As of 21 April 2026, schools, colleges, and multi-academy trusts are now moving into what is, for many, the last practical low-disruption window to replace legacy phone systems before the final phase of the UK’s PSTN retirement on 31 January 2027. If older analogue or ISDN-style services are still supporting your sites, now is the time to plan the move to VoIP and modern cloud telephony.
For education, this is not just about replacing handsets. It is about making sure your organisation has enough time for the full process: initial onboarding, discovery meetings, software demos, free trial access where suitable, number planning, and installation of your automated switchboard before pupils return for the new academic year.
