Portsmouth is home to a strong mix of maritime and marine services, professional services, and retail, 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 Portsmouth.
Why Portsmouth businesses are switching to VoIP
Portsmouth's naval and maritime heritage sits alongside a growing base of tech and professional services firms, both of which need phone systems that scale with multi-site or multi-department operations.
Local relevance: the PSTN switch-off in Hampshire
Openreach is retiring the traditional analogue phone network by January 2027, exchange by exchange. Businesses around Portsmouth 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.
