Think you've moved beyond PSTN? You might want to check again.

The UK's copper network is being retired in January 2027. While many organisations have moved their phones to the cloud, hidden dependencies often remain across buildings, sites and critical infrastructure.

We're ready to help uncover every PSTN-dependent service in your organisation, assess the risk and manage your migration from discovery through to delivery.

Know what's affected. Fix it before it becomes a problem.

HOW INTERCITY HELPS

1. DISCOVER HIDDEN DEPENDENCIES

We assess your estate to identify every service still relying on PSTN, ISDN or copper-based connectivity.

From a single office to a multi-site operation, we help uncover the risks that are often missed during digital transformation programmes.

2. BUILD YOUR MIGRATION PLAN

Our specialists design a tailored migration strategy based on your sites, services, compliance requirements and operational needs.

That could include: Full fibre connectivity, Ethernet services, Business broadband, Cloud communications, Cellular connectivity & Backup and resilience solutions.

We're focused on finding the right outcome, not forcing a one-size-fits-all migration

4. MANAGE DELIVERY END-TO-END

Replacing a line is easy.

Managing multiple suppliers, technologies, locations and stakeholders isn't.

Intercity manages the entire journey, helping minimise disruption and keeping your migration programme on track from assessment through to implementation.

5. OPTIMISE YOUR ESTATE

The PSTN switch-off creates an opportunity to improve more than connectivity.

Many customers use the programme to modernise: Business communications, Network resilience, Internet connectivity, Backup connectivity. Site performance & User experience.

So the outcome isn't simply replacing copper. It's creating a more resilient and future-ready organisation.
