One number on your desk phone and mobile
Fusion One puts your desk phone and mobile on one business number. Move a call between devices mid-call, with one bill and one point of contact.
Field Teams
Engineers and sales staff take office calls on their mobile, showing the business number, not their personal one.
Remote Workers
Staff at home answer the main line as if they were in the office.
Growing Teams
Add a user in minutes. No new lines, no extra hardware.
How it works
From first call to go‑live

Your business number on each person's desk phone and mobile.

You're live
Customers call one number and reach the right person, wherever they are.
Works with Fusion Nexus
Fusion One links your mobiles into the Fusion Nexus cloud phone system, so calls, video meetings and messaging follow your team between desk phone, laptop and mobile.
"They gave us the peace of mind to focus on our launch, knowing our connectivity was in expert hands."
