BT plans to complete its PSTN and ISDN switch-off by 31st January 2027, which means that every UK business using legacy phone lines will need to plan for a move over to a digital solution, and SIP trunking is the suggested migration path.<\/p><p>In the UK, SIP trunk providers allow you to take your existing PBX phone system and migrate your voice calls across the internet. You improve call quality, reduce recurring expenses every month, and can simply scale channels up or down when your business requirements change.<\/p><p>However, not all SIP trunk providers are the same. Since every provider is different in terms of pricing structures, compatibility with PBX systems, whether or not they have UK numbers available, and other factors, finding the ideal VoIP solution can take quite a bit of time.<\/p><p>In this guide, ComparedBusiness UK has ranked the top 9 SIP trunk providers in the UK for comparison in 2026.

If a business has to handle 10 calls at the same time, then it requires 10 channels. To calculate your base start, measure the number of your maximum concurrent calls and increase by 20%.
