What is VoIP?
VoIP (Voice over Internet Protocol) is a phone system that routes calls over your internet connection rather than a copper telephone wire. The technical mechanism is different, but the end result for your customers is identical — they call your number, you answer. The call quality on a good broadband connection is indistinguishable from a traditional landline.
Where VoIP differs is in everything else: cost, flexibility, features and scalability.
Cost Comparison
This is where VoIP wins most decisively. Consider a typical Wolverhampton business with 5 phone lines:
Features Comparison
Traditional ISDN gives you what you had in 1995: a dial tone. VoIP gives you a complete communications platform:
- ✓ Auto-attendant and IVR menus ("Press 1 for sales...")
- ✓ Call recording and transcription
- ✓ Call queuing and music on hold
- ✓ Voicemail to email
- ✓ Mobile app — works from any device, anywhere
- ✓ Video conferencing built in
- ✓ CRM integration
- ✓ Call analytics and reporting
- ✓ Number porting — keep your existing number
- ✓ Add or remove users instantly from a web portal
The 2027 Deadline — Why This Decision is Time-Sensitive
BT is switching off the entire PSTN and ISDN network permanently in January 2027. This is not a recommendation — it is a hard cutoff. If your Wolverhampton business is still on a traditional landline in 2027, your phone will stop working.
BT has already implemented a Stop Sell — you cannot get new ISDN lines in most UK exchanges. Area-by-area switch-offs are already happening across the UK.
The practical advice: switch to VoIP now, while you can plan calmly, rather than rushing in 2026 when installation slots will be severely limited.
