For decades, businesses have relied on traditional landline phones for communication. However, with advancing technology and the upcoming PSTN switch-off in 2025, many businesses are making the switch to VoIP phone systems.
VoIP (Voice over Internet Protocol) offers lower costs, greater flexibility, and advanced features that traditional landlines simply can’t match. In this blog, we’ll explore why businesses are replacing VoIP and landline phones and how this transition can benefit your company.
The Key Differences Between VoIP and Landline Phones
The key differences between VoiP and Landline Phones include:
1. How They Work
- Landline Phones: Use copper telephone lines to transmit voice signals.
- VoIP Phones: Use the internet to send voice data, allowing calls from any internet-connected device.
2. Cost Comparison
- Landline Phones: Require monthly line rental, expensive call charges, and costly hardware.
- VoIP Phones: Have lower running costs, with free or reduced call rates and no expensive line rental.
3. Features & Flexibility
- Landlines: Limited to basic calling, voicemail, and caller ID.
- VoIP: Offers video calls, call forwarding, voicemail-to-email, mobile integration, and more.
Why Businesses Are Switching from VoIP and Landline Phones
1. The 2025 PSTN Switch-Off
In December 2025, the UK’s Public Switched Telephone Network (PSTN) will be shut down. This means all traditional landline phone services will be replaced with VoIP-based digital solutions. Businesses that rely on landlines must switch to VoIP or risk losing phone service.
2. Significant Cost Savings
Switching to VoIP instead of a landline saves businesses money in several ways:
- No line rental fees – VoIP operates over an internet connection, eliminating costly phone lines.
- Lower call charges – Many VoIP providers offer free UK calls and reduced international rates.
- No expensive hardware – Use existing devices like smartphones, laptops, or VoIP desk phones.
3. Improved Business Flexibility & Remote Work Support
Unlike landlines, which are fixed to a single location, VoIP phone systems provide greater flexibility:
- Make and receive calls from anywhere – Ideal for remote and hybrid workers.
- Call forwarding to mobile devices – Ensures businesses never miss a call.
- Scalable solutions – Easily add or remove users without additional wiring or hardware.
4. Advanced Features for Business Growth
A VoIP phone system provides features that landline phones lack:
- Voicemail-to-email – Receive voicemails directly in your inbox.
- Auto-attendant – Route calls professionally without a receptionist.
- Video conferencing – Host online meetings without extra software.
- CRM integration – Sync calls with customer databases for improved service.
5. Reliability & Future-Proof Technology
Landlines are becoming outdated, while VoIP is the future of communication. VoIP systems:
- Use cloud technology – Preventing downtime due to local infrastructure issues.
- Provide automatic updates – Ensuring businesses always have the latest features.
- Support business expansion – Easily scale up without installing new phone lines.
