If you want a smooth transition, the goal is to avoid surprises. The best approach is an audit first, then a staged migration and testing plan.

Step-by-step checklist
- Inventory every line and device: list all phone numbers, extensions, analogue/ISDN lines, and any devices plugged into phone sockets (including “forgotten” lines at remote sites).
- Identify critical services: alarms, lift phones, emergency phones, payment lines, intercoms—anything safety- or revenue-critical.
- Check connectivity: confirm broadband/fibre quality at each site and whether you need a business-grade circuit, backup connectivity, or network upgrades.
- Decide your target setup: hosted/cloud VoIP, SIP trunks into an existing phone system, or a full unified communications platform.
- Plan for resilience: decide what happens during a power cut or broadband outage (battery backup for key equipment, call diversion rules, mobile fallbacks).
- Test compatibility: validate alarms, diallers, and any modem-based equipment early—before committing to dates.
- Migrate in phases: start with a pilot group, then roll out site by site or department by department.
- Train staff and update processes for reception/call handling, voicemail, transfers, remote working, and call recording policies.
- Cut over and monitor: track call quality, missed calls, and customer feedback; fix issues quickly.
FAQ
Will we have to change our phone numbers?
Usually, no. In most cases, you can keep existing numbers and transfer (port) them to your new provider or platform. The key is to plan the porting window and avoid leaving it to the last minute.
Will VoIP work in a power cut?
Not by default. If your premises lose power, your broadband router and VoIP devices may stop working. Businesses typically solve this with battery backup for key equipment, call forwarding to mobiles, or secondary connectivity—depending on how critical phone access is.
What about alarms, lifts, card machines, and fax?
These are the areas most likely to cause problems if you wait. Some devices can be replaced with IP-ready models, some move to mobile/cellular connectivity, and some may need specialist adapters or updated configurations. The safest approach is to identify and test each device early.
How long does a VoIP migration take?
It depends on the number of sites, lines, and connected devices. A small office can move in days or weeks. Multi-site organisations may need a phased programme over months—especially where alarms, legacy systems, or network upgrades are involved.
Call to action: start your VoIP plan this month
Even if your current phone system still works today, the direction of travel is clear: the UK’s traditional landline services are being withdrawn as the country moves to digital voice. Starting now gives you time to audit, test, choose the right supplier, and migrate with minimal disruption—rather than being forced into a last-minute change.
- Schedule an audit of lines and connected devices.
- Pick a migration date and work backwards with a phased rollout.
- Lock in a cost-effective solution that supports modern working.
