Two-party consent
Two-party consent is a recording rule that requires every participant's permission before certain private or confidential conversations may lawfully be recorded.
The more precise term is often all-party consent, because a call may include more than two people. The label describes whose permission is needed; it does not mean every jurisdiction uses the same definition of consent, covers the same kinds of conversations, or provides the same exceptions. The applicable rule can depend on where each participant is located and where the recording occurs.
Two-party consent is commonly contrasted with one-party consent, under which one participant may be able to authorize a recording. That distinction is only a starting point. A call can cross state or national borders, involve a participant with a reasonable expectation of privacy, or fall under a separate sector-specific rule. Organizations should determine the governing requirements for their actual call routes rather than relying on a single state label.
How it affects an AI phone agent
If all-party permission is required, the agent needs a clear consent step before recording proceeds. The prompt should state that the call will be recorded, ask for an unambiguous response when affirmative consent is needed, and define a safe path for refusal or uncertainty. That path might continue without recording, transfer the call, or end it, depending on the organization's approved policy and technical setup.
The design must cover more than the ideal response. Callers may interrupt the disclosure, answer indirectly, remain silent, or add another person after the call begins. A transfer can also introduce a new participant. Testing these branches helps ensure the system does not treat background speech or ordinary conversation as agreement.
What the rule does not cover
Two-party consent is about recording; it is not blanket consent for the call itself, for marketing, or for later use of the collected data. It also does not replace a bot disclosure when one is required. Each permission or notice should be evaluated separately and presented clearly enough that the caller understands the relevant choice.
Because recording laws and their interpretation vary, this term should not be used as a complete compliance policy. Teams should document the jurisdictions, call types, artifacts, and exception handling in scope, then have qualified counsel review the workflow before launch.
