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.
This is where VoIP wins most decisively. Consider a typical Wolverhampton business with 5 phone lines:
Traditional ISDN gives you what you had in 1995: a dial tone. VoIP gives you a complete communications platform:

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.
Switching to VoIP with Telexico takes three steps:
→ VoIP phone systems in Wolverhampton — from £9.99/user/month
→ PSTN 2027 switch-off — check if your business is affected
