VoIP & Telephony for Cardiff Businesses

Cardiff businesses range from one-person consultancies in Pontcanna to call-handling teams in the city centre β€” and the BT PSTN switch-off in 2027 affects every one of them. VoIP is the replacement, and done properly it is cheaper and more flexible than the lines it replaces.

Thorne Technology designs and deploys cloud phone systems for Cardiff businesses, from sole traders running 1–2 numbers to multi-site offices with hundreds of users. We resell from established UK VoIP platforms, supply Yealink and Polycom handsets, and configure everything to fit how your team actually works.

What's included

Cloud-Hosted Phone System No on-site PBX hardware. Your phone system lives in the cloud, accessible from any device, anywhere.
Desk Phones and Softphones Real handsets, mobile apps, or both. We configure each user the way they prefer to work.
Call Recording and Routing Record any line for compliance or training. Route calls by time of day, by who is available, or to mobiles when you are out.
Number Porting Keep your existing Cardiff numbers when you switch. We manage the porting process with your current provider.
Microsoft Teams Integration Make and receive PSTN calls inside Teams. Replace your phone system with Teams Voice if it suits how your business works.
No Long Contracts Per-user, per-month pricing. Add or remove users as your team changes. No five-year tie-ins.

What sets us apart for Cardiff businesses

PSTN switch-off ready

BT is retiring traditional phone lines in 2027. We have already migrated dozens of Cardiff businesses to VoIP, so we know how to do it without losing any calls.

Quality handsets, fair pricing

We supply trade-quality Yealink and Polycom handsets at honest prices, not consumer-grade kit dressed up for businesses.

Full configuration included

Hunt groups, IVR menus, voicemail-to-email, after-hours routing β€” all set up the way you actually want them, not whatever the default is.

Common questions from Cardiff businesses

A typical Cardiff business pays Β£7-Β£15 per user per month for the platform, plus Β£100-Β£200 once for a desk phone (or use a free softphone). For most businesses, switching from BT lines saves money from month one.
Yes. We port them across as part of the migration β€” no need to change your stationery, signs or website. The number stays the same; just the underlying technology changes.
Calls automatically forward to mobile numbers, or to any other site, until the connection comes back. We can also configure 4G/5G failover to keep the office line alive during a fixed-line outage.
Yes. Selective or all-call recording, with retention periods to suit your industry β€” including stricter rules for financial services or healthcare.
