T2K Voice & Data supplies business phone systems in Portsmouth, from tech and professional services firms at Lakeside North Harbour to defence and engineering suppliers serving the naval base, and retailers and hospitality venues in Southsea and around Gunwharf Quays. 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, Portsmouth 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 workshop DECT or an on-premise PBX swap, we plan the visit with you.
We supply the full telecoms stack for Portsmouth businesses: cloud phone systems, on-premise PBX, SIP trunks, Microsoft Teams calling, business broadband, leased lines and mobiles. One supplier and one support line.
Portsmouth is home to HM Naval Base Portsmouth and a wide marine, defence and engineering supply chain. Lakeside North Harbour in Cosham is one of the area's largest office parks, and retail, tourism and hospitality are concentrated in Southsea, Gunwharf Quays and the historic waterfront.
Defence and engineering suppliers usually need secure, resilient communications, call recording and ring groups that reach workshops and project teams. Tech and professional services firms at Lakeside and in the city centre want softphones, Microsoft Teams calling and consistent caller ID across offices.
Retailers, hotels and attractions need call handling that copes with summer and event peaks. Many businesses along the M27 corridor also have sites in Fareham, Havant or Southampton, where one hosted platform can link every office on a single system.
Every Portsmouth 023 number can move to a VoIP phone system or divert straight to a mobile. 023 is shared with Southampton, so businesses across South Hampshire keep a recognisable local number.
Your 023 number isn't tied to a copper line. It can move to Gamma Horizon, 3CX, Mitel or a mobile divert, and T2K Voice & Data handles the port from start to finish.
From hosted VoIP to an on-premise PBX, T2K Voice & Data supplies six platforms to Portsmouth firms. Because we aren't tied to any of them, we recommend what suits your sites and security needs.
Hosted on Gamma's UK network, Horizon gives Portsmouth offices auto-attendants, hunt groups and voicemail-to-email out of the box, with no on-site PBX.
A software IP PBX with deep CRM integration, popular with Lakeside tech and professional services teams. T2K Voice & Data is a 3CX Titanium Partner.
An enterprise unified communications platform for larger Portsmouth organisations, including engineering and defence suppliers needing on-premise control and resilience. T2K has decades of Mitel experience.
Cisco Webex calling, meetings and messaging over Gamma's UK carrier network. Suits project teams working across sites and from home.
A straight swap for an analogue line, ideal for a Southsea shop, guest house or small office. Your 023 number and current handset stay put, and the service runs over your broadband instead.
A flexible UCaaS platform with calls, messaging and meetings in one app. A good match for Portsmouth firms running on Microsoft 365.
