Looking to prepare for the 2025 switch off, enhance the way you do business and improve your communication strategy? Well, moving to a VoIP solution has the power to do just that.

The Openreach ISDN switch off announcement in 2015 signalled that they would stop taking new ISDN orders in 2020, with a view to switching-off and deactivating its ISDN network completely in 2025.

The bottom line is that you need to start planning for the ISDN switch off soon to ensure you’re making the best decisions for your company. At Lily, we’re offering expert advice on how to prepare for the switch off and how to introduce VoIP systems to your organisation.


In simple terms, VoIP phone systems convert voice into digital data and send it over an internet connection. With additional features like CRM integration, unified comms, hot desking, analytics and monitoring, VoIP solutions provide multiple opportunities to improve your organisational communication strategy.

With all the traditional features of telephone systems including caller ID, voicemail and call forwarding, transitioning to a VoIP phone system can be simple and straightforward.

What are the benefits of VoIP?

Cost Effective

Hosted phone systems take advantage of VoIP technology which can deliver high-quality calls, whilst also saving between 30% to 60% on your monthly line rental when switching from on-premises solutions using older ISDN or Analogue lines – helping you save money and enable a seamless user experience.


For businesses looking to expand, VoIP is an ideal solution for effective communication. You won’t have to purchase additional hardware or extensions to scale your operations since your phone network is digital – giving you the bandwidth you need to accommodate peak season surges.

Lily Cloud is designed to scale, so it suits all sizes of business, whether you have a single home office or multiple locations around the globe. With on-demand features and same-day provisioning, you can add or remove users quickly and easily. 


If you need a business communication system that is as mobile as you are – VoIP is for you. Whether you work in an office, at home or on the road, you can have a faultless experience anywhere with a broadband connection.

In our current age of hybrid working, this level of accessibility is especially helpful if you’re managing a mobile workforce; giving you the ability to keep in touch with your team regardless of their location.

Hosted VoIP Phone Systems

The business phone landscape has changed forever and continues to change in light of the 2025 ISDN switch off. One of the best and preferred alternatives to ISDN is Hosted VoIP, offering a multitude of benefits which advance ISDN.

Lily Cloud is our fully hosted VoIP phone system, bringing you all the features that you know and love from an on-premises phone system, delivered through the cloud.

Switching to a cloud delivered service means that you not only get a range of great features on your handset, but you also have access to these features on a web portal and mobile application – meaning you can access your communications on the go.
