“In the past, telecommunication was all about landlines. Now, with the advent of voice-over-internet-protocol (VoIP), it has become possible for people to use the internet as their only means of communication. This has led to a lot of confusion for those who are using landlines and would love to switch to VoIP. In this article, we’ll look at VoIP vs. landline and explore their main differences, pros and cons, and identify the best option for your business.

VoIP vs. Landline: At a Glance 

The use of landlines has declined rapidly in the past few years since the rise of VoIP. Landlines offer voice communications over dedicated circuits via analog signals sent over copper wires, whereas VoIP uses IP packets to send data across the internet.

This development has given VoIP the edge as it possesses some clear advantages over landlines such as lower costs, increased flexibility, greater mobility and security. This type of phone service also has the ability to provide both traditional phone service as well as video calling.

What Is VoIP?

VoIP stands for voice-over-internet-protocol. It’s a technology that allows you to make phone calls (and other voice-based services) over the internet, rather than through a traditional landline phone system. This type of communication has become much easier since its introduction because of advances in broadband internet access, high-speed data networking equipment and software development.

VoIP services are cheaper than traditional landlines due to their low cost structure and reliance on data transmission rather than voice calls being made directly between two parties on either end of a line (as with landlines). You don’t have to pay for expensive dedicated lines or separate mobile phones.

With VoIP, you have the option to use your phone as a mobile device with calling features such as conference calls and video conferencing, or as a traditional landline for those times when you need to reach someone quickly at home on an emergency basis.

VoIP devices usually operate differently from traditional landline phones, including being able to send and receive faxes, text messages, instant messaging, web browsing and video streaming without having to dial out. Some VoIP providers even allow consumers to subscribe to unlimited calling plans at competitive rates.



  • Cost saving
  • More flexibility and portability
  • Offers better security
  • Includes more features such as SMS and instant messaging, voice mails and video calls
  • Power outages can prevent calls from working properly
  • It requires a good and steady internet connection
  • Latency and jitter issues can come up

What Is a Landline?

A landline phone is a telephone service provided through a dedicated line or system of wires and cables connected directly to the public switched telephone network (PSTN).

It’s a service that uses an analog telephone line. This explains its ability to convert sound waves into electrical waves, which are transferred through a network of copper wires. A landline is also referred to as a plain old telephone system (POTS). They are most commonly used in homes, but they’re also found in businesses, government buildings, hospitals and schools.



  • Does not require an internet connection
  • Easy to use and convenient
  • Ideal for emergency use
  • Great call quality
  • They can be very expensive
  • High cost of maintenance and installation
  • Prone to spam calls
  • Require physical installation

How Does VoIP Differ From a Landline?

There are many differences between VoIP and landlines. First, VoIP is internet-based, while landlines are analog. This means that you can use more than one device to connect to your phone line (such as an iPhone or Android phone) instead of just one device as with a landline.

Another difference is that voice calls made using VoIP are more secure than those made using a traditional home phone service because they’re transmitted over the internet rather than being routed through the public switched telephone network (PSTN). This means less chance for eavesdropping or interception as well as lower latency times when making calls via Wi-Fi networks or mobile data plans.

Which Is Best for Your Business: VoIP vs. Landline 

VoIP is a great choice for businesses that need to make long-distance calls. It’s also a good option for organizations that prefer group and conference calls for better collaboration and communication.

Landline is best suited for businesses located in places that have a bad or weak internet connection. It’s also a great backup for businesses using VoIP in times of emergencies (e.g., power outages caused by bad weather).

Trying to find the best fit for your business boils down to understanding the benefits and disadvantages with both options. Another key point here is the pricing. Traditional landline phone services cost more than VoIP due to the cost of infrastructure and maintenance. While a VoIP setup may cost around $800, that of landlines can go up to $2,500.”

As more businesses migrate to VoIP, those sticking with their old-fashioned landlines will find their bills increasing. This is because the providers are spreading the service and infrastructure maintenance cost over a dramatically shrinking customer base. Like death and taxes, your landline phone bill will continue to increase. Call us or visit our website to discuss the many options you have to take advantage of all VoIP offers.
