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 in dialog-set. Can you please explain scenario where provisional responses in same dialog coming via different route ?
