In this article, we’ll compare VoIP Vs. Landlines and guide you toward the best phone system for your business needs. Let’s dive in!


  • VoIP and landlines differ in various aspects, including mode of communication, cost, and mobility.
  • VoIP phone systems use the Internet to make and receive calls, while landlines use copper wire to communicate.
  • VoIP offers flexibility, portability, and cost-effectiveness, making it a clear winner over landlines.

What is VoIP?

What is Voip

Voice over Internet Protocol (VoIP) is a phone system that uses the Internet to receive and make calls instead of traditional landlines. It turns the sound of your voice into digital data that is then sent over the Internet.

You can use your computer, smartphone, or other mobile devices to make VoIP calls. As Internet access has become more common, VoIP has become a popular personal and business communication choice.

Pros of VoIP

Some of the benefits of using VoIP include:

  1. Budget-friendly

One of VoIP’s main advantages is its budget-friendliness. It eliminates the need for different equipment, expensive wiring, and more. Also, direct calling via the Internet reduces expenses compared to traditional landline phone providers, lowering monthly costs.

  1. Flexibility

VoIP allows users to work from anywhere with internet access. Remote work becomes more manageable with VoIP communication solutions in place. Also, VoIP enables you to make and receive calls from any device, like computers, laptops, and mobile phones, giving you more flexibility.

  1. Easy to Manage and Set up

You might have faced lots of hassle while setting up a traditional phone system in your company. All those wires and maintenance from time to time can be frustrating to anyone.

However, in the case of VoIP, all you need to do is download an app or contact a VoIP service provider like KrispCall. After that, you can start using VoIP service. That way, you can easily install, configure, and maintain it, even without the help of a professional’s technical support. 

  1. Higher Scalability

One of the great things about VoIP is that it is highly scalable. You can add or remove phone lines, extensions, features, and users whenever you want. Also, with VoIP’s virtual phone system, you don’t need to invest in expensive hardware or new phone lines as a business phone system expands.

Cons of VoIP

As there are a lot of advantages to using VoIP service, there are also some disadvantages of

using this new technology.

  1. Dependence on the Internet

VoIP relies entirely on Internet connectivity. Any disruption to the internet service interrupts VoIP communication, making it unavailable during instances such as electricity outages. Also, VoIP users require a stable and high-speed internet connection to ensure proper communication quality. Slow internet speeds or unreliable Wi-Fi can reduce call quality and disruptions during conversation.

  1. Power needs

To operate, your modem, router, ATA, and other VoIP equipment must be connected to an electrical power source. If you experience a power outage, your phone service will also be affected. Even with a UPS (uninterruptible power supply), the backup power will only last for a brief period, offering limited assistance.

  1. Security problem

Another major setback of VoIP is security issues. Since VoIP data travels over the Internet, there can be identity theft, virus malware, denial of service, spam, call tampering, and phishing attacks. Many attackers may attempt to steal user identities, hijack VoIP services, gain unauthorized access to call data or use someone else’s account for malicious purposes.

  1. Emergency call limitation

Whenever someone calls for emergency help, it’s important to know where they are so that responders can get there quickly. However, since the VoIP phone system isn’t associated with a specific location, calls can originate from anywhere with an internet connection. Hence, it becomes difficult for emergency personnel to figure out where you are exactly located.

What is Landline?

What is Landline

A landline is a traditional phone system that sends voice signals through physical wire. It uses copper wiring or fiber optic cable to transmit voice audio from one phone to another.

A traditional landline phone’s wire is connected directly to the public switched telephone network (PSTN), which allows users to communicate through voice. Moreover, Landline phone systems are analog phone systems installed by the local phone company. They’re also known as Plain Old Telephone Service (POTS). 

Pros of Landline

Here are some advantages of using a landline: 

  1. Excellent call quality

As we all know, a landline uses wires to transmit signals. The physical connection provided by wires offers more consistent and reliable voice signal transmission than internet-based systems, which results in more precise audio quality.

  1. Best for emergency use

Even though we barely use landlines to make calls these days, they can be the best option in emergencies. They are linked to a specific address that helps medical personnel find your location. Also, you can still use a landline if there is a power outage, as it doesn’t need internet or recharge. 

  1. Doesn’t rely on the Internet

VoIP entirely relies on the Internet, so if the Internet is down, VoIP doesn’t work. This is not the case with Traditional landlines, as they have a completely different system. They simply rely on a wire and PBX system.

  1. Better security

Landline phones provide more security than VoIP cell phones as they don’t use wireless signals to communicate. In fact, the call is transferred through a wire cable, which is much more secure than VoIP. 

Cons of Landline

These are some of the cons you encounter when dealing with landlines:

  1. Expensive

Landline phones are much more expensive than VoIP phone systems. A landline system uses various equipment, such as wire, box, and system, which can be costly. In addition, landline phone service can be more expensive, especially when calling long distance. Plus, the cost of a monthly subscription is increasing daily.

  1. Limited feature

Landline phones have limited call management features compared to VoIP. They lack several features, such as call forwarding, call transferring, IVR, call routing, or call queuing, which are essential to handling calls effectively. 

  1. Dependency on infrastructure

As VoIP depends on the internet, a landline relies on infrastructure like wire and cable. Various sources, including natural disasters like earthquakes, hurricanes, floods, accidents, etc., can easily damage traditional landline systems’ wires and cables.

  1. Less flexibility

Landline phones are designed to be installed and set up in only one location. That means they can only be used near their connection point. Moreover, relocating landline phones can be extremely frustrating when users change residences or office locations.

Key Difference between VoIP Vs. Landline for business

key difference between VoIP Vs Landline for business

Although landlines and VoIP serve the same purpose: to allow users to connect with anyone via phone calls whenever they want, they differ in several aspects. These aspects include:

1. Method of Communication

The most apparent difference between VoIP and landline is their method of communicating. VoIP uses the Internet to make and receive calls. On the other hand, landlines use copper wire to communicate. This means that VoIP calls can be made anywhere with an internet connection, while landline calls are restricted to some geographical regions.

Likewise, VoIP converts your voice into digital data packets and sends them over the Internet. In contrast, landlines send voice signals through a physical wire.

2. Cost

Another significant difference is its cost. With landlines, you often have to pay a lot upfront for setting everything up, like installing phone lines and getting equipment. On the other hand, VoIP systems usually need less setup and equipment since they use the internet.

Also, monthly fees for landlines can add up, especially with long-distance calls and extra features like voicemail. VoIP services often offer affordable monthly rates, including many features and cheaper long-distance calls. 

VoIP systems also need less maintenance and are easier to expand if your business grows. So, overall, VoIP can be cheaper and more flexible than traditional landline phones.

3. Mobility

VoIP offers higher mobility compared to traditional phones. Landline phones are fixed in one location/place. That means you can’t take them when you leave that location.

In contrast, since VoIP operates over WIFI, you can make and receive calls from anywhere, whether at the office or home, as long as you have internet access. You’re not tied down to a specific location like you are with landline phones.

Which Phone system is best for Businesses?
