Hi,
A
little strange text in 12.2, I think...
What
is the use of including a mid-session Record-Route header if you can't change
the route set? I am not saying one should be able to change the route set, but I
wonder what the Record-Route header shall be used for...
Also,
to my understanding the remote target URI is also part of the route set, ie the
route set is built also using the Contact header?

Further to that, the route-set in the dialog
never changes even if there is a record-route header in the response (UAS just
copies this from the request to the response) to a mid-dialog
request.
"Requests within a dialog MAY contain
Record-Route and Contact header
fields. However, these
requests do not cause the dialog's route set
to be modified,
although they may modify the remote target URI."

Record-Route and re-INVITE
Hi,
There has been discussions about if it is allowed to change the route
set during a session, but in general the re-INVITE is like any other
mid-session request, ie if you have a route set you include the Route
headers...

Hi,
When we send out re-INVITE do we need to include the
Route headers with it? Does the Record-route header in
the re-INVITE change/modify the route-set? When we respond to the
re-INVITE, do we need to include the Record-route header in the 2xx
messsage?
Thanks & Regards,
Meena
