Phone system

OneBy vs Nextiva

Nextiva is a dependable, well-supported business phone system with a deep feature set. OneBy is a full suite too, but the reason to switch is the AI on top: every call becomes a summary and an assigned task, on its own.

Where Nextiva is genuinely strong

Credit where it's due. Nextiva does some things really well.

  • Mature platform with a strong support reputation
  • Broad feature set and contact-center options
  • Reliable at scale for established businesses
Where OneBy wins

Why teams switch to OneBy

Every call becomes action

Nextiva moves the call. OneBy works the call afterward: it transcribes, summarizes, and creates and assigns the follow-up task automatically.

Pay for AI only where it helps

Put cheap Lines on the phones that just dial and AI seats on the lines that book jobs, instead of one plan priced across every seat.

Live in a day

Port your number, plug in a desk phone, and you're capturing calls the same day. No long onboarding.
