Microsoft Teams Calling: Everything Bristol Businesses Need to Know

Severn Business SystemsBristol8 February 2026Guide

If your business already uses Microsoft Teams for meetings and chat, you might be wondering: can we use it as our phone system too?

The answer is yes — and we've helped over 50 Bristol businesses make the switch.

How it works: Gamma Horizon provides "direct routing" — connecting Teams to the phone network so you can make and receive regular phone calls through the Teams app.

Benefits:

  • One app for calls, meetings, and messages
  • No desk phones needed (use PC, mobile, or Teams-certified handsets)
  • Keep your existing phone numbers
  • Call recording and advanced analytics included
  • Works from anywhere — office, home, or on the road

What does it cost? From £9.50 per user/month for unlimited UK and mobile calls. No handsets to buy if you use softphones.

Requirements:

  • Microsoft 365 Business or Enterprise licence
  • Reliable broadband (minimum 100kbps per concurrent call)

We offer a free Teams telephony consultation for Bristol and South West businesses. Book yours at severnbusiness.example.com or through TendorAI.
