Cardiff is home to a strong mix of financial and professional services, media, and public sector-adjacent organisations, and like the rest of the UK, every business here is on the clock for the 2027 PSTN switch-off. Here's what business VoIP looks like specifically for Cardiff.
Why Cardiff businesses are switching to VoIP
As the Welsh capital, Cardiff has a dense base of financial and professional services firms, media organisations and public sector-adjacent bodies, all of which need dependable multi-line phone systems with proper call routing between departments.
Local relevance: the PSTN switch-off in Wales
Openreach is retiring the traditional analogue phone network by January 2027, exchange by exchange. Businesses around Cardiff still relying on ISDN or PSTN lines — including alarm systems, payment terminals and fax machines tied to the old network — need a migration plan before their local exchange stops-sell date. See Openreach's PSTN switch-off timeline for the current schedule.
