What type of phone lines do you currently use?
Select the option that best describes your current setup. Not sure? Choose “Not sure” — we can work it out.
Analogue phone lines (PSTN)
Standard BT lines, plugged into the wall. Most common in small offices.
ISDN lines (ISDN2 or ISDN30)
Digital BT lines, often used with a phone system. Higher capacity.
Already on VoIP or hosted
SIP trunks, Horizon, Teams Phone, or another internet-based system.
Not sure
You pay a BT or telecoms bill but aren’t certain what type of line it is.
How many phone extensions or handsets do you have?
Include all handsets, desk phones, and softphones across all your sites.
1–4 extensions
Sole trader or micro-business
5–19 extensions
Small business
20–49 extensions
Medium business
50+ extensions
Larger organisation
Do any of these use your phone line?
Select all that apply. These are “hidden” devices that are easy to overlook — and will stop working on 31 Jan 2027 if not migrated.
Intruder or fire alarm
Many alarm systems use a PSTN line to call the monitoring centre
Lift or elevator
Lifts legally require a phone line for emergency calls
Fax machine
Fax cannot be migrated to VoIP — must move to email-based fax or be retired
PDQ / card payment terminal
Older card machines may use a phone line rather than broadband or mobile
CCTV or door entry system
Some systems dial out over PSTN for alerts or remote access
None of the above
Only standard telephone handsets
What broadband connection do you have?
Your broadband type affects your migration options — full fibre is the easiest path.
Standard ADSL or copper
Older broadband over a copper phone line. Often slower than 20Mbps.
Fibre to the Cabinet (FTTC)
Fibre to the street, then copper to your building. Typically 40–80Mbps.
Full Fibre (FTTP)
Fibre optic cable goes all the way to your building. Usually 100Mbps+.
Leased line or Ethernet
Dedicated business connection with guaranteed speeds.
When does your current phone or broadband contract end?
This affects your migration timeline. Being in contract doesn’t stop you migrating — but it’s worth knowing.
Rolling / no fixed term
You can switch at any time without penalty.
Ends within 12 months
Good time to plan your migration ahead of renewal.
More than 12 months to run
Early exit fees may apply, but you still need to migrate before Jan 2027.
