T2K Voice & Data supplies business phone systems in Sheffield, from city-centre professional firms and Kelham Island studios to engineering and manufacturing businesses in the Lower Don Valley and around the Advanced Manufacturing Park. We're a UK-based telecoms provider with 35+ years' experience, serving customers across the country. We configure Gamma Horizon, 3CX, Mitel and three other VoIP platforms remotely, and your 0114 numbers come with you.
As an independent, UK-based provider serving customers across the country, T2K Voice & Data supports plenty of businesses in Sheffield without needing to be on the doorstep. Platforms are set up centrally, handsets arrive pre-configured and 0114 numbers move across through the network, so most Sheffield installations happen without a visit. Where one is needed, such as DECT coverage in a workshop or factory, we agree it before you sign.
We supply the complete telecoms stack for Sheffield businesses: cloud phone systems, on-premise PBX, SIP trunks, Microsoft Teams calling, business broadband, leased lines and mobiles. One supplier, one bill and one support line.
Sheffield's economy still has making at its heart, with precision engineering, steel and advanced manufacturing along the Lower Don Valley and at the Advanced Manufacturing Park on the Rotherham border. Alongside that sit digital and creative businesses in Kelham Island and the city centre, a large healthcare and university sector, and professional services around the Cathedral Quarter.
Engineering and manufacturing firms usually need phones that reach people on the shop floor: rugged DECT handsets, paging, ring groups and calls that follow supervisors between buildings. Many still run an ageing on-premise PBX on ISDN lines, which makes a planned move to hosted VoIP or SIP trunks a priority.
Digital agencies and tech start-ups want softphones and Microsoft Teams calling so staff can work anywhere on the same 0114 number. Healthcare providers and professional practices need call queues, recording and reliable caller ID. Whatever the sector, the move follows the same steps: audit, choose a platform, port your numbers and cut over out of hours.
Every Sheffield 0114 number can move to a VoIP phone system or divert straight to a mobile, so customers keep calling the number they already know.
Your 0114 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.
We work with six business telephone system platforms, from fully hosted VoIP to on-premise PBX, and recommend what suits your sites and shift patterns for Sheffield firms rather than pushing one vendor.
The UK's most widely used hosted phone system, on Gamma's own UK network. A safe choice for Sheffield offices and practices that want cloud telephony with nothing to maintain.
A software IP PBX with deep CRM integration, popular with Sheffield sales and service teams using HubSpot, Salesforce or Zendesk. T2K Voice & Data is a 3CX Titanium Partner.
An enterprise unified communications platform for larger South Yorkshire organisations, including manufacturers that need on-premise control and multi-site call routing. T2K has decades of Mitel experience.
Cisco Webex calling, meetings and messaging over Gamma's UK carrier network. Suits Kelham Island studios and hybrid teams working between home and the office.
The low-cost route off copper for a Sheffield shop, workshop or small office. No new phones and no engineer visit: your 0114 number simply moves onto a digital line.
A flexible UCaaS platform with calls, messaging and meetings in one app. A strong match for Sheffield firms already standardised on Microsoft 365.
