If you're not a party to the conversation, you can record a conversation or phone call provided one party consents to it after having full knowledge and notice that the conversation will be recorded. Under Federal law, 18 U.S.C. § 2511(2)(d) requires only that one party give consent.
Also question is, can you record a phone call without the other person knowing?
"Federal law permits recording telephone calls and in-person conversations with the consent of at least one of the parties. This is called a "one-party consent" law. Under a one-party consent law, you can record a phone call or conversation so long as you are a party to the conversation."
Keeping this in view, are call recording apps legal?
You only need to download an app. In fact, some phones come with an in-built call recording option, allowing users to choose to record all calls by default or record a specific call. There is no law which makes recording a call by an individual on their device illegal.
As a general rule, it is illegal for businesses to record phone conversations in Australia without obtaining consent from the other person. For example, in Queensland, you can record a phone conversation with the consent of only one party — the other person doesn't even have to know the phone call is being recorded.
