T2K Voice & Data supplies business phone systems in Southampton, from port and maritime businesses around the docks to professional firms in the city centre, healthcare and research teams near the universities, and businesses across Eastleigh, Totton and the Waterside. 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, and your 023 numbers come with you.
T2K Voice & Data is an independent, UK-based telecoms provider serving customers across the country, Southampton and Hampshire included. Hosted systems are configured and tested before go-live, handsets arrive pre-provisioned and 023 numbers port across through the network. Where a site needs an engineer, such as dockside DECT coverage or an on-premise PBX swap, we plan the visit with you.
We supply the full telecoms stack for Southampton businesses: cloud phone systems, on-premise PBX, SIP trunks, Microsoft Teams calling, business broadband, leased lines and mobiles, all on one contract.
Southampton is a major port city and the UK's busiest cruise port, with a large marine and maritime sector around the docks and along Southampton Water. Healthcare and medical research, two universities, retail and professional services in the city centre round out the economy.
Shipping, freight and marine businesses need calls that follow staff around terminals and yards, plus ring groups and out-of-hours routing for round-the-clock operations. Healthcare and research organisations need reliable queues, recording and clear routing for patients and partners.
Retailers, hotels and hospitality venues in the city centre need call handling that copes with cruise-day and seasonal peaks, while accountants and solicitors want call recording and consistent caller ID. Moving off analogue or ISDN lines follows the same steps for all of them.
Every Southampton 023 number can move to a VoIP phone system or divert straight to a mobile. The 023 code also covers Portsmouth, so businesses across South Hampshire share a recognisable local number.
Keep the number your customers know. We port 023 numbers onto whichever platform you choose, or simply divert them to a mobile, and your old line stays live until the switch.
We work with six business telephone system platforms, from fully hosted VoIP to on-premise PBX, and recommend what fits your operation for Southampton firms rather than pushing one vendor.
