Change is inevitable but what does it take for businesses to understand how modern technology will benefit their operations? An overview of the advantages and disadvantages of VoIP systems vs the traditional landline will give companies some understanding of how the shift towards Voice over IP is changing the face of telecommunications.

According to a study by Bebusinessed, small businesses that switch to VoIP reduce the cost of their local calls by up to 40%. In other words, cost savings are a significant factor in deciding between landline and VoIP. This trend also extends to household landlines, where a growing number of residences are opting for VoIP due to savings from the value bundles offered by VoIP providers.

What is VoIP?

VoIP uses a telephone set to transmit digitally converted audio signals over the internet. You can use the traditional phone - all you need is an internet connection and a VoIP adapter. Although the traditional landline is touted for its reliability, VoIP’s advantages extend beyond features offered by landlines, making the VoIP the technology of choice for future telecommunication services.


VoIP beats landline call costs on most occasions, with unlimited VoIP calls to the domestic market often included in a VoIP plan and international calls as low as 0.02 cents a minute. Voice over IP is definitely the sure bet when it comes to cost saving s VoIP providers don’t have the overheads of maintaining a traditional phone network. VoIP bills are often very similar month-to-month as opposed to landline bills which change depending on minutes over, features used, taxes applied and international calls made. So, when it comes to cost, VoIP has a heads up on landlines.


This is where landline creeps forward - but only slightly. If calls are made in bad weather or if there is a power outage, your call will drop out on a VoIP network. Landlines use a traditional phone line that doesn’t need a power server and is quite resistant to bad weather, while VoIP needs an internet connection and is vulnerable to dropping out. A robust internet connection is required when using VoIP, as dropouts from internet will render your VoIP system useless. While these days internet services are generally as reliable as a brand new Mercedes, the possibility of call drop outs still remains.

The features of VoIP extend beyond the traditional landline and, as the technology grows, more and more features are slowly being added to the service. Currently, the features of VoIP are in clear advantage against the traditional landlines.

Sound Quality

The difference in sound quality between the two technologies depends on a variety of factors. In the case of VoIP technology, the main factor is a robust internet connection. While the audio clarity of both systems is very similar on most occasions, digital internet sound quality has been producing crisper sound over the years. That’s not to say that VoIP clarity is ahead of its adversary on all occasions, but it does mean that it has the potential to creep forward as the analog technology of landlines becomes outdated. 4G mobile phones produce incredible clarity with sound, and VoIP can also produce unbelievable sound.  In the not too distant future, and with continuous improvements on VoIP networks, sound quality will go far beyond the quality offered by traditional landlines.


VoIP services have the potential to cross various systems, and your desktop is the most likely option from where to make VoIP calls these days. Also, calls can be made on a variety of applications on your computer, with cloud-based programs offering a simple migration of contacts from app to app.

To make VoIP calls you simply need a phone number and account, and with a VoIP adapter you can make calls from virtually anywhere, which is handy for business travel. And with the convenience of VoIP click-to-call, phone calls from your desktop are now easier than the click of a mouse. The use of a softphone dialer on your desktop also renders your VoIP just like a normal phone. VoIP is light years ahead of landlines when it comes to convenience and versatility, bringing a range of benefits and making it the first choice for businesses.

VoIP has an edge over landlines, and as internet technology becomes more robust, Voice over IP will provide an advantage in nearly all head-to-head comparisons. Cost savings are the most luring advantage for businesses, and with its versatility and convenience it’s obvious why more and more businesses are opting for the new technology. As the shift towards VoIP increases, the technology and savings will continue to grow due to competition, securing VoIP as the standard technology sooner rather than later.
