[OpenSER-Users] append_branch and $T_branch_idx behavior

[Ovidiu Sas]

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.
