VoIP Phone Service - How It Works for Your Business
Work Anywhere. Productivity has no limits.
What is VoIP?
A brief introduction to Voice over Internet Protocol.
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 connections, it allows anyone to use Voice over IP from anywhere via their laptops, desktops, or smart devices.

Frequently asked questions (FAQ) about business meeting apps
What is the best VoIP phone service?
What makes the best VoIP phone service is not only about facilitating calls over the internet. It is also about providing users the best communications experience possible. As an industry leader in unified communications, RingCentral is not just a means to call over the internet. 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.
How much does VoIP service cost?
A typical hosted VoIP phone system generally cost between $20 and $45 per user. Of course, it will depend on the 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 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), RingCental 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.
What is the best VoIP service for home-based and telecommuting employees?
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 a central communications hub where team collaboration is encouraged through voice, fax, text messaging, live chat, and even online meetings.
Does VoIP require a service provider?
Any business can technically implement their own VoIP phone solution with the right combination of IT infrastructure to support it and the skills and knowledge to make it happen. Unfortunately, the amount of capital investment needed to do that is staggering. Cloud communication 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.
Is there a free VoIP 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.
What is VoIP used for?
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.
Can VoIP be used for Fax?
VoIP has paved the way for other means of leveraging the internet to send digital files over IP 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.
How VoIP Works
VoIP and Internet Telephony Basics: Important terms and concepts
Voice over Internet Protocol is a set of protocols working together to provide telephony service that’s similar to regular landlines.
Before we go over the end-to-end process of how Voice over IP works, it is important that you familiarize yourself with some basic concepts that will help you understand how the technology works as a whole.
IP Packets for VoIP Transmission
Voice and data are encapsulated here. During a VoIP call, the voice or audio is captured and segmented into tiny samples which are then carried as payloads. These samples are attached to IP packets that will be transmitted between different networks, both public and private.
Codecs for conversion of analog voice data
Also known as codec-decoder, it converts analog voice signals (like your voice) into digital voice formats that are ready to be transmitted over the Internet. It also converts the digital form back to analog for the human ear.
Transmission Control Protocol (TCP) vs. User Datagram Protocol (UDP) for VoIP delivery
These are the two most common methods for delivering VoIP protocols over the Internet.
- TCP-IP: packets sent using this method guarantees that data is delivered; and if it’s lost, it will be transmitted. Think quality over speed.
- UDP-IP: packets are sent over the networks with no guarantee it will be received. Think speed over quality.
Real-time Transport Protocol (RTP) for carrying VoIP audio stream
This protocol is responsible for carrying audio and video streams during VoIP transmissions. It carries the information about the file, including its format and media type.
Session Initiated Protocol (SIP) and SIP Servers for VoIP signaling
SIP is the protocol that is responsible for mimicking regular telephony. It is a standard signaling protocol that establishes, manages, and terminates real-time communications over IP networks.
SIP servers, on the other hand, accept SIP requests and respond to them. There are many types of SIP servers, with the Proxy server being the most known (since it facilitates connections to establish Voice over IP). Other SIP servers include Registration Server, Presence Server, and Redirect Server.
End-to-end process of VoIP
Using what we learned, here is an example of how a VoIP call works, with each step showing what is going on in the background for every action taken.
- Person A calls Person B (the calling party uses the SIP signal to try to establish a connection via the Proxy server--RingCentral uses TCP to deliver SIP)
- Person B answers the call (the called party accepts the request from Proxy Server using SIP)
- Person A and Person B talk (IP packet containing voice data is delivered via UDP or TCP; RTP transmits the voice data, while Codecs convert analog voice to digital format and vice-versa. All these are happening in real-time.)
- Person A or Person B ends the call (the SIP signal is used to terminate the connection)
Making VoIP calls to regular phone lines or PSTN through VoIP gateways
VoIP gateways are used to convert traditional telephony connections into VoIP connections and vice-versa.
What happens is that when calls are initiated from a traditional landline phone, the gateway will translate the multiplexed voice into packetized voice sample. It will then follow the same call process discussed above.
While there’s more to hosted VoIP transmissions than what is discussed here, this should give you a general idea of how the technology works.
How to Choose the Right Business VoIP Provider
Prices don’t always define a good VoIP phone service
While cost is always a factor when considering a provider or supplier, it should not be the be-all and end-all of your decision-making.
Take VoIP phone providers, for example. If you choose the cheapest provider for your business communications, there’s a good chance that you will also get the cheapest call quality.
In the end, it can lead to damaged customer relationships which will eventually lead to lost money.
That is why it is important to look at each offering to see if they are worth the price they are charging.
To help you out, here are some factors you should consider when choosing a Voice over IP provider:
Reputable VoIP service providers do not neglect security and reliability
The first thing you should consider when choosing a VoIP provider is security and reliability. Would they be able to keep the service up at all times? Would they be able to protect your calls and other data during transmissions?
RingCentral hosts its virtual phone system in multiple data centers to ensure redundancy and keep their service up at all times. It also employs several security measures like encryption, data center audits, multi-factor authentication, and advanced account administration to protect the system and its users.
Top-tier internet telephone systems are loaded with features
Most VoIP services for business are attached to a more comprehensive phone system, which is equipped with different call features to help you manage your calls. In some cases, providers require their subscribers to pay extra for premium features to be included in their packages.
RingCentral, though, offers more than that. Its VoIP services provide not only a business phone system for calling and managing incoming calls, but actually delivers a unified communications solution that also includes team collaboration and HD video meetings in one platform with no separate billings.
Superior customer support is a must for VoIP phone service providers
Most think of customer support as something that happens when something went wrong. While that is true, customer support is more than that.
Customer support is about assisting customers not only when there is something wrong, but also to prevent major issues. That is why true customer service starts when a customer subscribes.
RingCentral is with you from day one, assisting you in setting up and configuring the VoIP system to your own network. After which, its award-winning customer service is available for technical support, consultations, and best-practice recommendations.
Exceptional VoIP phone services mean high trust ratings
Good VoIP companies have a reputation for excellent service. To evaluate this, you can look at trust indicators like positive reviews of the company.
RingCentral, as the industry leader in cloud communications, is trusted by more than 350,000 businesses across the country. You can look at the different success stories through testimonials and case studies from actual businesses.
There is more to choosing a VoIP provider than just looking at price. Look at these factors and carefully weigh your options before deciding on the top VoIP phone company on your list.
