T2K Voice & Data supplies business phone systems in Oxford, from life sciences and tech companies at the Oxford Science Park, Headington and Begbroke to engineering and manufacturing firms in Cowley, publishers in the city centre and businesses across Abingdon and Kidlington. We're a UK-based telecoms provider with 35+ years' experience, serving customers across the country. We set up Gamma Horizon, 3CX, Mitel and three other VoIP platforms remotely, and your 01865 numbers come with you.
As an independent, UK-based provider serving customers across the country, T2K Voice & Data supports plenty of businesses in Oxford without needing to be on the doorstep. Platforms are set up centrally, handsets arrive pre-configured and 01865 numbers move across through the network, so most Oxford installations happen without a visit. If yours does, we'll agree it before you sign.
Alongside cloud and on-premise phone systems, we provide the connectivity they rely on, from business broadband and leased lines to mobiles and SIP trunks, so Oxford customers have a single supplier to call.
Oxford's economy is anchored by its university and hospitals, with a fast-growing life sciences and deep-tech sector at the Oxford Science Park, Headington and Begbroke, car manufacturing and engineering at Cowley, a long publishing tradition, and professional services across the city and county.
Life sciences and tech spin-outs usually work in hybrid teams and grow quickly, so they want softphones, Microsoft Teams calling and a system that scales. Research and healthcare organisations need reliable routing across several buildings.
Engineering and manufacturing businesses in Cowley need rugged handsets and ring groups for production areas, while publishers and professional firms need call recording and consistent caller ID. Moving off ISDN or analogue lines follows the same steps for all.
Every Oxford 01865 number can move to a VoIP phone system or divert straight to a mobile, so customers across Oxford and nearby towns keep calling the number they know.
Moving to Gamma Horizon, 3CX or Mitel, or just want calls on your mobile? Your 01865 number comes with you either way. T2K Voice & Data handles porting end to end, with no gap in service.

An enterprise unified communications platform for larger Oxfordshire organisations, including manufacturers needing on-premise control. T2K has decades of Mitel experience.
Cisco Webex calling, meetings and messaging over Gamma's UK carrier network. Suits research teams collaborating across sites.
The low-cost route off copper for an Oxford shop, practice or small office. No new phones and no engineer visit: your 01865 number simply moves onto a digital line.
