Benefits of a VoIP service

RingCentral VoIP service is encrypted with secure voice between endpoints on the network—including desk phones, RingCentral for Desktop, and, with VoIP calling enabled, the RingCentral mobile app.

Why does this matter for your business? A secure VoIP service provider ensures that your business communications are protected from service interruption threats such as natural disasters, power outages, and malicious attacks. Without a secure, reliable VoIP network, downtime can have dire consequences for your bottom line. For example, with a traditional PBX, a simple power outage could result in lost customers or prospects who are attempting to call your business, which ultimately results in loss of profits.

RingCentral provides businesses with carrier-grade reliability and security, with Tier 1 network centers and 24/7 monitoring to ensure your VoIP service isn’t disrupted. RingCentral’s geographically dispersed data centers provide redundant layers of security—at the perimeter, at the service delivery layer, and with SSL-encoded web applications.

To ensure the best possible call quality on all of your phone calls, RingCentral offers customers the tools to check your internet connection speed as well as instructions on how to configure your router properly. Keep in mind that several key factors can impact the quality of service (QoS)—including high-speed routers that prioritize voice traffic over lower-priority traffic, such as large downloads. To see if your current bandwidth can support VoIP, test it for free here.


As the leading business VoIP provider, mobility is at the heart of RingCentral’s VoIP solution. RingCentral’s VoIP technology is mobile-ready and is ideal for bring your own device (BYOD) initiatives.

  • Telephone service maintenance contracts
  • PBX replacement and upgrade parts
  • Cost of connecting multiple locations
  • Telecom charges for local, long-distance, international calling,* or toll-free calls

VoIP phone service for business

Voice over Internet Protocol refers to the technology that allows us to make and receive phone calls over the Internet in real time. It is a set of protocols working together to deliver internet telephony functions similar to regular phone lines or PSTN (public switched telephone network). The difference is that VoIP phone service provides flexibility and mobility that is not possible with traditional telephony. By delivering voice calling functions over internet services, it allows anyone to use Voice over IP from anywhere via their laptops, desktops, desk phones, cellphones, or smart devices.


Traditional phone services
  • Pay thousands of dollars for on-site traditional phone system hardware
  • No free calls-long distance and international calls are costly and paid per minute
  • Business features come with extra cost
  • Requires additional physical cable lines for traditional landline expansion
  • Can remain active during outages
  • No expensive hardware required, so you save money up front
  • Free VoIP calls-long distance calls, if not entirely free, only require nominal fees
  • Comes with standard business phone features like call monitoring call forwarding, voicemail, and others
  • Add-on extensions require a few clicks or taps on admin control panel
  • Needs the internet to deliver service

The popularity of VoIP across all kinds of businesses has driven many VoIP service providers offering this technology to lower their costs in order to attract more clients. As such, it’s easy to fall for a VoIP provider that offers the cheapest solutions.

You as the consumer shouldn’t be looking at the initial price alone but at the total cost of ownership, which is the sum of acquiring, deploying, and operating a VoIP phone system over its entire life cycle. Be sure to look at the upfront, deployment, operational, and upgrade costs.

  • Upfront costs
    Comprehensive, high-quality systems naturally come with higher upfront costs, but they are more reliable and easier to maintain—and still offer 30% cost savings over legacy phone solutions. Outside of the VoIP service pricing package, you should also take into account the cost of headsets, webcams, and a strong network connection to ensure call quality.
  • Deployment costs
    Get a service provider to design, implement, and configure your cloud-based VoIP system. Then you’ll need to hire experts to teach your employees how to use the system properly and effectively. A more experienced, knowledgeable provider can have all these covered for you.
  • Operational costs
    Think of the monthly recurring phone service costs, which may be dependent on the plan you choose. For instance, there are companies that offer long-distance calls per minute and there are others that provide unlimited calls for a fixed monthly fee. If you are managing your VoIP phone system on your own, you also have to consider the power, cooling, and maintenance costs on a monthly basis.
  • Upgrade costs
    Be sure to set aside some budget for when you need to make any upgrades. Then again, if you chose a hosted VoIP provider, you don’t have to worry about anything.

Compared to the traditional phone, with VoIP, you can make phone calls through the internet. This means that instead of a desk phone or a landline, you can make calls through your mobile phones, tablets, and even your desktop, as long it's hooked to an internet connection. 

