I am perfectly willing to admit that I might not be imagining how things
might work.
Perhaps this depends very heavily on exactly what is retargeting and
what is not. If I call the Dr and get the answering service is that
retargeting? If I call the boss and get the secretary is that
retargeting? I I call you on your land line and get forwarded to your
mobile line is that retargeting? If I call a help line and get
forwarded to a call center worker is that retargeting?
In most of these cases, even if my UA has a UI to ask me if I want to
continue I will most likely just consider than annoying and reconfigure
it to automatically accept all of these retargetings.
I can see the value of being able to specify that I want to speak to a
certain person and no other, but I think I wojuld only want to use it on
rare occasions.
BTW, when it does matter to me I would prefer to restrict who actually
answers the phone, rather than just which phone rings. But I don't see
much likelihood of that any time soon.
I would be *thrilled* to just have called party identity on a regular basis.
