Indeed. As I understand the documentation, this uses the incoming branch
ID/Via added by the previous hop, correct?
Yes, and my test verifies it. Even when I call rtpengine_offer after
t_relay in branch route with via-branch value 1 (= first via header), I
still get the incoming via header branch id as the value of via-branch
option.
