Why is VoIP not as reliable as a phone call using a landline?

VoIP technology allows you to make phone calls using an internet service. Because VoIP uses the internet, those using a VoIP phone service do not need to rely on a landline phone to make calls.

VoIP has many advantages over a traditional landline phone system, so when choosing a phone service for a business, it’s no surprise many decide to invest in VoIP telephone services.

However, the fact that VoIP relies on internet service means there can be issues if there’s a power outage or there’s a problem with the internet service provider. In comparison, a landline phone service uses the telephone network, which tends to be more reliable.

To understand whether VoIP or traditional landline is better for your home or business, we need to understand the pros and cons. Keep reading to find out what these are so you can choose the right new phone system.

What is the difference between VoIP Vs landline phones?

Suppose you’re thinking about upgrading your business phone system. In that case, you may be debating whether to go for a traditional phone system, as in a landline phone system, or you’re considering more modern VoIP solutions.

The main difference between VoIP and landline is that cloud-based VoIP uses your internet connection to place and receive calls, while a landline uses the copper wire phone network.

How Landline Phones Work

Landline phones are the traditional type of phone used for many years. They use a copper wire to connect to the phone network, whereas a mobile phone uses wireless technology, and a VoIP uses the internet to connect to the VoIP network.

Landline telephones are still widely used to make voice calls, but many people are switching to VoIP (Voice over Internet Protocol) service because of the additional benefits and features.

Pros and cons of landline systems


  • Reliability – a traditional landline phone is reliable. Although phone lines can be affected by bad weather, on the whole, their wire connections offer a reliable service.
  • Good call quality – poor internet connection can affect VoIP’s audio quality, which you don’t have to worry about with a landline.


  • Higher costs – phone companies will charge more for landline services, especially if you want additional features like voicemail. It can also cost more to call internationally, so costs can add up if your business is international.
  • Technology – traditional phone systems are a dying breed. Phone companies aim to switch off copper systems by the end of 2025. Also, businesses often need to make calls from anywhere, which you can’t do with an analogue phone. So it can be very restricting for a business.

What is a VoIP Phone System?

A VoIP phone system is a service that uses an internet connection to make phone calls. VoIP systems offer the flexibility of making calls from anywhere worldwide by transmitting your voice as digital packets over the internet.

Pros and cons of VoIP systems


  • Low cost – a VoIP system uses your Internet connection to place and receive calls rather than a traditional phone line. Most VoIP providers will charge per second and don’t charge a call setup fee. Rates will change based on the type of call and calling overseas, but the per-second rates and no setup makes VoIP considerably cheaper.
  • Cost-saving solutions – VoIP phones allow you to make international calls and add multiple phone lines at a much more budget-friendly cost than landlines.
  • A variety of features – VoIP allows you to add additional services such as a Virtual Assistant, automatic call forwarding, voicemail to email, and more. It also allows you to receive calls to your cell phone, so you don’t ever have to worry about missing an important call.
  • Better functionality – you can do much more with VoIP than voice calls, such as video calls and multimedia messages.


  • Need for reliable Internet – there is the risk of disruption to your service and the potential for dropped calls. However, the evolution of technology is quickly making this less and less of an issue. 

Why is VoIP cheaper than using a telephone?

VoIP is cheaper than using a telephone for several reasons. First, VoIP uses your existing broadband internet connection instead of a phone line. You don’t have to pay for a separate phone line or business phone service.

Second, VoIP systems are often much cheaper to maintain than traditional telephone systems. Finally, VoIP offers many features and benefits that landlines cannot match, such as call forwarding, caller ID, voicemail, and more.

For these reasons, many businesses are choosing to switch to VoIP.

Is VOIP Service or Landline Service more secure?

Regarding security, both VoIP and landline services have pros and cons. Landlines are physically connected to your home or office, so they’re less likely to be hacked than an internet connection.

However, VoIP service uses encryption, so your conversations are more secure. If you’re worried about security, invest in a VoIP phone service.

Why would a business want to use VoIP?

For many reasons, as discussed above, a VoIP phone system is more reliable than a traditional landline. In addition, VoIP can be a more cost-effective solution for businesses, as you can avoid paying for expensive telephone lines and equipment.

Additionally, VoIP can be used with mobile devices, so employees can stay connected even when they are away from the office, making it easier to do business anywhere in the world.

VoIP makes growing your business easy, as you can add additional VoIP lines as your team grows. You can also set up numbers for specific marketing campaigns to track results.

How to choose a reliable VoIP provider

When choosing a VoIP provider, it is essential to consider the service’s quality and the company’s reliability. There are many VoIP service providers to choose from, so it is vital to research to find one that is reputable and has a good track record.

It is also important to ensure that the VoIP provider offers a good selection of features, such as call waiting, voicemail, and caller ID.
