The phone analogy isn't really a good one. Why?
By cosmic phone, I guess most people would picture some sort of signal that was send by an alien civilisation. It's a one way signal. Picking up this
signal and "listen" to it, isn't answering the phone.
Because in terms of a real phone you dail a number and you hear the beeping sound when you're calling somebody. And when the other person picks up the
phone, the person calling knows that somebody picked up the phone. .
In the case of picking up an signal from an alien civilisation, that civilisation will not know if someone has picked up the signal.
They will only know when that other civilisation calls back.
So imho the correct analogy would be: "if the cosmic phone rings, don't call back"
