How Does the Call Quality of a VoIP phone compare to a Landline?

VoIP technology has been around for many years but has recently seen a massive rise in its popularity amongst businesses, mostly due to its mobility and versatility, which can be invaluable to many teams right now.  Many people still have reservations about VoIP though, and this is understandable.  A large amount of us were introduced to VoIP via Skype’s free call and video service in the mid-2000s, and whilst that service was free and helpful, its call quality wasn’t anything to write home about.

Fast forward to 2020 and businesses are embracing VoIP technology more and more but concerns about audio and video quality still remain.  Thankfully, the technology has caught up with the times and there are VoIP services, especially for businesses, that can easily compete with landline phones in terms of call quality whilst maintaining the other benefits of VoIP.  Still, many businesses have not fully optimised their phone system and are maybe not getting as much out of VoIP as they can.  With that in mind, here is a quick guide on how to get the best audio quality out of your business’ VoIP phone system, compared to a landline.


Check Your Internet Connection

One of the biggest advantages of a landline phone is that it operates over a system that was designed exclusively for voice communication.  Because of this they have a quite a big head-start over any technology trying to compete with them when it comes to audio quality. VoIP on the other hand operates over the internet and so it is dependent on how good a signal you have.  Thankfully, internet speeds have come on in leaps and bounds in recent years just as VoIP has.  The aim with VoIP is to be able to communicate without the receiving party even knowing that the call is taking place over the internet, and as long as you have a good connection this happens most of the time.

If your business is struggling with its internet connection, consider investing in your business broadband service.  Modern business broadband can prioritise your business’ Wi-Fi over other traffic in your area, allowing you to maintain a consistently reliable connection.  The arrival of the 5G network is also expected to greatly reduce latency, so that you can communicate effectively with VoIP, even when you’re not in the office.


Choose the Right Hardware

Like all technology, when choosing the right phone system for your business making sure you have the proper hardware is very important.  The vast majority of landline phones come with cheap microphones and speakers, this older technology often leads to audio quality that can sound faint or grainy.  VoIP systems can be upgraded by investing in headsets that offer much clearer sound, so you have the ability to fully equip your team with professional sounding audio at all times.

Equipping your team with the right tools can enhance your VoIP system so that it goes toe to toe with landline on audio quality, whilst also offering a greater range of functionality.



When it comes to VoIP’s call quality there are a few things that could negatively affect your experience, but these are relatively easy to fix.  Occasionally you may experience interference due to your phones operating over the same frequency.  Similarly, if your VoIP adapter is next to your router you might also hear some feedback or static, but this can all be fixed easily by moving your devices around.

Landlines do not run into these issues and their call quality is also unaffected by external factors such as bad weather or power outages.  Landlines however, are let down by their inflexibility.  If you need to install new phones or change your network in any way, landline systems can experience a large amount of downtime and become completely inaccessible.


Overall, modern VoIP technology is able to go toe to toe with their landline counterparts in terms of call quality.  On the whole customers can rarely tell the difference between the two services, and any issues you do find with VoIP are easy to fix.  As long as your business is equipped with suitable hardware and has a reliable internet connection then VoIP is an effective and versatile communication service for businesses.

This isn’t even to mention the other benefits of VoIP technology, from facilitating remote working to being completely scalable as your business grows, VoIP is a cost-effective and convenient way to equip your entire workforce in an efficient way.
