T2K Voice & Data supplies business phone systems, VoIP, SIP trunks and hosted PBX in Cardiff, from professional firms around Central Square and production companies in Cardiff Bay to public-sector bodies in Cathays Park and businesses along the M4 corridor. We're a UK-based telecoms provider with 35+ years' experience, serving customers across the country, Wales included. We set up Gamma Horizon, 3CX, Mitel and three other platforms remotely, and your 029 numbers come with you.
T2K Voice & Data is an independent, UK-based telecoms provider serving customers across the country, Cardiff included. Hosted systems are built and tested before go-live, handsets arrive pre-provisioned, and 029 numbers port across through the network, so most Cardiff projects need nobody on site. If yours does, we'll agree it before you sign.
We supply the full telecoms stack for Cardiff businesses: cloud phone systems, on-premise PBX, SIP trunks, Microsoft Teams calling, business broadband, leased lines and mobiles. One supplier and one support line.
As the Welsh capital, Cardiff combines financial, legal and professional services around Central Square and the city centre with TV and media production in Cardiff Bay, a growing fintech and tech scene, life sciences linked to the universities and Heath Park, and a large public sector based around Cathays Park.
Financial and legal firms usually need compliant call recording and consistent caller ID across offices. Production companies and agencies in Cardiff Bay want softphones and video alongside calls, so crews and freelancers can stay reachable on set or on the move.
Public bodies, universities and healthcare providers need call queues, bilingual auto-attendants and reliable reporting. Many Cardiff businesses also have sites across the M4 corridor and the Valleys, where one hosted platform can link every office on a single system.
Every Cardiff 029 number can move to a VoIP phone system or divert straight to a mobile. Callers across Cardiff and the Vale of Glamorgan keep dialling the same number.
Moving to Gamma Horizon, 3CX or Mitel, or simply want calls on your mobile? Your 029 number comes with you either way. T2K Voice & Data handles the porting, with no gap in service.
