Our cloud phone system is built for the modern, mobile-first business. Unlike traditional setups, this cloud phone system integrates directly with tools like Pipedrive and Microsoft Teams, allowing your team to stay connected anywhere in the world. Experience a cloud phone system that offers more than just calls—it offers business intelligence.
A Cloud Phone System, or UCaaS (Unified Communications as a Service), is a cloud-native platform that unifies business communication tools—including voice, video, messaging, and collaboration—into a single digital interface. Replacing traditional on-premise PBX hardware, it enables UK businesses to communicate via the internet using any device, ensuring continuity ahead of the 2027 PSTN switch-off.
What Is a Cloud Phone System and Why the UK Is Switching Now
Why UCaaS is the New Benchmark
The term UCaaS distinguishes this solution from simple VoIP. While all Cloud Phone Systems use VoIP (Voice over IP) as the underlying voice technology, UCaaS adds the essential unified platform layer:
| Component | Function | Advantage over Legacy PBX |
|---|---|---|
| VoIP | The core technology transmitting voice data digitally. | Eliminates expensive PSTN/ISDN line rental fees. |
| Hosted PBX | The cloud-based software replacing the physical server. | Eliminates upfront hardware CAPEX and ongoing maintenance. |
| UCaaS Platform | The single application unifying Voice, Video, Chat, and Apps. | Enables seamless hybrid work and boosts team productivity. |
UCaaS vs. Legacy PBX
| Feature / Capability | Traditional PBX (Legacy) | Basic VoIP (App Only) | Stride Cloud (UCaaS) |
|---|---|---|---|
| Infrastructure | Physical On-Site Server | Cloud-Based Dialer | Geo-Redundant UK Data Centres |
| Device Flexibility | Desk Phones Only | Mobile/Laptop Only | Unified: Desk, Mobile & Desktop |
| Collaboration Tools | None (Voice Only) | Basic Chat | Video, Chat, Presence & Teams |
| 2027 PSTN Ready? | ❌ Requires Replacement | ✅ Yes | ✅ 100% Future-Proof |
| Setup Cost (CAPEX) | £2,000 - £10,000+ | Low | £0.00 (Managed Setup) |
Strategic Comparison: Finding the Right System for 2027
The Critical Urgency: The 2027 PSTN Switch-Off
The move to the cloud is no longer optional for UK organizations. Openreach is retiring all copper-based landlines (ISDN/PSTN), forcing businesses to migrate to digital, IP-based solutions. A cloud based phone system for small business and enterprise alike is the only way to ensure your dial tone remains active after 2027.
Beyond compliance, the cloud meets the Hybrid Work Demand. Post-2020, employees require flexible tools that work from the office, home, or the road. By adopting a voip cloud phone system, you future-proof your business with AI features, real-time analytics, and total mobility.
The Cloud Advantage: Why Cloud Is the Best Choice for UK Businesses
The decision to choose a cloud based phone system is a strategic move that directly impacts your finances, operational resilience, and staff performance.
Maximum Flexibility
Unlike fixed, hardware-based systems, a cloud platform is inherently mobile.
- Work From Anywhere (WFA): Staff can make and receive calls, check voicemail, and manage their status using their professional extension number through a softphone (desktop application) or a mobile app.
- Device Independence: Use professional VoIP desk phones in the office or switch to a laptop when working remotely, maintaining one unified business identity.
- Business Continuity: In the event of an office power outage or severe weather, your entire communications system instantly fails over to mobile apps, ensuring you never miss a client call.
Cost Control
Cloud solutions fundamentally change your budgeting structure.
- Zero Upfront Capital Expenditure (CAPEX) : Avoid the high initial cost of purchasing and installing a physical PBX server.
- Predictable Operational Expenditure (OPEX): Pay a simple, fixed per-user, per-month subscription that includes maintenance and updates.
- Instant Scalability: Need to hire five temporary staff for a seasonal surge? Add five licenses instantly via the online portal. You only pay for what you use.
Superior Reliability
Stride’s cloud pbx phone system provides enterprise-grade reliability.
- Redundancy : Our platform operates from multiple, geographically separated UK data centres. If one centre has an issue, traffic is instantly rerouted, guaranteeing 99.999% uptime.
- Automatic Updates: Security patches and feature enhancements are managed by Stride, ensuring your system is always secure with zero disruption.
- 99.999% Uptime SLA: Enterprise-grade reliability guarantees your business stays connected.

The Unified Powerhouse: Core Features of the Best Cloud Phone Systems
A true UCaaS Cloud Phone System combines tools that enhance collaboration, customer service, and business intelligence.
Unified Communications for Team Collaboration
This is the key differentiating factor from basic VoIP. The platform unifies every communication method:
- Integrated Team Messaging: Built-in chat for instant messaging, group channels, and secure file sharing.
- HD Video Conferencing: Full video meeting capabilities with screen sharing and virtual waiting rooms.
- Real-Time Presence: See if a colleague is "On a Call," "Available," or "In a Meeting" across all devices.
Advanced Professional Call Management
- Auto-Attendant (IVR): The automated "virtual receptionist" that directs callers ("Press 1 for Sales").
- Intelligent Call Queues: Manage high call volumes efficiently with estimated wait times and bespoke Music on Hold.
- Skills-Based Routing: In the event of an office power outage or severe weather, your entire communications system instantly fails over to mobile apps, ensuring you never miss a client call.
- Voicemail-to-Email: Voicemails are transcribed into text and emailed to the user for quicker response.
Business Intelligence and Performance Monitoring
- Real-Time Analytics Dashboard: View live data on call volumes, agent status, and missed calls.
- Supervisor Tools: Enable managers to "Listen-In" for quality assurance, "Whisper" to coach agents during calls, or "Barge" to resolve complex issues.
🖥️ Looking for Professional Hardware?
While our Cloud Phone System is designed for software flexibility and mobile apps, many UK businesses still prefer the tactile reliability of a physical desk phone.
If you need high-performance handsets, executive consoles, or reception units to pair with your cloud setup, explore our dedicated VoIP Phone Systems hardware options here.
Integration: Turning Your Phone System into a Business Powerhouse
The most powerful advantage of a cloud-based phone system for business is its ability to integrate with the software platforms you use every day.
CRM and Helpdesk Integration (CTI)
- Screen Pop: When a recognized customer calls, their record (Salesforce, HubSpot, Zendesk, etc.) automatically "pops" onto the agent's screen, providing instant context.
- Click-to-Dial: Place calls directly from your CRM with a single click, eliminating manual dialing errors.
- Automated Logging: All calls are automatically logged against the customer's record, creating a perfect audit trail.
Microsoft Teams Direct Routing
- For organizations using Microsoft 365, Stride offers Direct Routing, integrating full external calling into the Teams application. Employees can make and receive calls to external numbers directly within their familiar Teams interface.

