The short answer is “yes.”
Recording phone calls between two individuals or between a company representative and an individual can be covered by S18 U.S.C. 2511 (2)(d), which is known as the “one-party consent” law.
This law requires that at least one of the participants in the conversation be aware that the call is being recorded, which is an easy requirement to meet if you are recording your own conversations.
