I intentionally overlooked it, as I don't feel like getting into a meta-discussion about the varying laws and the ethics of recording calls, depending on the level of informed consent, etc.
I'll just point out that, when recording an inbound call, both parties hear Kiki announce the fact that the call is being recorded, so there is no way to surreptitiously record a call without both parties being informed. This isn't the case with outbound calls.
