I understand.  Changing To/From by a proxy has long been a thorny 
issue, in the sense that on the one hand those fields are purely 
cosmetic in strict-3261 mode, but on the other hand, changing them 
breaks 2543 compatibility, and it's just not something a proxy is 
supposed to do.

I suppose that a very strict UA could also refuse to process replies 
which contain From/To header values that do not match the ones it 
sent, even if those values are not used for dialog or request 
association or anything related to maintenance of state per se.
