IANAL. I asked a lawyer about this and they said that recording a phone call from a one-party consent state to someone in any other state is typically legal without consent, as long as the the person recording is on the call.

Personally, I think it's courteous to at least inform that it's being recorded, legality aside.

> typically the law applies to the state where the recording is made.
