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 call directly from a computer or mobile device, 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 data packets. These packets are sent through your reliable 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 in an Android mobile phone.

History of VoIP

The concept of VoIP started as early as the 1970s, long before the Internet was a household name. Initially, researchers developed a method to transmit voice data over Arpanet, the precursor to the Internet. The initial VoIP technologies were clunky, and the voice quality could have been better and more reliable.

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 in the last decade, VoIP came into its own. Today, the technology supports rich, high-definition audio and video calls and features like 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 switching to VoIP solutions more accessible and affordable than ever.

Check out our PBX and VoIP comparison here.


Different Types of Business VoIP Services

Residential VoIP

Residential VoIP replaces your traditional landline phone service, using your home’s existing internet connection (broadband) 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 than traditional phone and mobile phone services.

Business VoIP

Business VoIP services or VoIP solutions are more complex and designed to serve multiple phone lines within an organization. These business VoIP phone systems often include various features necessary for business operations, like auto-attendants, forwarding, voicemail-to-email, and more. 

Cloud-based options make it easier for businesses to scale their phone systems in line with their growth even without a mobile phone.

Wholesale VoIP

Wholesale VoIP is a service sold in bulk volumes to service providers with the customer base to leverage it. It enables these companies to provide low-cost solutions to end-users and smaller VoIP providers.

Wholesale VoIP can include anything from hosted VoIP phone services to basic software solutions and features.

Advantages & Disadvantages 

Advantages of VoIP

  1. Cost-Efficiency: One of the most significant advantages of VoIP is its cost-efficiency. Whether domestic or international VoIP calls, VoIP services are generally cheaper than traditional telephone services.
  2. Versatility: VoIP is about more than just 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.
  4. Scalability: Businesses can easily add or remove lines and services based on their needs. Cloud-based solutions make it particularly easy to scale.
  5. Quality: With a good internet connection, the quality is often better than a traditional phone line.
  6. Integration: VoIP systems can often be integrated with other business systems like CRM software, providing a seamless communication experience.

Disadvantages of VoIP

  1. Dependence on Internet Connection: Because VoIP relies on an internet connection, you lose your phone service if you lose connectivity.
  2. Quality Concerns: While VoIP quality can be excellent, it can also be affected by bandwidth limitations or network congestion.
  3. Security Risks: VoIP is susceptible to hacking and other cyber threats like any internet-connected system.
  4. Initial Costs: Some VoIP systems may require specialized hardware or initial setup fees, though long-term savings usually offset these.
  5. Regulatory and Compliance Concerns: Particularly for businesses, ensuring a VoIP system is compliant with local and international communication laws can be challenging.

Criteria for Evaluation

When selecting the best VoIP service for your needs, it’s essential to consider various factors that contribute to your communication strategy’s short-term and long-term success. Below are some fundamental criteria that should be part of your evaluation process:


  1. Uptime: Look for services that guarantee at least 99.9% uptime.
  2. Redundancy: Check if the VoIP service provider has redundant data centers to handle failures effectively.
  3. Emergency Services: Ensure the VoIP phone service provides reliable 911 and phone support.
  4. Failover Options: Make sure there are options for call rerouting and phone support in case of internet failures.

Quality of Service (QoS)

  1. Call Quality: Test the call quality to ensure it meets your standards.
  2. Low Latency: The lower the latency, the better the voice quality.
  3. Bandwidth Requirements: Ensure the VoIP service’s bandwidth requirements align with your setup.
  4. HD Voice: Consider if HD voice is a feature required for clear business voice communications.


  1. Setup Costs: Look at any initial setup costs, including hardware.
  2. Monthly Fees: Examine the monthly fees and the features included in that price.
  3. International Rates: If you make many international phone calls, check the rates and confirm if they differ if you receive calls, too.
  4. Hidden Fees: Always read the fine print to check for hidden fees like extra features or early termination charges. Always confirm if it comes with unlimited calling, works on desktop and mobile devices, and audio conferencing to avoid hidden fees.


  1. Basic Features: Ensure that fundamental features like call forwarding, voicemail, and caller ID are included.
  2. Advanced Features: Check for availability of advanced features like video conferencing, automated attendants, and integrations with other software.
  3. Customizability: See if the service allows you to customize features to fit your needs.

  1. Ease of Adding Lines/Features: Ensure it’s easy to add or remove lines or features as your needs change.
  2. Plans: Check if there are plans designed to grow your Business. Also, consider plans with outbound calls, unlimited calling, and private branch exchange.
  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 essential 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 enterprises looking to try 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. Businesses most commonly use this and offer 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, VoIP service providers will be charged based on service usage 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.

