Exactly - thanks - I'll enter a bug against that sentence in 12.2

3261 section 6 "Target Refresh Request: A target refresh request sent

3261 12.2 "Target refresh requests only update the dialog's remote
target URI,
and not the route set formed from the Record-Route."
So I guess this is said in context of not affecting the route set, but
still Target refresh requests may update additional characteristics of
the dialog (secure, seq num) right?
From section 14 it is implied that Target Refresh Requests are not
supposed to impact the media characteristics of the session - is that
right?

Subject: Re: [Sip-implementors] Target refresh requests
Just to be sure there is no confusion:
Target refresh requests are any request that updates the Remote URI.
Could you point to where
you saw "only the Remote URI"? That's not right and I'll put a bug
against whatever text led you to
that.
The currently defined target refresh requests are INVITE, UPDATE,
SUBSCRIBE, NOTIFY, and REFER.

One example is when a UA in a call wants to mutate into a conference
mixer. So maybe it changes from
Contact: <sip:[EMAIL PROTECTED]>
to
Contact: <sip:[EMAIL PROTECTED]>;isfocus
Another case is when you have some sort of cluster and want to hand
off the call from one cluster member to another for load balancing or
fault recovery.

The SIP RFC (3261) defines Target refresh requests as requests that
are sent within a dialog and update only the Remote URI. Does anyone
have an good use case example for such a request?
