By the way, I believe that the way I use the words, this is a  
"reroute" and not a "retarget". In the freephone case, I would still  
expect the destination to have an awareness that it is the target of  
freephone calls and have credentials for the freephone number such  
that it could appropriately authenticate its responses if we had a  
means to do so.

My definition is that a "retarget" changes the expected identity of  
the expected responder, introducing the possibility of an  
"unanticipated respondent" scenario.

This is, AFAIK, very different from the 4244 terminology, which I've  
always held to be not particularly useful.
