Not to mention the expansive myriad of things that can "answer" the call 
these days, like sundry voicemail systems, that do not constitute an 
"answer" in the sense desired by the transferring party.

On the other hand, if you make the ring timeout too short, that breaks 
functionality such as call forwarding to a cell phone on the recipient side.

It seems to me that keeping blind transfer truly "blind" is the only 
viable strategy in the contemporary device, service and feature milieu.