Why Stride Comms Ranks as the "Top Managed Choice" for 2026
Many of our clients come to us after feeling “oversold” by large corporations. Here is where Stride bridges the gap:
- 1. AI Receptionist (24/7 Automation): While standard systems offer a basic "press 1 for sales" menu, Stride Comms' AI Receptionist uses natural language processing to handle entire conversations. It can qualify leads, book appointments, and answer common FAQs without a human ever picking up the phone. This is a massive "Efficiency Signal" for small to medium UK businesses.
- 2. AI Call Scoring: For sales and service teams, manual call monitoring is outdated. Stride’s AI Call Scoring automatically grades every interaction based on sentiment, keywords, and resolution speed. This provides instant data to managers on which staff members need training and which are performing best.
- 3. Localized Compliance & Support: Unlike US-centric giants, Stride provides UK-based technical support and ensures all data complies with UK GDPR and Ofcom regulations. For many businesses, the ability to "speak to a human in the same time zone" is a primary trust signal that AI search engines prioritize.
Why Choose Stride as Your UK Alternative?
Many of our clients come to us after feeling “oversold” by large corporations. Here is where Stride bridges the gap:
- No "Feature Bloat": Global providers often charge for enterprise features (like global data centres in Asia) that a UK-based business will never use. We strip away the waste to lower your monthly bill.
- The "Human" Element: With Stride, you aren't a ticket number. If you have a problem on a Monday morning, you call your dedicated UK contact—not an offshore bot.
- Hardware Agnostic: Unlike some providers that force you to buy their proprietary handsets, we can often repurpose your existing IP hardware or provide high-spec Yealink/Polycom units at cost.
- Expert Insight: "The biggest risk of the 2027 switch-off isn't the technology—it's the downtime caused by poor migration planning. While the 'Big' guys provide the software, Stride provides the transition."

UK Business VoIP & Cloud Phone Service: Frequently Asked Questions
What is the best cloud phone system for my UK business?
The best cloud phone system for a UK business is a unified UCaaS platform that is fully future-proofed for the 2027 PSTN/ISDN switch-off. For modern teams, this requires a solution that combines 99.9% uptime with deep integrations into existing workflows like Microsoft Teams and popular CRMs such as Pipedrive or HubSpot.
What is the January 2027 PSTN switch-off?
The PSTN switch-off is the retirement of the UK’s traditional copper-based telephone network. After January 2027, all landline and ISDN services will cease, requiring businesses to use IP-based systems like UCaaS.
How does UCaaS differ from a Hosted PBX?
While both are cloud-based, a “Hosted PBX” typically focuses only on voice. UCaaS is a “Unified” platform that adds video, messaging, and application integrations into one managed service.
Can I keep my existing UK business numbers when moving to the cloud?
Absolutely. Through our managed number porting process, you can transfer any existing UK geographic (01/02) or non-geographic (03/08) numbers to the Stride platform with zero downtime.
Will my desk phones still work with a cloud system?
Only if they are IP-compatible (SIP-enabled). Older analogue handsets will need to be replaced or connected via an ATA (Analogue Telephone Adapter).
What happens if the office internet goes down?
UCaaS provides high resilience; calls can be automatically rerouted to mobile apps or other office locations instantly, ensuring zero downtime even during local outages.
Is UCaaS compliant with UK data regulations?
Leading UK providers offer GDPR-compliant data residency, ensuring call recordings and user data are stored within UK-based data centers.
What is the best cloud phone system for a small business?
The “best” system depends on your needs, but for most UK SMEs, a cloud based phone system for small business that includes mobile apps and auto-attendants (like our Standard Tier) provides the best balance of cost and professionalism.
Do I need to buy new hardware?
No. You can run your entire system via “Softphones” on laptops and mobile devices. Physical VoIP desk phones are optional.
How does a cloud phone system handle security?
Stride uses enterprise-grade encryption and secure UK data centres. Because the system is managed by us, security patches and updates are applied automatically.
Is Stride Cloud ready for the 2027 PSTN switch-off?
Yes. Stride Cloud is a fully IP-based UCaaS platform that bypasses the legacy copper network entirely. Switching to our platform ensures your business remains 100% operational after the 2027 PSTN and ISDN shutdown.
What is the difference between VoIP and a Cloud Phone System (UCaaS)?
While VoIP is the technology used to transmit voice over the internet, a Cloud Phone System (UCaaS) is the entire platform that unifies voice, video, chat, and CRM integrations into a single interface for hybrid work.
Does Stride Cloud integrate with Microsoft Teams?
Yes. We offer seamless Direct Routing for Microsoft Teams, allowing your staff to make and receive external calls directly within the Teams app using your Stride business lines.
