Hi Ovidiu,
Let me share some of the dark corners of openser :) (not known for most
of the people) :
$T_branch_idx counts the valid (outgoing) branches and not the branch
attempts.
If you have 2 branch attempts and first is discarded, the second will
take the index 1.

Hello,
I was playing wit append_branch and I run into this issue.
Here's a snippet of the code:
route[2] {
$var(uri) = $ru;
append_branch();
$ru = $var(uri) + ";transport=udp";
t_on_branch("2");
}
branch_route[2] {
xlog("L_INFO", "entering branch[$T_branch_idx] for $ru\n");
if ($T_branch_idx == 1) {
xlog("L_INFO", "dropping branch[$T_branch_idx]\n");
drop();
}
}
In the logs, I got:
entering branch[1] for sip:<user>@<IP>;transport=udp
dropping branch[1]
entering branch[1] for sip:<user>@<IP>
dropping branch[1]
ERROR:tm:t_forward_nonack: failure to add branches
Is this the expected result?
It seems that we do have two branches, since we enter twice in the
branch_route, but the $T_branch_idx doesn't seem to be updated. Or,
it is supposed to be updated?
Any hints would be appreciated.
BTW: this is with 1.3 code base.
Regards,
Ovidiu Sas
