Michael,

My reading of RFC3325 indicates that
P-Asserted-Identity/P-Preferred-Identity is only added on a method (e.g.
INVITE) to indicate the identity of the caller.  I do not see where it
would be applied to a 18x provisional response to indicate the identity
of the called party.  Am I missing something?
