A Beginner’s Guide To VoIP: How Does It Work?

VoIP, or Voice over Internet Protocol, allows users to make and receive calls over the internet. With traditional landlines being switched off by 2025, many UK businesses and households have started to think about how their communications will be affected and what they can do to prepare.

Making the switch to VoIP can be a simple process provided you follow the instructions set out by your provider and have the right equipment.


What Is VoIP?

VoIP is a communication technology that allows messages to be transmitted over the internet, unlike landlines which rely on copper wires to send and receive data. Due to VoIP’s reliance on the internet, users are able to make calls from anywhere in the world, establishing the technology as a top choice for global connectivity. 

Plus, users can take advantage of a more cost-effective communication package whilst enhancing their call quality with VoIP systems.

Lauren Davies of VoIP company bOnline comments: “It is always worth getting a little more clued up when it comes to VoIP as it is fast becoming a bigger and bigger part of all of our lives. With digital connectivity only increasing, this couldn’t be more important.”

How Does VoIP Work?

The modern technology works by converting your voice into digital packets of data and transmitting them over the internet to the receiver where the process is then reversed to reveal the voice message. When users speak into a VoIP-enabled device, the voice is first transformed into digital data using specialised algorithms known as codecs.

These packets are then divided into small segments and labelled with the sender and recipient IP addresses. They travel separately across the internet, making their way through routers and switches to ultimately reach the recipient.

Upon arrival, the data packets are reassembled in the correct order and converted back into audible sounds using the same codecs. This process ensures communication remains clear and efficient.

Why Are Landlines Being Phased Out?

UK landlines are gradually being phased out in order to prepare for the switch-off taking place in 2025. Traditional landlines have slowly become less adaptable to the mobile and remote work trends that now dominate society, prompting many telecommunication providers to shift their focus towards a digital solution.

Landline systems can also be limited in their functionality compared to modern alternatives, meaning there is a sense of demand for a more appropriate solution. VoIP is not only more affordable than landlines, but it is also rich in features and flexible, making it the natural replacement for landlines in the UK.


Will Other Devices Be Impacted?

It is worth noting that the transition to VoIP will potentially impact other devices and services. traditional devices such as older fax machines and security alarm systems that rely solely on analogue phone lines may require adaptations in order to work with VoIP.

Plus, emergency services will be closely tied to landlines, so it is essential to check how your UK VoIP provider will handle emergency calls and ensure your communications are not compromised. If you are unsure whether a device will be impacted by the 2025 landline switch-off, it is worth checking with your manufacturer and make any necessary adjustments sooner rather than later.


How To Make The Switch To VoIP In The UK?

Transitioning to VoIP can be a fairly easy process for both businesses and individuals alike. You will first need to find a reputable VoIP provider in the UK and compare their packages to find one that best suits your communication needs.

It is also worth checking your existing internet connection to ensure you have sufficient bandwidth to support voice and video calls without interruption.

Once you have chosen a VoIP product or package, you will need to download your VoIP provider’s application and follow the setup instructions. If you wish to keep an existing phone number, this may be possible by inquiring with your VoIP provider about number porting options.

Users should test their service will a few calls to get familiar with features and call quality before embracing the modernisation that VoIP can bring.
