PSTN Replacement Toolkit

In January 2027 the UK copper PSTN and ISDN network is being retired and all traditional phone lines and the different services that run over these analogue phone lines need to be upgraded to an IP-based solution. Jola has developed a PSTN and ISDN Replacement Toolkit with multiple solutions for different customer requirements.

Our PSTN and ISDN Replacement Toolkit contains:

  • SIP Overlay service - designed for PSTN replacement (with unlimited option)
  • Fully managed hardware including cellular, SIP voice gateway, ATAs and ISDN convertors
  • Options for porting existing numbers
  • Numbers available across the UK
  • Market-leading, fully automated, white-label provisioning portal
  • CloudNumber – allows users to connect to our PSTN replacement services via their mobile phone

A variety of Jola hardware, including Robustel, Teltonika and TP-Link routers plus Grandstream ATAs and ISDN-TAs can be ordered on an OpEx ‘Device as a Service’ (DaaS) model.

PSTN Replacement Toolkit Frequently Asked Questions

How can partners deliver PSTN replacement services?

Jola enables partners to deliver PSTN replacement services through a fully channel-focused model.

Partners can use Jola’s Mobile Manager platform, connectivity portfolio, and hardware options to design and deploy tailored solutions for their customers. With access to white-label services, flexible commercial models, and UK-based support, resellers can create new recurring revenue streams while helping customers transition to modern, IP-based communications.

Jola also provides guidance, provisioning support, and scalable solutions to help partners manage both simple migrations and large, multi-site rollouts.

What happens if you don’t switch before the PSTN switch-off?

If services are not migrated before the switch-off, PSTN and ISDN lines will simply stop working. This could lead to loss of phone service, disruption to critical systems (such as alarms or payment devices), and potential compliance or safety risks.

Planning early ensures a smooth transition and avoids last-minute disruption. Jola’s solutions are designed to help partners proactively migrate customers with minimal downtime.

What businesses need a PSTN replacement solution?

Any business currently using analogue phone lines, ISDN, or PSTN-dependent devices will need to migrate. This includes:

  • Offices using traditional phone systems
  • Alarm systems, lift lines, and payment terminals
  • CCTV and remote monitoring solutions
  • Healthcare, retail, and hospitality environments
  • Multi-site or remote operations

Jola specialises in helping partners deliver solutions for both standard voice replacement and more complex M2M/IoT use cases.

What is Device as a Service (DaaS) in PSTN replacement?

Device as a Service (DaaS) is a flexible model where hardware is provided as part of a monthly subscription, rather than an upfront purchase.

DaaS enables businesses to deploy modern connectivity solutions without large capital expenditure. Jola’s DaaS offering bundles hardware and connectivity into a single, predictable monthly cost, making it easier to scale and manage deployments.

What services are included in Jola’s PSTN replacement toolkit?

Jola’s PSTN replacement toolkit includes a wide range of services, such as:

  • Hosted VoIP and SIP solutions
  • Mobile data & Voice SIMs (including 4G/5G broadband)
  • IoT and M2M connectivity for legacy line replacements (e.g. alarms, lifts, CCTV)
  • 4G/5G routers and hardware
  • Fixed IP, Private APN, and L2TP connectivity options
  • Access to Mobile Manager for full SIM and service control
  • Optional Device as a Service (DaaS) for bundled hardware and connectivity

This allows partners to build tailored solutions for everything from voice services to critical infrastructure connectivity.

What is a PSTN replacement toolkit?

The PSTN replacement toolkit is a comprehensive set of products, services, and resources designed to help businesses transition away from analogue lines quickly and efficiently.

Jola’s toolkit brings together connectivity, voice solutions, hardware, and management tools into a single, partner-friendly offering. It enables resellers to assess customer needs, recommend suitable alternatives, and deploy replacement services at scale.

What is PSTN replacement and why is it happening?

PSTN (Public Switched Telephone Network) replacement refers to the UK-wide switch-off of traditional analogue phone lines, which is scheduled to be completed by 2027.

The legacy copper network is being retired in favour of IP-based (internet protocol) services, such as VoIP (Voice over IP), hosted telephony, and mobile/data connectivity. These modern solutions offer greater flexibility, scalability, and cost efficiency, while supporting the growing demand for digital services and cloud-based communications.