Must-Have Features: Business VoIP Systems

Call Forwarding

Call forwarding allows incoming calls to be rerouted to another phone number, temporarily or permanently. It ensures that you get all the important calls, even when you’re not near your office phone.

For businesses, the ability to forward calls to mobiles, landlines, or even international numbers ensures that employees are always reachable. It’s especially beneficial for remote or traveling staff.


This feature sends a copy of your voicemails to your email account as an audio file or transcribed text. Voicemail-to-email ensures you get all the important messages and allows you to respond more promptly. It also makes it easier to archive or forward messages.

Call Recording

Using the best VoIP telephone service, you can record telephone conversations for later review, either manually or automatically. Call recording is crucial for quality control, training, and legal compliance. For these reasons, many businesses require the ability to record customer interactions.


An auto-attendant is a virtual receptionist who greets callers and directs them to the appropriate extension or department. An auto-attendant adds professionalism to your operations and helps manage high call volumes. It can also reduce the need for a full-time receptionist.

Business VoIP Systems

Optional Features: Business VoIP Service

Video Conferencing

The ability to hold virtual meetings through video calls is often integrated into the VoIP system. Video conferencing enables remote collaboration and adds a personal touch to meetings, making conveying complex ideas easier and fostering team connections.

Chat Support

This feature allows for text-based business communications within your organization or with customers. Chat support is excellent for quick business communications, multitasking, and a record of interactions. It’s particularly beneficial for customer support teams.

Multi-line Support

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

Technical Requirements: Best VoIP Phone Service

Internet Speed

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

There must be more internet speed to avoid dropped calls, delays, or poor audio quality. A fast and stable internet connection is even more critical for businesses with multiple employees making simultaneous calls.

Hardware Requirements

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

Investing in quality hardware ensures better IP telephony quality and fewer technical issues down the line. Some VoIP services offer proprietary hardware 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, check compatibility with your Business’s software tools, 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 contact import, and more.

Industry Applications


VoIP solutions are becoming an integral part of healthcare communication systems. They facilitate smooth patient-doctor interactions, administrative communication, and emergency responses.

Some of the critical features of VoIP phone systems used in healthcare would be:

  • Secure Video Conferencing for telehealth sessions
  • Call Recording for legal documentation
  • Voicemail-to-Email for better message management


VoIP in educational institutions enables smoother communication among teachers, students, and parents. It’s beneficial for distance learning and virtual classrooms.

Some of the key features of VoIP service used in retail are:

  • Call Forwarding to route customer calls to the suitable agents
  • Call Recording for quality assurance
  • Video Conferencing for virtual team meetings

Legal & Regulatory Concerns: Business VoIP service

Data Privacy

Data privacy is a significant concern when implementing VoIP, mainly when calls are recorded. Ensure 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 result in financial penalties and erode trust between you and your clients.

International Use

Country-Specific Restrictions

VoIP services are not uniformly available worldwide. Certain countries have restrictions or outright banned 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 hosted VoIP 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. It is crucial for preventing eavesdropping and ensuring the confidentiality of your business communications and VoIP calls.

In today’s digital age, data breaches are increasingly common, and voice data is no exception, so investing in the best VoIP providers can be a great solution. 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 verification step, commonly through a mobile device or email, to ensure 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 is when the call disconnects abruptly.


  1. Check Internet Connection: An unstable internet connection 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: Other devices on the same network can sometimes consume bandwidth. Make sure you prioritize your VoIP service.


There is 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 the hardware seems fine, try rebooting the VoIP system.

Unable to Receive Calls

Incoming calls are not reaching you.


  1. Check Settings: Incorrect settings can often direct calls to voicemail. Make sure your settings are correct.
  2. Firewall Issues: Sometimes, firewall settings can prevent incoming calls. Check your firewall settings to make sure VoIP traffic is allowed.

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, technological advancements have made VoIP nearly as reliable as traditional phone lines.

Some enterprises even consider it more reliable due to features like cloud PBX failover and geo-redundancy. However, the reliability can vary between providers, so choosing a reputable one is crucial.

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.

When choosing the best VoIP provider, check for specific details and ensure that number porting is supported in your geographical area.

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.

How is the call quality?

The call quality on VoIP services is generally excellent and, in some cases, even surpasses traditional phone lines. VoIP technology has improved significantly, 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 doing a test run before committing is always a good idea.

The VoIP landscape has significantly evolved, offering many options for small and large businesses.
