I read his disclaimer as "I'm in a one-party consent state, but the person I'm talking to may or may not be - and I have no idea how admissible this would be as evidence but I'm pretty sure I'm not breaking the law."

So if your state is a one party consent state and you are one of the parties it doesn't matter what the rules in the other state are.
Now what could get interesting is if you are in a one party state and you are calling on a cell phone and you hit a tower in another state. So then you claim that you are in State A and if they were to put in the effort to check or cell records they saw you hit the tower in State B then I would guess you would have to offer further proof of actually making the call in State A other than your statement that was the case. (As opposed to a land line where it's clear where you are located).

If it is where the recording is taking place, a VoIP provider could do all the recording on servers in a state friendly to the recording, regardless of where the participants in the call are.
[1] For that matter what if you conference in a friend and the friend is the one that did the recording.
I have no idea what happens, though, when one party is on a two-party state and the other is in a one-party state.
