Three reasons teams pick Onoff Business as their Aircall alternative

Built for the field

Aircall runs on VoIP and recommends a stable wifi connection. When the network struggles, the app prompts you to move the call to the cellular network. Onoff Business does it automatically.

Everything in one interface

With Aircall, IVR, permissions and routing are configured in Smartflows, a separate module. With Onoff Business, it all sits in the same admin interface. 

Nothing lost when a rep moves on

A rep leaves, an administrator reassigns the number. Call and SMS history stays attached to it.

4,000 companies run their business communications with Onoff Business

FAQ

Yes, for outbound teams: sales reps, account executives, field teams. Onoff Business covers calls, SMS and CRM sync. 

Onoff Business does not replicate Aircall’s inbound contact-centre tooling, such as queue callback or Smartflows routing. Those are built for support desks. If your team calls and texts from the field, you will not miss them.

Yes. Unlike VoIP-only solutions, calls also run over the carrier network. A dropped wifi connection or patchy mobile data does not end the call.

Aircall applies a three-licence minimum on every plan, so a two-person team pays for three seats, and AI features are billed on top. Onoff Business is billed per user, with no minimum. 

Yes. Calls and SMS sync automatically with your CRM depending on your plan (HubSpot from Advanced, Salesforce on Max), so nothing gets lost when a team member leaves or changes role.

The professional number arrives on the phone the employee already uses, with no SIM card or extra device. IVR and routing rules are configured from the admin interface, with no technical setup required.
