This is not accurate. California makes it illegal to record "confidential" communications, which is sometimes called "two party consent," but that shouldn't be interpreted to mean that affirmative consent is required. Notice that the call may be recorded defeats any presumption of confidentiality and makes it permissible for any party to record the conversation. (I am a lawyer and have litigated these cases. But I'm not your lawyer and this is not legal advice.)
I'm not seeing the claims that you are refuting about California in the quoted text. My point was just to illustrate that most states are not two party consent.
