Woise vs Retell AI

Retell AI targets mid-market and enterprise buyers by vertical, and leads on compliance certifications. Woise is a smaller, narrower product: a drag-and-drop builder with no attestations of its own. If a certification is a procurement requirement, that decides it before anything else on this page matters.

We make Woise, so read this as an interested party's account. Every statement about Retell AI below links to their own documentation and carries the date we last checked it. If something has changed, their source is the one to trust.

How does the platform connect to the phone network?

Woise

Woise does not sell phone numbers in the US today. You connect a phone number to your agent in the dashboard, and what is available depends on your region.

Retell AI

Retell connects through SIP trunking and supports keeping what you have: "Use your existing phone numbers or your familiar VOIP providers. You can connect to any telephony using Retell SIP Trunking."

What is enforced on an outbound call?

Woise

Do-not-call suppression and per-campaign calling windows are enforced on every dial, in both directions. National DNC scrubbing, 10DLC brand registration and US state attestations are not — those arrive with managed US numbers.

Retell AI

Retell publishes compliance certifications rather than a per-call guardrail list. Ask them which checks run at dial time for your jurisdiction.

Choose Retell AI when

  • Your procurement process requires HIPAA, SOC 2 Type II or GDPR attestations. Woise has none of them, and no amount of product fit changes that.
  • You are buying for a regulated vertical — healthcare, insurance, financial services.
  • You want the vendor to carry more of the compliance weight than you do.

Choose Woise when

  • You want to build and change the call yourself, without an implementation project.
  • Non-engineers need to change what the agent says without waiting on a deploy.
  • You would rather hear every branch in the browser than read about it in a config.
