Why teams switch to OneBy

A full suite, not just an app

OneBy adds desk phones with auto-provisioning and online fax, so you can retire the old phone system entirely, not just the softphone.

Calls turn into tasks, automatically

OpenPhone records and can transcribe. OneBy goes the last mile: it summarizes every call and creates and assigns the follow-up task for you.

Built for businesses that dispatch

Field teams, front desks, and on-call routing are first-class. The AI receptionist captures jobs when nobody can pick up.
