Hello,
for the question of this thread it is important to know the version of
kamailio used. In older versions, append_branch was called on purpose
upon changes in failure route, in latest one, changes to routing URIs
will be detected and a new branch is created by t_relay().
I do not know if latest lcr does internally append_branch(), but if it
does and you change afterwards r-uri, then you will get two branches.

This one I do not understand. Also I do not see the code where you
change $dU?
$dX - is the pseudo-variable for internal destination uri field (or
outbound proxy address) -- this will not be shown in the sip message at
all. Since user part of a SIP URI has no relevance in the IP routing,
$dU (which you may think it is the user part of dst uri) is not exported
as PV.
Cheers,
Daniel
Anyway, it seems that 2 branches are added: maybe one by lcr module
internally via next_gw and one manually? You can try to change $dU
before calling next_gw and omit the append_branch() call.

klaus
