Hi Antonio,
OpenSIPS allows you to do only one TO / FROM change per branch.
Changes you do in main Route are inherited by all future branches
(including default branch 0). Changes you do in branch route will
affect only that branch

=> you do 2 changes for the branch (global change and per-branch change)

use also branch route for changing the first branch. and only branch
route (if you want to do changes per branch:
route {
t_on_failure("1");
t_on_branch("1");
t_relay();
}
branch_route[1] {
uac_replace_from("", "sip:$avp(s:from)@$fd");
uac_replace_to("", "sip:$avp(s:to)@$td");
}
failure_route[1] {
t_on_branch("1");
if(!next_routing()) {
t_reply("$err.rcode", "$err.rreason");
exit;
}
t_relay();
}
