Inventory Management: The Essential First Step of Any PSTN or POTS Migration

CIO Institute-Blog page

No one can deny today’s insatiable appetite for digital communications. When it comes to innovation, the sky’s the limit – but of course, success is constrained by your company’s existing communications systems. And the elephant in the communications room is more like a bull in the innovation China shop.  

Managing legacy phone systems including public switched telephone network (PSTN, also known as POTS) requires IT leaders to take the bull by the horns. 

  • In the U.K., copper-based PSTN services will be retired in December 2025. It might seem like there’s time before the official switch-off, but deadlines are hitting much sooner with providers announcing “Stop Sell” deadlines. 
  • Maintenance of PSTN systems add dead weight to IT budgets, creating a negative ripple effect across the organization. Up to 80% of technology leaders view technical debt as a hindrance to their company’s ability to innovate and the No. 1 cause of productivity loss, citing poor morale, customer churn, and lost deals.  
  • Enterprise digitalization has grown 162 times during the last 15 years. In sharp contrast, IT network capacity to handle this digital growth has only increased 43 times. As the modern communications alternatives, VoIP and unified communications as a service (UCaaS) applications require the right bandwidth and network resources to deliver exceptional user experiences.  

When the bull is bucking, how do you take control? It’s time to forge ahead with a proactive, holistic approach that fuels the modernization of all communications. 

Where Do You Start? By Tackling Your PSTN Inventory  

The next question naturally becomes how to enable this change effectively. This is a comprehensive undertaking, and a lot of companies struggle because they don’t have the human resources and IT professionals to do the leg work of migrating communications infrastructure. As a company that provides this expert support, Tangoe’s first step in guiding clients through their VoIP and UCaaS modernization program is clear: conduct an audit of your PSTN lines, building an accurate inventory. 

Why? Because you can’t know where you’re going until you know where you’ve been.  

You need to know what PSTN lines, assets, and services you have and, just as importantly, their related expenses. This is non-negotiable for any communications modernization project. Do the groundwork of cataloging resources in use and where their workloads reside and poof – you suddenly see:  

  • What you have,  
  • How it’s being used (or not used), and  
  • What you’re being charged for – so you can repurpose that spending into VoIP and UCaaS solutions. 

You get all the crucial information you need to plan for the future and put change in motion. 

But Wait – How are You Supposed to Do this Yourself? 

Inventory development and management is no cake walk. The amount of manual work required to find and document every legacy line, particularly without the right tools and automation, is exhausting. This is why so many companies have tapped out of that process – turning to Tangoe’s Advisory Services to update their inventory and clear the haze of their telecom expenses.  

Here are just a few of the main culprits our technology consultants assist with: 

Outdated information: Clients have trouble staying on top of their inventory as services change (which inevitably and irrevocably do in this rapidly moving space). All too often, these changes aren’t noticed until the billing stage, at which point details must be captured retroactively.  

Lack of standardization: It’s almost impossible to clean up your data with multiple disconnected systems, poor recordkeeping practices, and undisciplined processes.
