How to Switch from Landline to VoIP: A Practical Guide for Businesses
Leased Line vs Broadband
September 6, 2026
Switching in Cardiff and South Wales Local context matters. Buildings in the city centre, Cardiff Bay and older stock can have patchy indoor signal and mixed cabling. A provider who will survey the site, install data cabling and Wi-Fi, and stay for support is more useful than a remote portal and a box of phones. Crystal Voice Data helps businesses across Cardiff and South Wales move from landline to VoIP as part of a wider package: VoIP phone systems, cloud phone systems, leased lines, business broadband, Wi-Fi and data cabling, plus installation, training and ongoing support. Ready to plan the switch? If you are still on landline or ISDN, the useful question is not whether to move to VoIP — it is when, and how cleanly. Start with a site survey and a list of every number and analogue device you have. From there you can choose a cloud phone system that keeps your 029 numbers, works with the way your team already works, and is ready before the PSTN switch-off. Get in touch for a straightforward assessment of your current lines and what a VoIP cutover would look like for your office.
