In Illinois, we have a two-party consent law on phone calls, requiring both parties to agree to being recorded. (Or, it seems, simply be told "This call may be recorded for ___ purposes", and you simply continue the phone call.
In Wisconsin, the law is one party. If I drive up to the Wisconsin border with my Illinois Phone number, what takes precedence for that phone call? The registered number's area (my Illinois area code), or the physical location I'm standing when making / receiving the call?
Also, when you state that the call is recorded for ___ purposes, does that have any bearing on the actual use (e.g. they state it is for quality assurance, but instead they use it for marketing, legal, etc)
