VoIP providers employ, at the very least, high-level encryption to protect voice calls during end-to-end of transmission.

Why VoIP is good for business compared to conventional landlines

Traditional phones

  • High up-front cost for on-premise hardware
  • Implementation is expensive and complicated
  • Contracts are compulsory and have early termination fees
  • Additional fees for every service and hardware upgrade
  • Additional fees for technical support
  • Maintenance calls for specially-trained personnel
  • Implementation of service change requests takes time

VoIP phone service

  • No hardware needed
  • Implementation is quick and free of charge
  • There are no monthly contracts
  • New features are implemented at no extra cost
  • Free round-the-clock customer assistance
  • Changes can be made using your own account
  • Adding or repurposing phone numbers can be done as needed

Do I need a VoIP service provider?

Yes. You will need a VoIP service provider to set up a VoIP business phone system. As the name suggests, VoIP service providers are companies that offer VoIP services to businesses and individual consumers. 

Whether you are operating a small business or a large enterprise, the advantages of VoIP over traditional carriers are very obvious despite some disadvantages.

Mobilizing a cloud PBX (essentially a virtual PBX system) creates an automated answering system to direct incoming calls to your business phone.

And don’t forget to factor in your anticipated future growth. Service providers like RingCentral offer scalable VoIP solutions that cater to every business size, from small businesses and startups to large enterprises.

Look for the one that can give you the most bang for your buck. Modern business VoIP providers no longer just provide VoIP; these days, they offer entire business communications solutions. VoIP phone systems no longer just let you make and receive calls over the internet, they also let your business send internet faxes and business SMS, manage and route all incoming calls, and even let you host and join audio and video conferences from anywhere.

Do not settle for the cheapest VoIP phone service you can find. After all, not all providers are created equal. Go for the VoIP provider that can solve all the communication needs of your business.

Defining “VoIP provider”

A VoIP provider is a business entity that offers VoIP services directly to consumers or businesses.

VoIP, or Voice over Internet Protocol, is the technology that allows for the use of IP networks to perform telephony functions, such as making and receiving a phone call.

It’s usually offered in the SaaS model, wherein the software is provided as a service (hosted by the vendor) rather than as a product (downloaded by the user).

There are many VoIP phone system providers out there, so it’s essential to choose wisely. Look for a VoIP phone service that offers all the phone features and functionalities you need. 

If you want to enjoy the benefits of VoIP (which include savings, scalability, flexibility, and mobility), then yes, you need VoIP for your business. It is just a matter of choosing the right VoIP provider for your company.

What this means is that instead of selling software to customers, hosted VoIP providers have customers subscribe to a service.

What are the different types of VoIP providers?

There are different types of VoIP providers in the marketplace. They generally fall under these three:

VoIP-only providers

There are providers who focus solely on directly providing telephony functions for businesses and consumers. This may include some basic features, like voicemail, call forwarding, and caller ID, but usually no call management features are included. If you are only looking for phone calling functionality and not much else, then these providers may already be on your radar.

VoIP with cloud phone system providers

There are providers who leverage the cloud by combining VoIP with cloud PBX technology. These cloud-based phone systems have VoIP as the foundation of their telephony component combined with the advanced routing capabilities of a hosted PBX. Aside from the ability to make and receive calls over the internet, these providers offer businesses call management features like auto attendant, answering rules, and virtual extensions for departments and individuals.

VoIP as part of unified communications solution providers

These are providers that are similar to VoIP with cloud phone system providers, but they take their offerings to another level. These companies combine different communications tools, like VoIP, cloud PBX, online meetings, and team messaging, into one platform. This provides businesses a central hub for communications instead of having to use different vendors for different communication tools.

How to choose a service provider

As you start shopping around for your new VoIP service, a few things are worth keeping in mind. It’s worth considering these essential features before making any investment.

1. Know what VoIP is first.

Before hopping into using any new technology, you have to do your research to understand it and how it will affect your company. The same applies to VoIP, especially since it will be the basis of how your business communicates.

  • Cost - Is it affordable?
  • VoIP Apps - Make sure there’s a full-featured mobile VoIP app. 
  • Integrations - Look for third-party integrations with your other business tools, such as your CRM.
  • UCaaS - Make sure that you’re getting more than just calls.

2. Know your business communications needs and how VoIP can solve them.

Now that you understand what VoIP is, the next step is to figure out how it can help your business. To do that, however, you’ll have to start by identifying the business communications needs of your organization.

