Which States Require All-Party Consent to Record Calls, and What Does That Mean for AI?

By Manny Larcher

An AI phone agent can't work without listening, and most also record, transcribe, and summarize each call. That puts every deployment inside a body of law written long before AI: state wiretap and eavesdropping statutes. For businesses that take calls from across the country, the strictest law sets the bar.

One-party vs. all-party consent

Federal law requires at least one party's consent to record a call. Most states follow that rule. But the Reporters Committee for Freedom of the Press counts about 11 states that primarily require all-party consent. Its long-standing list includes California, Florida, Illinois, Maryland, Massachusetts, Montana, New Hampshire, Pennsylvania and Washington. Connecticut and Nevada apply all-party consent specifically to phone calls, while Missouri and Oregon apply it only to in-person conversations. Courts have read some statutes, including Michigan's, in conflicting ways.

When a call crosses state lines, the common practice is to follow the stricter state's rule.

Why AI raises the stakes

Courts are now testing how these laws apply to AI. In July 2026, a federal judge dismissed a class action claiming that AI analysis of a dental group's patient calls violated the federal Wiretap Act, but state recording laws are a separate question. Courts keep returning to whether callers knew a recording was being made and who else had access to it.

How to stay on the right side

1. Announce it at the start. A brief notice that the call may be recorded and handled by an automated assistant covers both recording consent and AI disclosure. Utah already requires businesses to confirm they're using AI when a caller asks.
2. Default to the strictest rule. If you take calls from all-party states, treat every call as one.
3. Know where recordings go. Ask providers how long they keep audio and transcripts, who can access them, and whether call data trains their models.
4. Bring in counsel for regulated calls. Healthcare, financial, and payment calls add HIPAA, state privacy, and PCI DSS requirements.
