Hi fellow kamailio users,<br>
<br>
I'm playing actually with t_on_branch_failure, in a simultaneous
forking scenario ( lookup("location") returns multiple contacts ).<br>
<br>
Any idea on how to get those "on_branch_failure" working ? <br>
<br>
Thanks in Advance !<br>
<br>
* Test by putting failure_exec_mode:<br>
- at 1 => no branch failure being called, never.<br>
- at 0 => t_relay does not fail if a single branch answers the
transaction, even if all other branches are failing.<br>
<br>
* Test by moving the t_on_branch_failure("manage_branch_failure");
line before or after the lookup("location") or on a _on_branch route
to set it per branch.<br>
- The on_route branch are executed, but never the failure one.<br>
- tried also with failure_exec_mode = 0 or 1.<br>
<br>
* Using set_forward_no_connect, I can see in the logs a "Sending to
branch X failed" but no failure route being executed. Without it,
nothing in the logs indicating that the branch has timeout.<br>
<br>
* Config extract:<br>
<br>