Some of the questions you may want to ask in regard to those needs are:

  • What type of business phone number does the business need? Does it need a toll-free number, local number, international number, or any combination of the three?
  • Does your business make a lot of outbound calls?
  • Does your business receive a lot of inbound calls? Do you need a call routing solution?
  • Do you have multiple locations?
  • Do you have a distributed workforce? Do you have remote workers or telecommuting workers?
  • Do you use fax and/or business SMS?
  • Do you need an audio or video conferencing solution?
  • Do your teams collaborate a lot?
  • Do you want your business tools to integrate with your communications solution?

These are just some of the questions you should ask yourself as a business owner on the lookout for new phone solutions. Once you have identified your operational needs, you can start to look for VoIP providers that can meet your requirements.

Here is a checklist of some of the most common business communications needs:

  • HD-quality VoIP phone service
  • IP desk phone and conference phone support
  • Online fax service
  • Online meetings software (video conferencing and teleconferencing)
  • Business SMS/MMS
  • Screen sharing
  • Business phone numbers—toll-free, local, international
  • Team messaging
  • Call management system/hosted PBX
  • Task management
  • Auto attendant with advanced call routing
  • File sharing
  • Call queuing
  • Analytics and reporting
  • Virtual extensions
  • Automatic call recording
  • Call forwarding
  • Call monitoring
  • Call screening
  • Messages/music-on-hold
  • Voicemail
  • Integrations with popular productivity apps
  • Telepresence
  • Softphone for laptops and desktops
  • Open APIs (voice, SMS, messaging, data, etc.) for integration with in-house apps
  • Gallery of current integrations with popular business apps (i.e. CRM integration with Salesforce, productivity app integration with Office 365 or G-Suite)

Can your potential business VoIP providers address them? You can use this list as a starting point. Just cross out items that don’t apply to you and add what’s not mentioned.

Once you have a detailed list, you can move to the next step.

3. Check different VoIP providers for business (and what their plans include).

There are a number of VoIP providers that might be able to meet your business communications needs—you just need to narrow it down to one. 

Check all the call plans and packages offered by each of the reputable providers you were able to gather.

Most of these plans have tiers, so make a side-by-side comparison of the prices and included features for each plan by tier.

This way, you can see the differences between the basic, mid-range, and premium VoIP plans and prices for each provider.

4. Determine the VoIP provider’s reliability and security.

Even if a VoIP provider meets all your business communications needs, your scrutiny should not end there. You also have to determine how they keep their service reliable and secure.

To ensure reliability, the top VoIP providers also have multiple data centers set up in different locations. The idea is that multiple servers in multiple data centers result in redundancy of service. This means that in the event that a server fails, another server can take over in real time. The same goes for when a whole data center goes down, another data center can take over the service so that there will be no disruption.

Other security and reliability practices that top VoIP providers employ include:

  • Regular audits of data centers
  • Support of Multi-Factor Authentication (MFA)
  • Advanced account management and administration
  • Robust and secure networks

5. Check the VoIP plans and pricing of the vendor.

If you have noticed, plans and pricing are mentioned last. That is not a coincidence. Like with any commodity in this world, price should not be the first factor you look at when you’re looking for quality.

There may be lower-priced VoIP services, but their reliability and security can be questionable. There is also a reason top providers charge more for their service. The research and development they invest in to put out the best product is part of what you are paying for.

In this step, you should have a clearer picture of which VoIP providers meet most, if not all, of the items on your checklist.

Only after you have streamlined your list should you consider price. Of the providers on your list, which one gives you the best value for your money? From there, it is a matter of choosing which one will best solve your communications needs. That vendor should be your top choice.

6. Look for the leading VoIP provider in business communications

Another factor you should look at is the reputation of the VoIP provider you are evaluating for your organization. While it is difficult to separate valid reviews from spam reviews, it’s still worth investigating the general opinion people have about the company.

One thing you can look at is the number of subscribers. Generally, when a provider has a large number of users, it means they are trusted by their customers and the industry to provide reliable and secure service.

Another thing you can look at is the brands that trust the provider for their communications. Big brands do not just sign up for a service; they do their due diligence and get assurance that they will get a good return on investment.

If you are truly looking for the best provider, however, then you should go with an industry leader. RingCentral is the leading provider of not only VoIP but also unified communications as a service (UCaaS), which addresses multiple communications problems in one platform.

RingCentral also adapts to how your business operates. It has integrations with some of the most popular business apps like Salesforce®, Google Workspace, and Microsoft Office 365™. It also has open APIs that give you the power to add a communications component to your in-house apps.

It is the most complete solution in the market right now.

Frequently Asked Questions (FAQ) About VoIP Providers

By itself, VoIP is not a secure service. The data it transmits passes through the internet, which is a public network. This makes said data susceptible to interception or breach, especially during transmissions.

However, security measures can be deployed to protect data during VoIP calls.

