Why Organisations Must Migrate to VoIP to Survive the PSTN & ISDN Switch Off

As BT further moves towards switching off PSTN and ISDN in 2025, Damian Hanson argues that businesses must migrate to VoIP now in under to future proof their organisations.

The new digital era is already well underway, and businesses of all sizes will need to adopt new technology to survive and thrive ahead of their competition. A key catalyst of technological advancement in telecommunications right now is BT’s announcement to switch off The Public Switched Telephone Network (PSTN) and the Integrated Services Digital Network (ISDN) in 2025.

These long-used, traditional phone networks are about to become a thing of the past. The switch off symbolises the biggest change in the telecoms industry in the last 30 years and will have ripple effects felt by businesses across industries.

There has never been a more crucial time to review your current telephony setup and understand exactly what the switch-off means for your business, and how shifting to internet-based, digital services could enhance your day-to-day operations.

The Switch Off: Failing to Prepare Is Preparing to Fail

The switch off deadline still feels far away. However, failing to prepare is preparing to fail. Quite simply, those currently using PSTN or ISDN must evolve or risk becoming extinct, unable to keep pace with their digital-savvy competitors. By 2025, those that do not migrate to a digital telephone system will have no working telecoms to utilise.

However, this does not mean the decision should be hurried. Careful consideration of a future communications provider, particularly for rapidly scaling businesses, is required to avoid your telephone system becoming a problem again further down the line.

At this critical time, decision-makers must see their preferred telecoms as an investment in the future of their business. Considering the options sooner rather than later is ideal, and while there is still enough time, this could make the difference between adopting a future-proofed telephony system, and one that needs replacing in 5 years due to further technological advancements.

When choosing a replacement telephone system, it should be an upgrade on the current system such as a cloud-based voice over internet protocol (VoIP) product that can stand the test of time and offer greater flexibility than wired telephony. It should also easily integrate with other key business systems and software. Siloed telecoms will only create efficiency issues further down the line.

There has never been a more crucial time to review your current telephony setup and understand exactly what the switch-off means for your business, and how shifting to internet-based, digital services could enhance your day-to-day operations.

Embracing the Benefits of Using VoIP Technology

Adopting a VoIP system continues to be an upward trend among businesses for a number of reasons. VoIP allows businesses to make and receive calls through its existing internet, rather than the PSTN or an ISDN network. This service will help businesses overcome the upcoming PSTN/ISDN obsolescence and will open avenues for additional benefits that were not previously accessible.

Cost efficiency aside, VoIP phone systems are favoured for the flexibility they offer. Cloud-based VoIP services allow you to make calls from anywhere and include additional features to integrate key Software-as-a-Service (SaaS) business tools with your telephony system. With remote working in mind, VoIP is a key enabler of the “work from anywhere” model that is becoming dominant across industries.

Being able to work from anywhere, at any time without seeing a negative impact on productivity or efficiency is now increasingly expected of all business systems – business communication tools are perhaps leading the way here.

Cloud-based services also depend on the fastest speeds the internet can provide and as we move into a world of 5G, which we know is 20 times faster than 4G, there are no doubts that it will enhance VoIP for businesses and become the new global standard utilised by all.

Implementing Future-Proof Communication Tools

To prepare for the switch off, business leaders first need to understand what telephony solutions are on offer to replace PSTN and ISDN. Ensuring the right technology is adopted that not only meets your current business needs but also needs that may arise in the future, is the most important consideration for businesses surrounding the switch off.

I would urge all businesses and organisations of all sizes to invest time, effort, and research into the telecom alternatives to ensure you get what you need from this service. If you still feel a bit lost in the jargon or are unsure about the process, then definitely seek expert help.

Ask for recommendations from others in your industry or check the internet for advice. Do this before you sign the dotted line to make sure you aren’t having to revisit your telecoms decision again too soon. CircleLoop will always be on hand to offer friendly, jargon-free support to those looking to make the switch, before the big switch off.
