OpenPhone Review

What OpenPhone does

OpenPhone is a modern business phone system built specifically for small teams. The product covers VoIP calling, SMS, voicemail, basic call routing, and shared inboxes for team conversations. It is HIPAA-eligible on the Business tier with a Business Associate Agreement, which makes it usable by ABA agencies that handle PHI in calls and texts.

The company was founded in 2018 and has grown rapidly by being explicitly designed for small teams that find legacy platforms (RingCentral, 8x8, Vonage) over-featured and over-priced. Setup takes minutes rather than hours, and the mobile and desktop apps are consistently rated among the best in the category.

Who it's for

OpenPhone's clearest fit is the solo BCBA or small ABA clinic that wants a real business phone line without the per-user costs and configuration overhead of legacy enterprise platforms. The setup is fast enough that agencies can be on a shared number within an hour of signing up, and the apps are good enough that staff actually use them rather than defaulting to personal cell phones.

It is less ideal for mid-to-large agencies with complex multi-office call routing, dedicated admin lines, or deep CRM integration requirements. OpenPhone's intentional focus on small teams means features like advanced IVR menus, multi-tier call routing, and comprehensive analytics are lighter than what RingCentral or Dialpad offer.

What stands out

The setup speed is the standout. Where RingCentral implementations take a week of configuration, OpenPhone is genuinely live in minutes. For a small clinic that wants a phone line without committing to a project, that speed matters.

The mobile app is the second standout. Operators consistently report that OpenPhone's apps work well enough that the entire team uses them — calls happen on the business number rather than personal cells, voicemails get returned, texts get logged. Compared to legacy platforms where staff often default to personal phones because the official tool is clunky, OpenPhone's app quality is a real operational improvement.

Public pricing and self-serve sign-up complete the picture. No sales calls required.

Where it falls short

The feature set is intentionally narrower. Multi-office routing, advanced call flows, native video meetings, and deep enterprise integrations are not OpenPhone's strengths. Agencies that need those capabilities should look at RingCentral or Dialpad.

HIPAA gating is the same pattern as competitors. The Starter plan does not include the BAA, which means agencies handling PHI in calls or texts need to be on the Business tier minimum. Confirm tier requirements before signing.

The integration ecosystem is thinner than legacy platforms. HubSpot, Salesforce, and Slack integrations exist, but agencies using less-common CRMs or healthcare-specific platforms may find gaps.

Pricing

OpenPhone publishes pricing on the website. Starter plans start at $19/user/month; Business plans (which include the HIPAA BAA) are higher. Confirm current rates and the HIPAA tier at openphone.com/pricing.
