Brighton & Hove Business Telephone Systems, Set Up Remotely

T2K Voice & Data is an independent, UK-based telecoms provider serving customers across the country, Brighton and Hove included. Hosted systems are configured and tested before go-live, handsets arrive pre-provisioned and 01273 numbers port across through the network, so most Brighton projects need no engineer on site. If yours does, we'll agree it before you sign.

We supply the full telecoms stack for Brighton and Hove businesses: cloud phone systems, on-premise PBX, SIP trunks, Microsoft Teams calling, business broadband, leased lines and mobiles. One supplier and one support line.

Brighton & Hove's Business Landscape & What It Needs from a Phone System

Brighton and Hove has one of the South Coast's biggest clusters of digital, creative and software businesses, often called 'Silicon Beach', alongside a large visitor economy, two universities and professional services firms in central Hove and the city centre.

Agencies and software companies usually want softphones, Microsoft Teams calling and CRM integration so staff can work from the studio, home or a co-working desk on the same 01273 number. Many are growing fast, so they need a system that adds users in minutes.

Hotels, restaurants and venues along the seafront need call handling that copes with summer and event peaks, while solicitors, accountants and estate agents in Hove need call recording and consistent caller ID. Moving off ISDN or analogue lines follows the same steps for all of them.

Sussex Deployment
South Coast Nursing Homes — 10 Sites, One 3CX System
South Coast Nursing Homes needed to bring fragmented phone systems across nine care homes and a head office in Sussex onto one platform, after a previous supplier's rollout had stalled. T2K Voice & Data took over the project and deployed a single hosted 3CX system for nearly 500 extensions across all 10 sites, keeping familiar analogue handsets for residents and keeping downtime to a minimum.

FAQ

Business Phone Systems & VoIP in Brighton & Hove — Frequently Asked Questions

Questions we regularly hear from Brighton & Hove businesses comparing VoIP providers and phone systems.

Can I keep my Brighton 01273 phone numbers when switching to VoIP?
Yes. 01273 numbers can be ported to any of the six platforms we supply. We handle the paperwork with your current provider, and your existing line keeps working until the moment it switches over.
Do you provide on-site support for Brighton businesses?
Most Brighton phone systems are installed and supported remotely, and most faults are fixed over a remote session. Where a visit is genuinely needed, such as a multi-floor DECT install or an on-premise PBX, we plan it with you and confirm it before you sign.
How much does a business phone system cost in Brighton?
Hosted platforms such as Gamma Horizon or 3CX typically cost around £10–£20 per user per month for a Brighton business with 5–50 users. Care groups, multi-site organisations and larger firms usually suit Mitel or 3CX on custom pricing, and every quote is itemised.
How long does a VoIP migration take for a Brighton business?
Timescales depend on size: most single-site Brighton businesses are live within a couple of weeks, multi-site rollouts within 4–8 weeks. We plan the cutover for evenings or weekends.
Can a phone system handle staff working from home and the studio?
Yes. With softphone apps for desktop and mobile, staff take and make calls on your 01273 number wherever they are, with the same queues, transfers and call recording as the office.
Do Brighton businesses need to replace analogue and ISDN phone lines?
Yes. Openreach is retiring the UK's traditional PSTN and ISDN network, including every exchange in Brighton, Hove and Sussex, so businesses still on analogue lines, ISDN2 or ISDN30 need to move to VoIP, SIP trunks or a digital line replacement. Check where your lines stand with our PSTN switch-off checker.
