What Are the Drawbacks to VoIP for Businesses?

October 10, 2022

As the landline shutdown approaches in 2025 in the UK, there is a lot of attention being given to business VoIP phone systems. While many businesses have already made the switch to VoIP, there are still 98% of small businesses are undecided about whether or not to make the switch. The key benefits of VoIP for businesses are its scalability, flexibility, and cost savings. 

With VoIP, businesses can easily scale their phone system up or down as needed, without incurring any additional costs. VoIP is also much more flexible than traditional landline systems, allowing businesses to easily add or remove features as needed. 

Finally, VoIP can save businesses a significant amount of money on their monthly phone bills. When compared to traditional landline service, VoIP can be up to 75% cheaper. For these reasons, business VoIP is the best available technology for businesses of all sizes.

How does VoIP Work?

A business VoIP phone system functions by using the internet to route calls. This means that instead of using traditional telephone lines, VoIP systems use the internet to connect calls. In order to do this, VoIP systems compress the sound of a person's voice into digital data that can be transmitted over the internet. When the data reaches its destination, it is decompressed and played back as sound. This process happens very quickly, and most people cannot tell the difference between a call made using VoIP and a call made using a traditional phone line.

Disadvantages of VoIP for Businesses 

As a small business owner, you're always looking for ways to save money and improve your operations. If you're considering making the switch to VoIP, you should be aware of the following drawbacks. However, there are also solutions to each of these problems.

Relies on Good Internet Connection

A business VoIP phone uses the internet to transmit calls, so a fast and stable connection is needed for it to work to full capacity. If your business is in a rural area, call quality may not be the best and could lead to dropped or missed calls. In addition, VoIP requires more bandwidth than a traditional phone line, so your internet service provider may need to upgrade your business's internet package. 


In order to best take advantage of business VoIP, it is important to have a strong and reliable internet connection. A fibre internet connection is ideal for business VoIP phone service because it can provide the high-speed and low latency that is necessary for clear voice quality. 

A fibre internet connection can help to improve your business's overall productivity by providing a fast and reliable way to connect with customers and clients. If you are interested in business VoIP but are concerned about your internet connection, consider investing in a fibre internet connection for your small business. Doing so could prove to be a fruitful investment that helps your business stay connected and efficient.

Latency and Jitter 

One of the most common problems of a business VoIP phone system is latency, which is the delay between when you speak and when your words are heard on the other end. This can be caused by a number of factors, including internet congestion and problems with the VoIP system itself. 

Jitter is another common issue, which refers to fluctuations in latency. Jitter can be caused by a number of things, including network congestion and signal interference. 


  • Make sure your internet connection is as fast and reliable as possible. 
  • Configure your router correctly for VoIP traffic. 
  • Increase your bandwidth if possible
  • Using quality equipment and scheduling regular maintenance can help to keep jitter to a minimum.

Emergency call issues

With a traditional business phone system, emergency services can easily identify the location of the business and dispatch help. With VoIP, however, the actual location of the business may not be clear to emergency services. This is because VoIP uses the internet to route calls, which means that the call could be coming from anywhere. 


Businesses that rely on VoIP for their business phone needs should make sure to provide emergency services with their physical address so that they can be quickly located in the event of an emergency.
