A SaaS web application providing VoIP phone services for BT customers, enabling landline on the go. I worked on all UI and took over UX for the project.
Unique users
Weekly calls
Increase in call numbers
Increase in app usage
We clarified business goals and constraints, then mapped a service structure aligned with feasibility.
(Business proposition: What we’re selling and how customers access it.)
(Service design: Structure of the cloud‑based product.)
With the underlying structure mapped, we designed UX flow and UI for the portal, prototyping conditional logic and error states in Axure (best viewed on desktop; fonts may differ).
(Device management user flow: Exact journey mapping.)
(Hardware & software requirement: Upfront constraints to avoid build issues.)
(Product mockup: High‑level product overview.)



The app pairs with the portal to offer VoIP landline on the go.
