All IP switch off-readiness

The All IP clock is ticking. Your real deadline could be sooner. Legacy services are being withdrawn, but operational constraints and migration planning can bring your practical deadline forward. Find out how Wanstor can help with a seamless migration plan and implementation.

Find what still relies on old phone lines before the All IP switch-off

Many businesses have addressed their phone lines but overlooked other services that may still depend on legacy connections. Our assessment helps identify potential risks across:

  • Alarm systems
  • Lift emergency phones
  • Door entry systems
  • Monitoring equipment
  • Payment and EPOS terminals

Complete the form and we’ll review your requirements and advise on your next steps towards All-IP readiness.

What we’ll check


Interim connectivity options

We'll check if you'll need temporary internet solutions during the migration, so you aren't effected by downtime

Hidden dependency check

We'll full scope out your estate to see exactly what depends on legacy connections.

Multi-site support

Our migration solution is tailored to your sites, whether you have 1 or 50.

What is changing?

Analogue is on its way out. All IP is taking over.

And it’s not just your phones that need attention. Alarms, lifts, payments, door entry and monitoring systems could still depend on legacy lines. The challenge is finding those hidden connections before they become an operational problem.

That means the real question isn’t “Are our phones ready?” It’s “What else is still connected?”

PSTN, ISDN and related legacy services are being withdrawn on 31 January 2027

Your phones may be digital. Is everything else?

When legacy services are withdrawn, a few other things may become exposed or stop working altogether.

Alarm Signalling

Fire, intruder or monitoring systems may still rely on legacy connections.

Lift emergency phones

Emergency lift communications may need review before migration.

Payment terminals

EPOS or card-payment systems can cause trading disruption if overlooked.

Door entry

Access systems, intercoms or gates may still use older services.

Monitoring systems

Operational monitoring or alerting equipment may still be connected.

Other legacy equipment

Older devices can remain connected long after phones have moved.

Different organisations face different operational risks

The All IP deadline is the same for everyone. The risk isn’t. Your sites, systems and operational constraints determine when you really need to move. Complex estates, internal sign-offs and supplier lead times can all bring that deadline closer. Don’t plan to the switch-off date. Plan to the date your business needs to be ready.

For Professional Services

Your All IP deadline could arrive sooner than you think.

Multiple offices, internal approvals, supplier lead times and operational constraints can all bring your practical migration deadline forward. Planning early gives you time to uncover legacy dependencies and make the move without unnecessary disruption to day-to-day operations.

For Care Homes

Some connections are too important to discover the hard way.

Alarms, lift lines, access systems and emergency communications can all play a role in resident safety and continuity of care. Understanding which services still rely on analogue infrastructure helps you plan the move to All IP without putting critical services at unnecessary risk.

For Not-for-profits

The switch-off shouldn’t become an unplanned expense.

With limited IT resource and budgets already under pressure, discovering legacy dependencies late can create disruption you don’t need. Identifying what needs to change early gives you more control over your migration, your costs and continuity of service.

How Wanstor helps

Before you replace anything, find out what actually needs replacing.

Wanstor looks beyond the obvious phone lines to identify the legacy connections your business still depends on. We’ll help you assess the risk, prioritise what matters and plan your move to All IP without unnecessary disruption.

Here’s how we’ll work on it with you:

Confirm which dependencies create operational or migration risk. Define the right migration route, timescales and any interim requirements. Move to the right modern connectivity solution with support through transition.

 

Why Wanstor?

Your existing provider may know the connection. Wanstor brings the wider IT context, helping you uncover hidden analogue dependencies, assess the operational risk and plan your move to All IP across systems, sites and services.

And if time is tight, we can explore interim connectivity options to help keep operations moving while the permanent solution is delivered.

 

Wider IT context

Wanstor understands the wider IT environment, not just the individual line being replaced.

Hidden-dependency discovery

Support identifying overlooked systems before they become operational issues.

Interim connectivity options

Where a permanent solution needs more time, temporary connectivity may help reduce risk.

PSTN

Finding a hidden dependency now is inconvenient. Finding it after switch-off is worse.

Let Wanstor help you identify what’s still relying on legacy services and understand your next move before the deadline makes the decision for you.

Frequently Asked Questions

What systems could be affected by All IP Switch Off?

It’s not just your phones. Alarm and monitoring systems, lift emergency lines, payment terminals and door-entry systems may also rely on old analogue connections. If they haven’t been identified and moved to an appropriate replacement, they could be affected when legacy services are withdrawn.

We already use digital phones. Do we still need to check?

Yes. Digital phones don’t necessarily mean everything else is ready. Other services, sites or equipment may still rely on analogue connections, including alarms, lifts, payments and monitoring systems. That’s why it’s worth checking the wider business rather than assuming the phone migration has covered everything.

What happens after we submit the form?

A Wanstor specialist will review the details you provide and confirm the most relevant next step within a few hours. There’s no obligation, and the aim is to understand what you’re concerned about and whether further assessment or migration support is needed.

Can Wanstor help if we have left All IP migration late?

Yes. Leaving it late doesn’t mean you’ve run out of options. Wanstor can help identify what needs attention and accelerate the migration process. Where a permanent solution needs more time, interim options such as mobile or satellite connectivity can also be considered to help keep operations moving.

How long does All IP migration usually take?

There isn’t one migration timeline that fits every organisation. The work required depends on what still relies on legacy services and the complexity of your sites and infrastructure, which is why identifying dependencies early matters. However, we have rolled out migration services to customers within 2-4 weeks.

Can Wanstor support multi-site organisations?

Yes. Wanstor works across multi-site environments and can approach migration in stages rather than treating every location the same. Your requirements can be assessed site by site, helping identify dependencies and build a rollout around the needs of the wider estate. Wanstor documentation also shows experience conducting estate-wide discovery and site surveys and delivering phased, site-by-site network rollouts.

What happens to existing lines or providers?

You don’t necessarily need to change everything at once. The first step is understanding which existing services need to migrate, which can remain, and whether any contractual or notice-period requirements apply before changes are made.
