> In Oregon it is legal to record telephone conversations with the consent of at least one party, but recording in-person conversations requires the consent of all parties except for in certain circumstances, such as when all parties reasonably should have known they were being recorded. Illegal recording is a misdemeanor that can also give rise to civil damages.
