A VoIP (Voice over Internet Protocol) phone system is the essential modern infrastructure that converts analogue voice signals into digital data packets and transmits them over the internet, bypassing traditional copper phone lines (PSTN/ISDN). This technology offers enhanced features, flexibility for remote work, and significant cost reductions (30-60%) compared to legacy systems
What Exactly is a VoIP Phone System?
Why Traditional Phone Systems Are Holding UK Businesses Back
The Hidden Costs and Limitations of Outdated Telephony
PSTN/ISDN Switch-Off Deadline
- 2027 is closer than you think: BT Openreach is decommissioning all PSTN and ISDN lines by January 2027
- No new analogue installations: Traditional phone lines are already unavailable in many areas
- Migration complexity: Last-minute switches will face installer shortages and premium pricing
Financial Drain
- Line rental costs £15-30 per line/month: Multi-line businesses pay hundreds monthly before making a single call
- Per-minute call charges: Typical 5-15p/minute rates add up quickly
- Limited scalability: Adding new users requires physical line installations (£200-500 per extension)
The question is whether you upgrade proactively on your terms, or reactively under pressure.

Remote Working - Mobile Calling app
A dedicated application for smartphones and tablets (iOS, Android) that extends the capabilities of a VoIP phone system to mobile devices. It enables users to make and receive calls using their business number, access company directories, manage voicemails, and set call forwarding, even when away from the office. This feature ensures business continuity and accessibility, empowering employees to stay connected and productive from any location with an internet connection.
Core VoIP Features
These are the fundamental capabilities that define a functional VoIP phone system. They include essential communication tools like inbound and outbound voice calling, internal extension dialing, and intelligent call routing to direct calls efficiently. Core features also encompass voicemail with options like voicemail-to-email, call hold and transfer functionalities, caller ID for identifying callers, call waiting notifications, and Do Not Disturb settings, ensuring basic yet comprehensive telephony operations for any business.
Advanced Team Management and Features
Our VoIP systems go far beyond these core capabilities. We provide advanced functionality that empowers your managers and contact centre supervisors, including enterprise-grade tools for staff enablement and agent performance.

CRM Integration (VoIP Systems)
This powerful feature connects the VoIP phone system directly with Customer Relationship Management (CRM) software like Salesforce or HubSpot. Key functionalities include screen pops, where caller information automatically appears upon an incoming call, and click-to-call, allowing dialing directly from the CRM. It also automates call logging and activity tracking, ensuring every customer interaction is recorded, and synchronizes contact data. This integration streamlines workflows, enhances efficiency, and provides agents with critical context, significantly improving customer service and sales processes.
Business Portal (VoIP Management)
A secure, web-based dashboard designed for administrators and users to manage the VoIP phone system’s settings and features. Administrators can easily perform user management (add/edit users), configure intricate call flows (auto-attendants, routing rules), and access comprehensive reports and analytics on call activity. Individual users can manage personal settings like voicemail greetings and call forwarding. The portal provides full control and visibility, enabling quick adjustments and efficient management without constant reliance on IT support or the service provider.

VoIP vs Traditional Phone Systems: Side-by-Side Comparison
Stride Communications Ltd delivers modern, scalable VoIP solutions that outperform traditional phone systems on every key metric. Unlike legacy PSTN/ISDN lines, which rely on costly physical infrastructure and lack flexibility, VoIP phone systems use the internet to provide cost-effective, feature-rich, and future-proof telephony.
| Factor | VoIP Phone System | Traditional Phone System (PSTN/ISDN) | Winner |
|---|---|---|---|
| Monthly Cost (20 users) | £240-500 all-inclusive | £600-1,000+ (line rental + call charges) | ✅ VoIP |
| Setup Time | 1-5 days (mostly remote) | 2-4 weeks (engineer-dependent) | ✅ VoIP |
| Scalability | Add users in minutes via web portal | Requires engineer visit, 1-2 weeks lead time | ✅ VoIP |
| Remote Work Support | Native (mobile/desktop apps, free remote calling) | Expensive workarounds (call forwarding fees) | ✅ VoIP |
| Call Quality | HD voice (G.722 codec), excellent with good internet | Standard voice quality | ✅ VoIP |
| Advanced Features | Included (recording, analytics, CRM, auto-attendant) | Expensive add-ons or impossible | ✅ VoIP |
| Multi-Site Support | Seamless (single system, free inter-site calls) | Complex (separate systems, call charges between sites) | ✅ VoIP |
| Emergency Calling (999) | Supported (location data required) | Automatic location detection | ⚖️ Equal |
| Internet Dependency | Requires reliable broadband (risk mitigated with 4G backup) | Independent of internet | ⚠️ Traditional |
| Power Outage Impact | Requires power (UPS recommended) or mobile failover | Some phones work during power cuts | ⚠️ Traditional |
| Future-Proofing | Aligned with industry direction | Being phased out (2027 switch-off) | ✅ VoIP |
| Migration Path | Stable, evolving technology | No future—forced migration by 2027 | ✅ VoIP |
Hybrid Option: Many businesses transition gradually: Start with VoIP for new users/sites while maintaining traditional lines for a defined period, then migrate fully once confidence builds.
The Reality: Traditional phone systems are a sunset technology. The 2027 PSTN switch-off means every UK business will eventually use VoIP. The only question is whether you migrate proactively (on your schedule, with preparation) or reactively (rushed, expensive, limited choices).

Frequently Asked Questions
Comprehensive Answers to Your VoIP Questions
Can I keep my existing phone number?
Yes. UK regulations require number porting for all geographic (01/02/03) numbers. The process typically takes 10-15 working days with no downtime.
What happens if my internet goes down?
Modern VoIP systems include failover options: mobile app failover, call forwarding to mobile numbers, and 4G backup routers for business-critical environments.
How much does a business VoIP system cost?
Typical per-user costs: £12-30/month depending on features. Example for 20 users: £240-600/month total (vs £600-1,000+ for traditional system).
Is VoIP call quality as good as traditional lines?
With good internet: Yes, often better. VoIP supports HD voice (G.722 codec) which provides noticeably clearer audio than standard phone lines.
What happens in 2027 with the PSTN switch-off?
BT Openreach is decommissioning all traditional analogue phone lines by January 2027. By switching to VoIP now, you avoid the 2026-2027 rush and start saving money immediately.