Through VoIP technology, your voice converts into digital packets so it can travel through the internet across various networks and vice versa, so participants in the call get to have a conversation.

This technology enlists the help of several protocols or rules which help in routing data, such as:

  • Session Initiation Protocol (SIP) to help conversations happen in real time,
  • Real-Time Transport Protocol (RTP) which carries each digital voice data packet in real-time, and
  • Transmission Control Protocol & User Datagram Protocol (UDP) are responsible for the accuracy and speed of digital signal and data exchange.

On the business aspect, VoIP allows businesses to grow exponentially. Because you are not tied to a landline, you can connect to any mobile device the company wishes them to have. You can also strengthen your relations with your customers, partners, and your team through collaborative VoIP solutions such as audio and videoconferencing, among others.

You can also leverage and modernize your business phone systems with VoIP as the core of your telephony. With a VoIP service, you can easily handle incoming calls and create outbound calls performed by cloud-based servers that perform these call routing functionalities. Thus, a VoIP phone system is beneficial for every business, may it be enterprise, middle-sized, or small businesses alike.

Voice over Internet Protocol (VoIP) is the way to go for businesses

Businesses that streamline their workflows and optimize their operations are the ones that usually have a better chance at success. With massive, real-world benefits like the ones listed below, it’s easy to see that VoIP technology improves not only business communications but also business productivity.

Traditional phone systems can get really expensive. In fact, they’re up to 30% more expensive than a VoIP phone system. All the system upgrades, changes, maintenance, and repairs can take their toll on your company’s budget. Setup and reconfiguration require time and are usually a cause of disruption. This is not the case when you’re using hosted VoIP phone systems, with which deployment doesn’t take time and all updates and repairs are handled by the VoIP provider.


If your business has multiple locations, you need just as many hardware units and phone lines to ensure a certain level of service mobility. This is not a problem with VoIP, which allows you to make outbound calls and receive incoming calls from any device. It practically follows you wherever you go.

As long as there is an internet connection, the sales manager can contact field staff for an urgent task and a customer service rep working from home can easily address a complaint to avoid the customer’s ire. If you have to transfer a call to a colleague who’s working remotely, you don’t need to ask customers to call a different number.


So you’ve opened up a new location and need more phones for your employees. But how many will you actually use over the next year? You better estimate carefully so you don’t spend precious money on phone lines that’ll end up untouched.


There is definitely more to VoIP than just making or receiving calls. Apart from the basic features you get from traditional systems, modern VoIP systems can incorporate a host of other helpful communications tools, such as instant messaging, teleconferencing and video conferencing, virtual faxing, call recording, and more.

And yes, VoIP is capable of supporting fax through virtual faxing. It allows you to send and receive faxes without purchasing an actual machine and, by extension, paper and toner. All fax messages, as well as voicemails, can be forwarded to and stored in a single location.

Gather your employees anytime using the video conferencing feature if you have to discuss important issues. You may also use real-time team messaging if you have to simultaneously work on a task and get things done fast. All these work no matter where your employees are and whatever device they are using.

The above mentioned features are just some of the things that make VoIP such an efficiency booster for businesses of any type and size. Having access to advanced productivity tools allows workflows to be streamlined and empowers employees to multitask as the need arises.

Let’s say one of your sales agents is on a call within a queue. While waiting, he or she can browse through voicemail-to-text transcriptions from their email inbox or maybe archive or forward fax with the click of a mouse. You’ll be surprised to see the numerous features and a brand-new world of possibilities with a sophisticated VoIP phone service.


Integrating traditional phone systems with other systems your business uses is no easy task. In fact, it is incredibly difficult—as any company that’s experienced it could attest. With VoIP, this issue is nonexistent.

One of the things that make the adoption of VoIP technology appealing is the fact that it is capable of integrating with many business systems you and your employees are already familiar with, especially when you have phones that work with VoIP. As such, onboarding would be a cinch. This is possible because VoIP calls harness the power of the internet. For instance, an integration with Outlook® allows you to send and receive a fax or make outbound calls through that program.

Integrating business analytics is also relatively simple with VoIP. With actionable insights at your disposal, your business will be able to monitor and improve processes to further enhance your overall efficiency, connectivity, and productivity.


