Consent should be in writing or should be given on the recording, or a verbal warning that the conversation is being taped should be included in the recording.
Anyone who records a telephone conversation without the consent of all the parties is subject to liability for civil damages, as well as litigation costs and attorney fees. In addition, it is a felony punishable by imprisonment for one to five years for anyone who is not a party to a conversation to mechanically overhear or record that conversation, including telephonic and cellular or wireless communications and face-to-face discussions, without the consent of at least one party.
