VoIP vs. Landline: Which Is Best for Your Business?

Wizix TechVoIP

Reliable communication is a key component of every successful business. However, copper phone lines are on their way out. Many businesses are transitioning from landlines to VoIP technology for its higher quality, better flexibility, lower cost, and many other advantages. 

Should your business make the switch? We compare VoIP vs. landline phone systems below to help you choose the best fit for your communication needs. 

What’s the Difference Between VoIP and Landlines?

VoIP stands for Voice over Internet Protocol, a type of phone system that allows you to make calls via an internet connection. On the other hand, landline phones traditionally use copper wires and switch boxes to connect calls. 

VoIP services can be accessed from anywhere with any device, but landlines cannot, because they need a physical connection to the phone network. In short, VoIP is digital, while landlines are analog. 

Pros and Cons of VoIP vs. Landline Phones

VoIP Pros

Connect From Anywhere

VoIP technology allows you to make phone calls from anywhere you have a good internet connection. Calls to a VoIP phone can even be re-routed to a mobile device, so your employees don’t have to be anchored to their office chairs to answer important customer calls. This flexibility makes it easier to run mobile businesses and manage hybrid or remote workforces

High Sound Quality

As long as you have a stable internet connection, you can expect clearer and more consistent sound quality with VoIP calls than with landlines. Landline phone calls are more prone to frustrating delays and annoying line noise such as static. 

Low Cost

VoIP phone systems are typically cheaper than landline systems, so you can support more phone lines and easily manage multiple locations. Plus, you won’t get charged for your call minutes or face extra fees on international calls. 


A VoIP phone system can easily grow along with your business because you can add or remove phone lines at any time. The system is also easy to set up, so your business can move to a new location anytime without issues or delays. 


When you have a strong internet connection, VoIP phones are very reliable. There’s no need to worry about interruptions caused by the bad weather or service outages that affect landlines. 

VoIP Cons

Limited by the Internet

The only drawback with VoIP technology is that you must have a stable internet connection for it to work. Otherwise, you might face dropped calls, static, and other issues. So if your business deals with slow internet speeds or spotty connectivity, then you may need to upgrade your internet plan, or stick with the landlines.

Landline Pros


Although landlines can sometimes experience outages, they are still quite reliable. You don’t have to worry about the strength of your internet connection in order for your call to go through. 

Landline Cons


Landline systems need a physical connection for every phone, which can lead to expensive installation costs. Adding extra features can also increase costs, while many affordable VoIP plans come with a variety of advanced features. Plus, you have to pay more for international calls on a landline. 


Landline phone systems are becoming a thing of the past. They are not flexible enough to keep up with the recent increase in remote workforces over the past few years, and are difficult and expensive to scale, so they have become outdated. In fact, copper-wire phone lines are actually being phased out because POTS lines are going away. If you must have a landline, you’ll need to look for a wireless solution.
