What about terminating early dialogs using the MI interface? Assuming
that a provisional response carried a Contact header and no final
response was sent yet, it seems to me that terminating such an early
dialog would only be possible if the dialog module actually stored the
header. This is beyond purely informational purposes.
On the other hand, I don't think terminating early dialogs isn't
supported by the current implementation anyway. Changing that would just
mean another feature, making it less critical.

The conclusion is easy:
The 200 must contain Record-Route and Contact so the Dialog module
shuld just care about such fields in the 2XX response.
Anyhow, for information purposes, it could extract these fields from
provisional responses and set the dialog_out entries according. Alright. Let me know when you found the time to
dig it out.
This is the thread. I must re-read it:
https://lists.cs.columbia.edu/pipermail/sip-implementors/2008-August/020028… Other issue: dialog flags.
The proposal just allows setting a dflag during onreply_route. This
makes a lot of sense as there is no dialog yet in route, branch_route
and failure_route. So setdflag() function just could be inoked in
onreply_route. Is it ok?
Dialogs are already established in spiraling cases, however. Might it
prove useful if dflag manipulation worked the instant a spiral is
happening (which may be in route or branch_route)?
