Microsoft Teams Calling

Turn Microsoft Teams into a fully featured business phone system.

With FX Business Technologies, you can make and receive external phone calls directly inside the Microsoft Teams app, on desktop, mobile, or certified Teams handsets. No separate phone system, no extra software, no switching between tools. Just one platform for messaging, meetings, and voice.

What Is Microsoft Teams Calling?

Microsoft Teams Calling allows your organisation to use Teams as a cloud-based phone system, replacing traditional desk phones and on-premise PBX hardware. When paired with Direct Routing or a Calling Plan, your team can make and receive calls to the public phone network, just like a normal phone system, but powered by the cloud.

Why Businesses Are Moving to Teams Calling

  • Cuts the cost of owning, maintaining, and eventually replacing PBX hardware
  • Supports hybrid workforces without VPNs, call forwarding, or extra licences
  • Centralises communication into a single Microsoft ecosystem users already know
  • Makes ICT management leaner (one platform, one login, one security model)
  • Turns voice into a scalable cloud service instead of a fixed hardware asset

 Replace Your Phone System, Not Your Workflow

Already using Microsoft 365? With FX Business Technologies, you can turn your existing licence into a complete voice platform, cutting costs, simplifying ICT management, and giving users a single app for all communication.
