Cloud-based telephony services are rapidly becoming a necessity for charities as the UK telecommunications infrastructure is undergoing a key shift. With the national landline switch-off approaching in 2027, many organisations are beginning to rethink how their telephone systems support staff, volunteers and the communities they serve.
Traditional copper-based phone networks will be retired in favour of internet-based alternatives. For charities still using legacy landlines or on-site PBX hardware, this change means that older business phone systems will soon stop working altogether.
Charities already operate under distinctive pressures. Budgets are tight, teams often work remotely or in hybrid roles, and reliable communication with donors, beneficiaries and partners is essential. When phone systems fail or become outdated, the impact goes far beyond inconvenience. It can affect fundraising campaigns, safeguarding responsibilities and day-to-day customer service.
In this guide, we’ll explain what cloud-based telephony services are, why the upcoming switch-off matters, and how charities can move to a cloud-based phone system that is more flexible, scalable and cost effective. Most importantly, we’ll help you decide whether the transition is right for your organisation and how to approach it with certainty.
What Are Cloud-Based Telephony Services?
Traditional telephone systems rely on physical copper lines connected to the Public Switched Telephone Network (PSTN). In general, charities using fixed telephony also rely on on-site PBX hardware to route phone calls between desks and external numbers.
A cloud-based telephony system works very differently.
Instead of relying on copper lines and on-site infrastructure, cloud-based telephony services use an internet connection to transmit voice data. Calls are delivered via Voice over Internet Protocol (VoIP), which means staff can make and receive calls from almost any device connected to the internet.
In a hosted telephony model, the core phone infrastructure sits securely in the cloud rather than in a server room or office cabinet. The provider manages the platform, updates and reliability of the system.
The 2027 Landline Switch-Off: What Every Charity Needs to Know Now
Across the UK, telecommunications providers are phasing out the legacy PSTN and ISDN networks that have supported landlines for decades. The complete shutdown for all PSTN and ISDN services is now scheduled for the 31st of January 2027.
This transition is often referred to as the “landline switch-off”.
Once the switch-off happens, traditional copper-based phone services will no longer function. Any telephone systems relying on PSTN or ISDN lines will need to migrate to digital alternatives such as cloud-based telephony services.
For charities, the implications are substantial.
Many organisations still rely on older phone systems installed years ago. These systems often offer support to fundraising teams, helplines, safeguarding services and donor support. If they remain unchanged, those services could be disrupted when the old network infrastructure is retired.
Doing nothing carries several risks:
- Legacy telephony systems may stop working entirely
- Replacement hardware may become difficult to source or support
- Maintenance costs for ageing systems may increase
- Charities could struggle to support remote working teams
Waiting until the last minute increases the risk of delays, rushed installs, and service disruption. Starting early allows a smooth and well-planned transition. (Neel Mavji, Head of IT Communications).
The switch-off is an opportunity to undertake a digital transformation process and modernise communication systems, improve customer experience, and adopt tools that support flexible working environments.
The Key Benefits of Cloud Telephony Services for Charities
Switching to cloud-based telephony services isn’t just about keeping phone lines active after 2027. It can significantly improve how charities communicate internally and externally. A modern cloud-based phone system offers far more advanced features, which bring many advantages to charities:
1. Improved Donor & Service User Experience
Many traditional business phone systems offer limited functionality. Calls may be routed manually, voicemail systems may be basic, and tracking communication can be difficult.
With cloud telephony, charities can introduce:
- Intelligent call routing and analytics without additional hardware
- Automated menus
- Call recording to ensure important conversations are documented and handled efficiently.
- Better visibility of phone calls and call history, which also improves accountability and helps teams maintain high standards of customer service.
These tools help staff respond quickly to donor queries or service users who need assistance.
2. Scalability for Growth Campaigns
Fundraising campaigns often create unexpected spikes in call volume. Traditional systems can struggle to cope with this demand.
With cloud-based telephony services, capacity can expand quickly without installing new hardware. especially valuable during fundraising appeals, awareness campaigns or seasonal donation drives.
Your telephony system grows when demand increases and scales back when activity slows down. Additional users, numbers or features can be activated in minutes. That scalability helps charities stay agile while keeping costs under control.
3. Support for Hybrid and Outreach Teams
Charity teams infrequently work from a single location anymore. Staff might operate from the office, at home or within community outreach environments.
A cloud-based phone system supports this reality by allowing calls to be made and received from almost any internet-connected device. Systems can be managed remotely through simple online dashboards.
Charity staff working remotely can still make and receive calls from desk phone devices, laptops or mobile devices and can integrate phone systems with tools like Microsoft Teams and other unified communications platforms to streamline communication.
4. Better Protection Against System Disruptions
Older phone systems can become single points of failure. If a local server or PBX system stops working, the entire organisation may lose access to incoming calls.
A cloud-based telephony system is hosted across resilient infrastructure. Calls can be redirected easily, and services remain accessible even if an office location experiences trouble.
This resilience also supports broader IT planning. Our article on preventing system outages explains why modern infrastructure is essential for charities that depend on continuous communication.
In short, cloud-based telephony services convert a traditional phone network into a flexible digital communication platform. For charities working across offices, community locations and remote environments, that flexibility can make a significant difference.
5. Cost Efficiency and Reduced Infrastructure
Traditional phone systems regularly require expensive hardware upgrades, maintenance contracts and on-site support. Hosted telephony removes much of that burden. Infrastructure is managed in the cloud, updates happen automatically, and organisations predictably pay predictable monthly costs. For charities managing limited budgets, this shift can make communication technology much more cost effective.
As Neel Mavji, the Head of IT Communications at Qlic IT said in our webinar How to Cut Costs & Prepare for the 2027 PSTN Switch-Off, What many organisations don’t realise is that legacy services often impact bills long after they are no longer being used.
Watch the full webinar to learn more about the transition from traditional telephone systems to modern cloud-based solutions ahead of the 2027 PSTN switch-off. Understand how organisations, particularly charities, often overpay for legacy services, unused lines, and hidden contract renewals due to confusing billing, and how by moving to VoIP technology, they can achieve greater operational flexibility.
Is Your Charity Ready to Move from Fixed to Cloud Telephony?
If you’re hesitant about whether your organisation should begin the transition, a quick review of your current setup can help.
Ask the following questions:
- Are you still using PSTN or ISDN lines for your phone systems?
- Do staff need to support remote working or hybrid roles?
- Is it difficult to track or analyse incoming phone calls?
- Does your current telephony system struggle during fundraising campaigns?
- Are you planning ahead for the 2027 landline switch-off?
- Can your existing system integrate with tools like Microsoft Teams?
- Is your current solution scalable if your charity grows?
If several of these questions underline gaps, it may be time to explore cloud-based telephony services.
