T2K VoIP deploys business phone systems throughout Oxford and Oxfordshire — from the Oxford Science Park and Cowley to the City Centre, Headington, and Begbroke. We're a UK-based VoIP partner with 35+ years telecoms experience, deploying Gamma Horizon, 3CX, Mitel, and all six leading platforms for Oxford businesses.
Every Oxford business still using traditional landlines or ISDN must migrate to VoIP by December 2027. Openreach is switching off the UK's PSTN network — businesses that don't migrate will lose phone service. T2K VoIP specialises in zero-downtime migrations for Oxford businesses, keeping your 01865 numbers while moving to modern VoIP.
Oxford's economy spans world-leading education and research, cutting-edge life sciences (Oxford Science Park), advanced automotive manufacturing (Cowley), and publishing. Each sector has specific telephony needs — T2K understands Oxford's unique position as a global centre for knowledge and innovation.
As a vital anchor of the 'Oxford-Cambridge Arc', Oxford supports thousands of businesses driving the UK's knowledge economy. The city is celebrated for its deep-tech startups and biotech spin-outs emerging from the university, which require highly secure, ultra-fast, and scalable cloud-based communications.
Oxford businesses moving from ISDN to VoIP need partners who understand both the city's prestigious academic heritage and the technical requirements of a seamless digital migration. T2K VoIP has deployed systems across all Oxford business districts — from innovative research labs in Headington to advanced engineering facilities on the city's outskirts.
All Oxford 01865 numbers can be ported to VoIP systems with zero gap in service. Your clients and customers continue calling the same numbers — the only change is the underlying technology.
Whether you're moving to Gamma Horizon, 3CX, Mitel, or any other platform, your existing Oxford 01865 numbers transfer across seamlessly. T2K VoIP manages the full number porting process — no service interruption, no lost calls.
