Identify phone lines, alarms, payment terminals and other services that may need attention before the analogue network is retired.
Moving away from analogue services is a planning exercise that reaches beyond the desk phone. A business may have older connections supporting equipment that is rarely touched, so an early inventory helps reveal dependencies before a migration is booked.
Start with the services you rely on
- Telephone numbers used by customers, suppliers and colleagues.
- Alarm, lift, entry and monitoring equipment connected to existing lines.
- Payment terminals, fax machines and other devices with separate suppliers.
Build a practical migration plan
Need help applying this advice?
Talk to the team about your current setup and the changes you are considering.
Ask the provider responsible for each service what will change and what replacement is suitable. A new phone system alone does not establish that an alarm or monitoring device is compatible. Include power requirements, emergency calling arrangements and the effect of an internet outage in the discussion.
- List the telephone numbers and services at each location.
- Ask each supplier to confirm the technology and compatibility.
- Agree suitable replacements and confirm number-transfer arrangements.
- Schedule installation, staff training and a controlled test.
- Retire old services only after the replacement has been accepted.
A clear inventory gives every supplier the same starting point.
Key information
- Check the current migration timetable with your provider.
- Confirm compatibility individually for specialist connected equipment.
- Keep a record of the agreed testing and handover arrangements.
