Introduction
VoIP has been around for quite some time now, but it's only in recent years that it has become a popular communication solution for businesses. It has gained immense popularity as a communication solution for companies, and now, the technology has evolved. Businesses that have switched to VoIP are experiencing significant benefits of VoIP and the need to switch from ISDN to a cloud-based solution. From reduced costs to increased productivity and flexibility, VoIP is changing how businesses communicate.
So now you may be wondering how this technology could affect your business. Do you need to start thinking about using VoIP? Is it something you really need? Don't worry; we're here to help answer those questions for you. Keep reading to find out more.

What is VoIP?
If you're unfamiliar with VoIP, it's basically a technology that lets you make phone calls over the internet. It's like having a regular phone conversation, except instead of using a traditional phone line, the sound of your voice is turned into a digital signal that gets sent over the internet. This signal is then turned back into sound at the other end, so you can hear the other person's voice and have a conversation just like you would with a regular phone.
So why use VoIP instead of a traditional phone line and why is its popularity on the rise? One reason is that it can be cheaper since you don't need to pay for a separate phone line. Plus, it's very flexible because you can use it from anywhere with an internet connection, whether at home, in the office, or on the go. And because it's all digital, you can also use features such as video calling and instant messaging, which you might not have with a regular phone line.

Do I really need VoIP?
If your business relies heavily on communication, then the answer is yes. VoIP is rising in popularity as it offers many advantages over traditional phone lines, including reduced costs, increased flexibility, and improved productivity. VoIP can also be scaled up or down depending on your business needs, making it a cost-effective solution for businesses of all sizes.
We also shouldn't forget about the impending switch-off happening in 2025 with BT's "The Big Switch off", which we will explain later in this article.
5 business benefits of VoIP
Here we've highlighted some of the top business benefits of VoIP and explained why now is the time to get it in place in your organisation. VoIP can provide an efficient, streamlined communication solution that meets your needs, whether you are a small business owner or a large corporation.
- Easy setup: You only need a calling device, internet connection, and VoIP system to get started. It's a straightforward process and so long as you work with an experienced provider, any disruption will be minimal.
- Advanced features: VoIP offers more than just voice calls. You can also use features like video conferencing and instant messaging to collaborate with your team and clients.
- Mobility: You can use your mobile phone as an extension of your office phone, no matter where you are. This is especially useful for companies with employees who work remotely or for those who operate in multiple locations.
- Cost-effective: VoIP calls are cheaper than traditional landline services. The installation and maintenance costs are also lower, providing substantial savings for small to medium-sized business owners.
- Scalability: VoIP systems can accommodate unlimited lines, so you can quickly expand your communication capabilities.

Is it the end for ISDN and PSTN?
ISDN (Integrated Services Digital Network) is a traditional phone line technology that has been in use for many years by businesses. However, it is now being phased out in favour of VoIP. BT has decided to discontinue this outdated technology as it cannot keep up with modern advancements. ISDN and PSTN were first introduced over 30 years ago, in 1986. However, with the emergence of more cost-effective and more sophisticated alternatives, investing in improving the ISDN network no longer makes financial sense.
BT recognises that ISDN and PSTN are inflexible and not keeping pace with modern demands. Therefore, it is evident that IP technology is a more suitable choice to address future demands and facilitate business growth.

What does the big switch-off mean for your business?
If your business still uses ISDN, switching to VoIP is inevitable, which may seem daunting. However, it's important to remember that the switch-off is happening for a reason. VoIP offers many advantages over ISDN, including reduced costs, increased flexibility, and improved call quality. Making the switch to VoIP now will future-proof your business and ensure you stay caught up when the switch-off happens.
