1. Traditional Landlines
For decades, landlines were the go-to for business telephony. However, with BT set to switch off the Public Switched Telephone Network (PSTN) by the end of 2025, analogue systems are rapidly becoming obsolete.
Pros:
- Familiar, simple setup
- Historically reliable
Cons:
- Expensive line rental and limited flexibility
- No scalability or remote working support
- Becoming unsupported and increasingly costly to maintain
Verdict:
If you’re still using a traditional landline system, now is the time to plan your migration.
2. Mobile Phones
they’re handy, they’re not a comprehensive business phone system.
Pros:
Mobility and availability
No installation required
Cons:
Lacks call routing, recording, reporting or team management features
Calls often made from personal numbers
Inconsistent call quality and poor professional image
Verdict:
Great for flexibility, but unsuitable as a primary phone system for most businesses.
3. VoIP Phone Systems
VoIP (Voice over Internet Protocol) allows you to make and receive calls over your internet connection instead of traditional copper phone lines. These systems are ideal for small to mid-sized businesses seeking flexibility, reliability, and professional features — without a large upfront investment.
Pros:
No hardware or setup fees
Scalable and easy to manage
Includes advanced features like auto-attendants, call recording, and analytics
UK landline and mobile calls often included in monthly cost

Verdict:
A modern, cost-effective solution that future-proofs your communications.

4. Unified Communications (UC) Platforms
