2025 has been a pivotal year for the UK’s transition to All-IP. We’ve seen a significant acceleration in the migration away from PSTN and ISDN services, driven by a combination of industry readiness, better communication from providers, and increased end-user awareness.
At Jola, we’ve helped hundreds of channel partners seamlessly migrate their customers to IP-based alternatives. Thanks to automation, APIs, and flexible provisioning, partners can now deliver voice and connectivity services that are not only more reliable and scalable but also easier to manage.
While the national migration figures look strong, there’s still a noticeable divide between large enterprises—who began planning early—and SMEs, who are only now starting to make the switch. That’s where the channel has played a crucial role, and Jola’s partners have been at the forefront of that movement.
Challenges
Early in the process, confusion over product equivalence and interoperability was a major barrier. Many organisations were unsure how to replace legacy life lines, alarm systems, and other critical monitoring equipment that depended on analogue lines.
Through 2025, these technical challenges have largely been addressed. The industry now offers mature connectivity solutions—like 4G and 5G LTE products—that can meet the reliability and resilience needs of these systems.
For Jola and our partners, automation has been key to overcoming the operational complexity of mass migration. Our SIM management portal (Mobile Manager), and provisioning APIs have simplified what was once a highly manual process. This has allowed resellers to migrate thousands of lines efficiently while maintaining customer confidence and minimising downtime.
Work to do
Although awareness is improving, the final stretch is always the hardest. Many small businesses and service providers still underestimate the urgency of migration—particularly those using legacy equipment such as life lines, fire and security alarms, and building management systems that rely on PSTN connectivity.
The challenge now is education: helping every business understand that the PSTN switch-off isn’t just about phone lines; it’s about ensuring that every device and service dependent on analogue connectivity is ready for the digital future.
Jola continues to invest in supporting partners with the right products and resources to manage that transition. Whether that’s through 4G/5G failover, VoIP-ready Fixed Wireless Access products, or specialist M2M SIMs for critical infrastructure, we’re making sure no customer gets left behind.
Government Support
Government awareness campaigns have improved in 2025, particularly through collaborations with Ofcom and the major network operators. However, the most effective communication has come from the channel.
Local resellers and MSPs—often supported by wholesale providers like Jola—are the ones engaging directly with the businesses still reliant on legacy lines. We’d like to see even greater clarity and coordination from central bodies to reduce mixed messaging, but overall, the visibility of the 2025 deadline has never been higher.
Innovation
All-IP isn’t just a replacement for legacy networks—it’s an enabler for innovation. Once every connection is digital, the possibilities for integration, automation, and AI-driven service delivery expand dramatically.
We’re already seeing partners bundle IP voice, mobile data, IoT, and unified communications into end-to-end solutions that deliver measurable value to customers. At Jola, we’re excited about the opportunities this creates for our channel. With a fully digital network, partners can deliver more intelligent, data-driven services, faster provisioning, and greater control than ever before.
The switch-off marks the end of an era—but more importantly, it’s the beginning of a smarter, more connected one.
