VoIP (Voice over Internet Protocol) is a telephone system that routes calls over your internet connection rather than traditional phone lines. Modern cloud VoIP systems include all the features of an expensive on-premise PBX — call queuing, auto-attendant, hunt groups, voicemail to email, call recording — delivered as a monthly subscription per user with no hardware to maintain. With BT's PSTN and ISDN switch-off in January 2027, VoIP is a necessity for every UK business.
VoIP delivers compelling advantages: call costs typically 40–60% lower than ISDN lines, the ability for your team to take business calls on any device from any location, and enterprise features that previously required expensive on-premise hardware. Scaling up for a new team member takes minutes rather than weeks. With the ISDN switch-off deadline approaching, switching is no longer a choice — it is a business requirement.
