Hi,
Since these are B2BUAs, there are *three* different
early dialogs here:
- UAC:B2BUA1
- B2BUA1:B2BUA2

All the rules regarding route sets, etc. apply
separately to each.
I agree. However, I just wanted to mention that the 3gpp specs app

I agree. However, I just wanted to mention that the 3gpp specs appear to
be requiring B2BUA App

The B2BUA needs to be smart enough to know to not relay the PRACK even

Hi Gagan,
UAC constructs dialog-set when early dialog is created(on first prov rsp)
and this is maintained for rest of dialog .
Which means on getting first prov response ,route-set is filled.And not
updated on getting further prov responses.
Later when 200ok comes,route-set can be updated again
Hello
Suppose UAC receives multiple provisional responses before confirmation of
the dialog (2xx), and each provisional response has a different set of
Record-Route headers.
(Each provisional response is within the same early dialog. i.e. same
From-tag and To-tag.)
In this scenario:
1. Should UAC
