best VoIP

Voice over Internet Protocol (VoIP) is a technology that allows you to make voice calls using a broadband Internet connection instead of a regular (or analog) phone line. The rapid growth in remote work, global collaboration, and digital transformation has catapulted VoIP technology into an indispensable part of both personal and business phone systems. With flexibility, cost-efficiency, and a broad range of features, VoIP stands at the core of modern communication needs in 2023.

This comprehensive article aims to be your one-stop guide to understanding VoIP in 2023. We’ll delve into what VoIP is, its history, advantages, and disadvantages, how to choose a business phone system, and review some of the best VoIP services available this year.

Understanding VoIP

What is VoIP?

VoIP stands for Voice over Internet Protocol. It is a technology that converts your voice into a digital signal, allowing you to make a call directly from a computer, VoIP phone, or other data-driven devices. Simply put, it’s phone service delivered over the internet.

How It Works

When you place a VoIP call, your voice is converted into packets of data. These packets are sent through your Internet connection to the recipient on the other end, where they are converted back into sound. Because the data travels over the Internet, VoIP services can provide a wide range of additional features like text, video, and even virtual meetings alongside voice calling.

History of VoIP

The concept of VoIP started as early as the 1970s, long before the internet was a household name. Originally it was a method developed by researchers to transmit voice data over Arpanet, the precursor to the internet. The initial VoIP technologies were clunky, and the voice quality was often poor and unreliable.

As the Internet gained more widespread adoption, VoIP technologies also evolved significantly. With the advent of DSL and broadband, VoIP’s call quality improved dramatically. The late 1990s and early 2000s saw the rise of early VoIP services, but it wasn’t until the last decade that VoIP truly came into its own. Today, the technology supports rich, high-definition audio and video calls, along with a multitude of features like call forwarding, SMS, video conferencing, and more.

By now, VoIP isn’t just an alternative to traditional phone lines—it has largely replaced them, especially in business settings. The industry has seen a boom in cloud-based VoIP services, making it easier and more affordable than ever to switch to VoIP solutions.


Types of Business VoIP Service

Residential VoIP

Residential VoIP services replace your traditional landline phone service, using your home’s existing broadband internet connection to make and receive calls. They often come packed with features like voicemail, caller ID, and even international calling options, all usually at a lower price point than traditional phone services.

Business VoIP

Business VoIP solutions are more complex and designed to serve multiple phone lines within an organization. These systems often include a range of features necessary for business operations like auto-attendants, call forwarding, voicemail-to-email, and more. Cloud-based options make it easier than ever for businesses to scale their communication systems in line with their growth.

Wholesale VoIP

Wholesale VoIP is a service that is sold in bulk volumes to service providers who have the customer base to leverage it. This enables these companies to provide low-cost solutions to end-users and smaller VoIP providers. Wholesale VoIP can include anything from hosted VoIP services to basic software solutions and features.

Advantages and Disadvantages

Advantages of VoIP

  1. Cost-Efficiency: One of the most significant advantages of VoIP is its cost-efficiency. Whether it’s domestic or international calls, VoIP services are generally cheaper than traditional telephone services.
  2. Versatility: VoIP is not just about voice calls. Modern VoIP services offer a range of features including video conferencing, SMS, and more.
  3. Portability: As long as you have an internet connection, you can use your VoIP system anywhere, making it ideal for remote work and global operations.

  5. Quality: With a good internet connection, the call quality is often better than that of a traditional phone line.

Disadvantages of VoIP

  2. Quality Concerns: While VoIP quality can be excellent, it can also be affected by bandwidth limitations or network congestion.
  3. Security Risks: Like any internet-connected system, VoIP is susceptible to hacking and other cyber threats.
  4. Initial Costs: Some VoIP systems may require specialized hardware or initial set-up fees, though these are usually offset by long-term savings.
  5. Regulatory and Compliance Concerns: Particularly for businesses, ensuring a VoIP system is compliant with local and international communication laws can be challenging.

  3. Technical Requirements: Make sure that you won’t have to overhaul your entire system to scale up in the future.

Pricing Models


The freemium model offers basic VoIP services for free, while more advanced features and capabilities are locked behind a paywall. This is a popular model for individual users and small businesses looking to try out a VoIP service without immediate financial commitment.

Google Voice and Skype offer freemium services where users can make free calls, send texts, and access basic VoIP functionalities. Additional business-focused features require upgrading to a paid plan.


The subscription-based pricing model involves paying a fixed monthly or yearly fee for VoIP services. This is most commonly used by businesses and offers a range of features like call analytics, auto-attendants, and integrations with other software.

RingCentral, 8×8, and Ooma are examples of VoIP providers that offer subscription-based pricing.


In a pay-as-you-go model, you are charged based on the actual usage of services rather than a fixed monthly fee. This is beneficial for businesses with fluctuating communication needs.

Some niche VoIP providers and wholesale VoIP services use a pay-as-you-go pricing model, charging for the actual minutes used or the number of calls made.

Multi-line Support

Multi-line support enables multiple calls on the same device, either through additional physical lines or virtual lines. This feature is crucial for businesses that need to manage multiple simultaneous calls, such as customer service centers or busy offices.

Technical Requirements: VoIP Phone Service

Internet Speed

A reliable and fast internet connection is crucial for high-quality VoIP calls. For a single VoIP phone call, you might need between 85 to 100 Kbps of bandwidth, but this can vary based on the codec your VoIP provider uses.

