Seamless Microsoft Teams Phone Systems for UK Business

UNIFIED COMMUNICATIONS

STRATEGIC BUSINESS ADVANTAGES

Why replace your desk phone with Microsoft Teams?

Consolidate your communication stack and future-proof your business. By moving your telephony to the Microsoft Cloud, you eliminate expensive UK line rentals, scrap outdated hardware maintenance costs and prepare for the 2027 PSTN switch-off. Empower your staff to make and receive business calls using their 01, 02, or 03 numbers from any device, whether they are in the office, working from home, or anywhere in the world.

Flexible UK Connectivity & Direct Routing

Your UK office number follows you everywhere. Whether you're working from a home office in London, commuting on the train, or at your desk, our Direct Routing ensures you never miss a client call. We handle the transition from your current UK provider with zero downtime.

Empower Your UK Hybrid Workforce

Give your team the freedom to work from anywhere in the UK or abroad. By integrating your phone system into the Microsoft Teams app, staff can make professional business calls using their company number on any device, reducing the need for expensive mobile contracts and hardware.

Next-Gen UK Cloud PBX Features

Replace your aging hardware with a feature-rich cloud system. Benefit from professional UK auto-attendants (IVR), intelligent call queues, and voicemail-to-email—all managed via the simple Teams Admin Centre. Perfect for businesses preparing for the January 2027 PSTN switch-off.

ENTERPRISE VOICE FEATURES

Everything you need to retire your old phone system

0800

Keep your existing 01, 02, or 0800 numbers. We manage the full migration and carrier liaison. We ensure zero downtime during porting, so your business remains fully connected and operational throughout the switch.

2027

ISDN & PSTN END OF LIFE

The UK’s legacy copper network is officially retiring. By 2027, all traditional ISDN and PSTN lines will be deactivated. Your business must migrate to a digital (IP) connection to stay operational.

"The PSTN Switch Off is coming in 2027. Moving your voice to Microsoft Teams isn't just an upgrade; it is the smartest way to future-proof your business against the deactivation of traditional phone lines."
