📞 Is your business ready for the PSTN & ISDN shutdown?
If your business is still relying on PSTN or ISDN multi line services, now is the time to start planning your migration.
⏰ Why act now?
From 1 October, BT is increasing prices for analogue services and ISDN by 40%, making it even more expensive to delay the move.
With around 52,000 legacy lines still in use, many businesses could soon face:
💷 Higher telecoms costs
⚠️ Increased operational risk
🔧 Outdated infrastructure
📉 Potential service disruption
And there is a bigger issue…
🚫 These legacy services will not continue indefinitely.
When the January 2027 shutdown arrives, affected services will be ceased.
That could impact much more than your business phone system.
🔹 Customer and supplier communications
🔹 Business critical phone systems
🔹 Security and alarm systems
🔹 Lift and emergency communications
🔹 Payment and connected services
🔹 Internal business operations
For many organisations, these lines have been operating quietly for years. The real challenge is discovering what depends on them before they are switched off.
🔍 What should your business do now?
A telecoms audit is a great place to start:
1️⃣ IDENTIFY
Find all PSTN and ISDN services still in use.
2️⃣ MAP
Understand which numbers, devices and systems depend on them.
3️⃣ ASSESS
Identify services that are critical to your operations.
4️⃣ PLAN
Choose the right replacement and migration strategy.
5️⃣ TEST & SWITCH
Allow enough time for installation, testing and a controlled transition.
⚠️ The worst time to discover that a critical business system depends on an old telephone line is after that line has been switched off.
📅 January 2027 may sound far away. It isn’t.
At Pen Telecom, we help businesses identify legacy services, understand potential risks and plan their transition to modern telecoms solutions with minimal disruption.
👉 Don’t wait until your lines are ceased to discover what depends on them.
