Hi,
  "Replaces"  header field is to replace an existing dialog..

   Assume that session is established between A and B then  A want to
change the dialog ..then A has to send reINVITE request with "replaces "
header field ..then if B accepts that reinvite then..for exisiting
dialog it has to send "bye" message.
 I guess.. to change the display name it won't work..

In addition to Jerry's two suggestions, another popular technique is to
send an INVITE with Replaces header instead of the reINVITE.  You can
update all manner of indications in the new initial INVITE, which most
phones will use to update their display.

See RFC 3891 for details of the replaces header.

Michael