What if the internet in your area stops working? This is a common apprehension among business owners and managers who are considering switching to VoIP. They think that if the internet connection stops working, there is no way to make a voice call. Let's not even get started on traditional phones, which use cables and other hardware that can be compromised by fire or destroyed by an earthquake.

When disaster strikes or power goes out, your employees will have a hard time communicating with each other and customers won't be able to reach them. If you fail to recover quickly, you'll suffer a huge loss in terms of production and customer confidence and deal with regulatory fines.

Healthcare facilities, for example, need to abide by the provisions included in the Health Insurance Portability and Accountability Act (HIPAA). Otherwise, they could lose a huge amount of money on sanctions and penalties.

This is not a problem with a hosted VoIP phone system, which sits at a protected data center. It is monitored around the clock. So if something happens in your place of business, incoming calls will be forwarded to another location.

VoIP’s advanced call-forwarding functionality gives you the capacity to choose where and how your voice calls are forwarded so you don’t have to lose productivity in case of a disaster or a power outage. So even if it’s impossible to answer your office desk phone, you still have a secondary phone service like your laptop or smartphone you can use to communicate with collaborators and customers.


Frequently asked questions (FAQ) about VoIP services

What makes the best VoIP phone service is not only about facilitating calls over the internet. It is also about providing users with the best communications, through IP telephony, as possible. As an industry leader in unified communications, RingCentral is not just a means to call using an internet connection. They provide a seamless cloud communications solution where users can call, text, fax, live chat, and even host and join video meetings from one unified platform.


A typical hosted VoIP phone system generally costs between $20 and $45 per user. Of course, it will depend on the VoIP phone system features, capabilities, and the VoIP provider itself. You can check the RingCentral plans and pricing section above to see which plan fits your business needs. Whether you are a small business, a mid-sized business, or a big enterprise, you will find that RingCentral can seamlessly fit into how your organization operates. Plus, more than just a VoIP service that allows for unlimited calling across North America (US and CA), RingCentral offers an industry-leading unified communications solution that not only gives you a calling plan, but also provides you with a central hub for both communications and collaboration.


If you have employees that work away from the business’ home base, the top VoIP phone service for them would be the one that allows them to feel connected to the company even if they are not physically in the office. With the RingCentral App, telecommuting employees no longer have to use their home phones for work. Also, it provides your workforce with a central communications hub where team collaboration is encouraged through its various functionalities such as voice, fax, text messaging, live chat, and online meetings.


Any business can technically implement their own VoIP phone solution with the right combination of IT infrastructure to support VoIP technology and the skills and knowledge to make it happen. Unfortunately, the amount of capital investment needed to do that is staggering. Cloud communication service providers like RingCentral are able to offer businesses VoIP services with advanced features like cloud PBX, automated-attendant, answering rules, call forwarding, hold music, caller ID, call blocking, and more with flexible plans and pricing by hosting the services on their own secure, multi-tiered, and redundant cloud IT infrastructure and leveraging the internet for delivery of service.


There are direct-to-consumer VoIP services that do not require payment. WhatsApp, Viber, and even Facebook Messenger are basic mobile VoIP apps that facilitate calls over the Internet. These apps, however, are more for personal use and not suited for business communications. If you want to project a professional image, a VoIP phone system is the way to go, especially with its advanced features that are designed to help organizations communicate better with their customer base. It is not free, but RingCentral’s flexible VoIP plans and pricing will allow your business to have one bill to cover your communications needs with predictable fees and no surprise costs.


Most contact centers and call centers leverage VoIP technology as their telephony component because of its more affordable price when compared to traditional carriers. Aside from facilitating calls over the internet, VoIP is also used as the audio component for most video conference calling solutions. While there are other technologies at work for video calls and video conferencing, VoIP is usually the one responsible for allowing participants to actually talk with each other.


VoIP has paved the way for other means of leveraging the internet to send digital files over IP telephony transmissions. Virtual fax is one of those. While VoIP itself is not used to send fax over the internet, the concepts are pretty similar. The main difference is that the transmission is one way and the payload is a soft or hard copy of documents. The same goes for other modern systems that use IP transmissions like home security systems. Similar to virtual fax and VoIP, home security cameras use IP transmission to remotely transmit footage to cellphones and other streaming devices. The possibilities are virtually endless.