One of the most effective security measures employed by top providers is strong high-level encryption. Encryption refers to the process by which data, in this case, voice calls, are converted from the original form to an encoded version that can only be decoded via a decryption key. It is the most important measure in securing data for end-to-end transmissions across IP networks.

Yes. Over time, VoIP calling is significantly cheaper than the standard phone bill for network calls on an analog phone. VoIP providers offer very low rates for international calling. With RingCentral, each country has different international calling charges, so you’ll need to check the rates before you start calling.

Yes. This is called number porting, and it’s the process of transferring your phone number from your current phone service provider to your new one. Most service providers allow you to port your old number over to your new plan. 

With RingCentral, it’s straightforward. 

Simply log in to your RingCentral online account as an administrator, navigate to phone system > phone numbers > transferred > transfer numbers.

The price of VoIP plans varies depending on your business VoIP provider and the particular service package you choose. RingCentral MVP plans start at just $19.99 per user per month for messages and phone calls. For more features, check out our standard, premium, and ultimate plans.

The best VoIP providers have a responsibility to provide their customer base a reliable, secure, flexible, and scalable VoIP solutions. If any of these qualities are not present, then these providers are far from being the best.

There are many providers that claim to be the best, but you can’t simply take their word for it. What RingCentral can offer your business is a reliable solution with 99.999% SLA that is supported by redundant architecture housed in bi-coastal data centers. RingCentral also employs a combination of different high-level security measures and best practices to keep the VoIP-based communications solution secure.

How to recognize a good VoIP provider for business

The adoption of Voice over Internet Protocol changed the way businesses communicate. No longer shackled by old and on-premises systems that are going obsolete, organizations are now able to achieve flexible and mobile communications without the high phone bill.

But with the rise of business VoIP comes the emergence of multiple business phone providers trying to get a piece of the growing revenue pie. As a result, it has become more difficult for businesses to recognize which VoIP companies are reputable and which ones will only give headaches and poor service.

To help you out, here are some things you should look out for to determine if a VoIP provider will be good for your business:

Quality of VoIP service

VoIP can only be a viable option for your business if it can provide similar or better voice quality compared to regular landlines. But how do you test it without signing up for the service?

Most of the best VoIP providers have a means of showing customers the type of call quality they will experience using their current broadband connection. For example, RingCentral has a QoS speed test page where you can simulate multiple VoIP calls to see how many your network can handle before the quality degrades.

It is a helpful feature that not only shows the quality of call you will be getting, but also the capacity of your current network.

Reliability of phone service

Another question about Voice over IP is its reliability compared to landlines. Find out what measures are taken by the provider to ensure that the phone service will have minimal to no downtime.

RingCentral, for example, hosts its system in multiple data centers across multiple locations. This ensures redundancy so that if a server or a whole data center encounters some issue, other servers or data centers can take over. This makes it so that there is no disruption of service. Keep in mind that the best VoIP system is the most reliable one in the market.

Security of VoIP and the whole phone system

Your voice and other important data will be traveling the public internet during a VoIP transmission. A good vendor will have tight security measures and policies in place to ensure it gives users access to VoIP technology while protecting their phone system from any security breach.

RingCentral employs several security measures and policies, which include high-level encryption that protects VoIP calls during transmission and when at rest. It also conducts regular data center audits and employs multi-factor authentication and Single Sign-on for additional account protection.

Trusted by customers

Truly good business VoIP service providers are beloved by their customer base, which makes this a true indicator of whether a VoIP company is reputable or not.

Check out reviews, but take some of them with a grain of salt because these can be manipulated either by the company itself or by its competitors. Keep it simple by looking at their number of subscribers.

As a case in point, RingCentral is trusted by more than 350,000 companies worldwide, including some of the most popular brands in the market.

Peer-recognized business VoIP provider

The best providers are recognized by its peers. RingCentral, for one, is recognized by several respected organizations including the following:

  • RingCentral is a Leader in the 2019 Gartner Magic Quadrant for Unified Communications as a Service, Worldwide.
  • RingCentral has been ranked #1 in Omdia’s 2020 North American Unified Communications as a Service (UCaaS) Scorecard.

Accolades like these show that a provider is reputable and has a history of providing good service. RingCentral certainly fulfills each criterion.

Best VoIP - Choosing the best VoIP provider based on your business communications needs

Even if you have whittled your list down to the most reputable Voice over IP providers, choosing the right one for your business is still difficult.

Unlike consumer apps that you can just uninstall if you are not happy with them, business VoIP phone systems have to be implemented organization-wide before you can see if the service works for your needs or not.

Even then, it may take months (or even years) to decide whether you want to keep it or go for another provider.

That is why it is important that you make the right decision on the first try.

By now you already understand the importance of having a VoIP service provider. But if you’re still unsure which vendor to choose, you can try RingCentral for free!
