T2K VoIP deploys business phone systems throughout Cardiff and South Wales — from Cardiff Bay and the City Centre to the Enterprise Zone and Cathays Park. We're a UK-based VoIP partner with 35+ years telecoms experience, deploying Gamma Horizon, 3CX, Mitel, and all six leading platforms for Cardiff businesses.
Every Cardiff 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 Cardiff businesses, keeping your 029 numbers while moving to modern VoIP.
Cardiff's economy is rapidly evolving, spanning financial and professional services in the City Centre, a thriving creative and media production sector in Cardiff Bay, alongside growing tech, fintech, and life sciences industries. Each sector has specific telephony needs — T2K understands the Welsh capital's dynamic business environment.
As the economic engine of Wales, Cardiff is home to over 14,000 businesses. The city's Central Cardiff Enterprise Zone attracts major financial institutions and legal firms requiring highly secure, compliance-ready communications, while Cardiff Bay serves as one of the UK's most prominent creative and television production hubs.
Cardiff businesses moving from ISDN to VoIP need partners who understand both the city's diverse economy and the technical requirements of migration. T2K VoIP has deployed systems across all Cardiff business districts — from innovative tech startups in the Innovation Matrix to established multi-site enterprises spanning the M4 corridor.
All Cardiff 029 numbers (e.g. 029 20XX XXXX) 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 Cardiff 029 numbers transfer across seamlessly. T2K VoIP manages the full number porting process — no service interruption, no lost calls.