Insufficient internet speed can lead to dropped calls, delays, or poor audio quality. For businesses with multiple employees making simultaneous calls, a fast and stable internet connection is even more critical.

Hardware Requirements

Basic hardware requirements for a VoIP setup typically include a VoIP-enabled phone, a computer, or a mobile device. Some setups may also require additional hardware like an Analog Telephone Adapter (ATA) or a VoIP router.

Investing in quality hardware ensures better call quality and fewer technical issues down the line. Some VoIP services might offer proprietary hardware that is optimized for their network, which can enhance performance.

Software Compatibility

Your VoIP provider will usually offer software that needs to be installed on your device(s). Make sure that this software is compatible with your operating system. Also, you may need to check compatibility with other software tools your business uses, like CRM systems.

Software compatibility ensures a seamless integration of the VoIP system into your existing workflow. It enables features like click-to-call from your CRM, easy importing of contacts, and more.

Legal and Regulatory Concerns: Business VoIP service

Data Privacy

Data privacy is a significant concern when implementing VoIP, especially when calls are being recorded. Make sure your provider complies with regulations like the GDPR if you’re operating in Europe or HIPAA if you’re in healthcare in the United States. Failing to comply with data privacy laws can lead to hefty fines and legal actions.


Beyond data privacy, business phone systems must adhere to various industry-specific regulations. For example, financial services companies might have to comply with SOX, while healthcare organizations need to consider HIPAA regulations. Non-compliance can not only result in financial penalties but also erode trust between you and your clients.

International Use

Country-Specific Restrictions

VoIP services are not uniformly available worldwide. Certain countries have restrictions or have outright banned the use of VoIP services for various reasons including regulatory issues or to protect the interests of local telecom providers.

Before implementing VoIP in your international offices or for overseas communication, it’s crucial to check the legal status of VoIP in the specific countries you’ll be operating in.

Best Business VoIP Providers for International Calls

When your business involves a lot of international communication, look for providers that offer cost-effective international rates, high-quality calls, and the availability of local numbers.


  • RingCentral offers global office features.
  • Skype for Business is widely used for international calls.
  • Vonage offers competitive international rates.

Security Features


Encryption converts your voice into complex codes as it travels across the internet, only to be decoded once it reaches its final destination. This is crucial for preventing eavesdropping and ensuring the confidentiality of your communications.

In today’s digital age, data breaches are increasingly common, and voice data is no exception. Encryption adds an extra layer of security, making it difficult for unauthorized users to access your conversations.

Two-Factor Authentication

Two-Factor Authentication (2FA) adds an extra step of verification, commonly through a mobile device or email, to ensure that you’re the only person who can access your VoIP account.

2FA provides an additional layer of security that protects you even if your password is compromised, making it increasingly difficult for unauthorized users to gain control over your VoIP services.

2-factor authentication

Troubleshooting Common Issues

Call Drop

One of the most frustrating issues where the call disconnects abruptly.


  1. Check Internet Connection: Unstable internet is the most common cause. Ensure your internet connection is stable and fast enough for VoIP.
  2. Upgrade Firmware: Sometimes outdated hardware can cause issues. Make sure your hardware is up-to-date.


Hearing your voice echo during a call.


  1. Adjust Volume: Sometimes reducing the volume can minimize the echo.
  2. Headset Use: Using a headset instead of speakers can eliminate echo.

Poor Call Quality

Experiencing unclear audio, or the call breaking up.


  1. Check Bandwidth: Insufficient bandwidth can result in poor call quality. Run a speed test to confirm.
  2. Disable Other Devices: Sometimes other devices on the same network can consume bandwidth. Make sure you prioritize your VoIP service.


A lag between when you speak and when the other person hears you, or vice versa.


  1. Upgrade Network Infrastructure: Outdated routers or modems can cause delays.
  2. Quality of Service Settings: Use QoS settings to prioritize VoIP traffic over other types.

No Dial Tone

You can’t make outgoing calls because there’s no dial tone.


  1. Check Hardware: Sometimes the issue could be as simple as a disconnected cable.
  2. Reboot the System: If hardware seems fine, try rebooting the VoIP system.

Unable to Receive Calls

Incoming calls are not reaching you.

Q: Is VoIP Reliable?

VoIP has come a long way in terms of reliability. Early versions were dependent on the stability and speed of your internet connection. While that’s still a factor, advancements in technology have made VoIP nearly as reliable as traditional phone lines. Some enterprises even consider it more reliable due to features like cloud failover and geo-redundancy. However, the reliability can vary between providers, so it’s crucial to choose a reputable one.

Q: Can I Keep My Phone Number?

Yes, most VoIP providers offer a feature known as number porting, which allows you to keep your existing phone number. It usually takes a few days to a week for the porting process to complete. It’s best to check with your chosen provider for specific details and to ensure that number porting is supported in your geographical area.

Q: Is VoIP Secure?

VoIP can be as secure as you make it. Most reputable providers offer robust security features, including end-to-end encryption and secure data centers. However, like any online service, VoIP is vulnerable to hacking if not adequately secured. Utilizing strong, unique passwords and enabling two-factor authentication are some of the ways you can enhance security.

Q: How is the Call Quality?

A: The call quality on VoIP services is generally excellent and, in some cases, even surpasses traditional phone lines. VoIP technology has improved significantly over the years, offering crystal clear voice quality. However, the call quality can vary based on several factors, such as your internet speed, the quality of your hardware, and the VoIP provider you choose. Most providers offer HD Voice features, but it’s always a good idea to do a test run before making a commitment.
