For many organisations, operational uncertainty and a lack of stakeholder alignment are stalling momentum. We see countless estates where PSTN lines remain hidden in plain sight, tied to critical services, yet are undocumented and unowned. This is where planning fails, and risk quietly grows.
Missed PSTN dependencies don’t just threaten service outages; they can derail cloud adoption, delay security upgrades, and introduce significant hidden costs. It’s a legacy issue with very modern consequences.
Top 5 Reasons Businesses Are Delaying Action
While most organisations have their eyes set on digital transformation, many still rely on a legacy network they’ve stopped tracking. The PSTN isn’t just a telecoms issue—it’s a structural risk that sits beneath your entire digital estate.
Here are the top five barriers we see preventing organisations from starting their migration.
Budgetary Constraints
Strategic budgets are always under pressure. Funds get tied up in current projects or are pushed into the next financial year. Without a clear scope and a solid business case, a PSTN migration project can struggle to justify its costs, especially when the ROI isn’t immediately obvious. Proactive planning is the key to building that business case and securing the necessary investment before it becomes an emergency.
Lack of Executive Ownership
When no single stakeholder champions the switch-off, the project stalls. Responsibility becomes fragmented between IT, facilities, and finance, leading to diluted accountability and a lack of control. In our experience, clear executive ownership is the single most important factor in accelerating planning and ensuring buy-in from all necessary departments.
Fear of Operational Disruption
The fear of disrupting critical services—from care alarms and lifts to payment terminals and security systems—can be paralyzing. This creates uncertainty and second-guessing about having the right replacement services or backup options in place. The irony is that the greatest risk of disruption comes from inaction, not from a carefully planned and managed migration.
Complexity and Unknown Dependencies
Inherited legacy systems, poor documentation, and hidden services often take IT and estates leaders by surprise. Unearthing a critical system tied to an old copper line raises difficult questions:
- What is this linked to?
- How deeply embedded is it?
Simply switching it off is a risk no one can afford to take. Our process begins by working with your internal teams to map these end-to-end dependencies, ensuring there are no surprises.
The “It’s Not Urgent Yet” Mindset
With a January 2027 deadline, it can be tempting to push the project back. However, leaving migration to the last minute creates a perfect storm of problems: engineer shortages, limited equipment availability, rushed implementations, and premium pricing from vendors.
The “cost of doing nothing” is a guarantee of higher expenses and greater risk down the line.
What Should You Do First?
The key is to move from awareness to action. A comprehensive audit is the only way to understand your true exposure.
We’ve put together a quick audit checklist to give you a structured starting point for your project. This checklist walks you through discovery, strategic readiness, and a review of your technology infrastructure and its operational impact.
