Hello Federico,
You are right. The first line comes from the other core dump (which is
related to normal sig handling on crash).
In my scenario, I have only 2 SIP client: one caller and one callee
I am starting the callee after call is initiated then kill the callee, then
relaunch the callee.
Each time I expect the call to be presented again.
It seems that the issue arrives when I wait for timeout after this scenario.
Its confirmed by the log where the issue arrives each time in MANAGE_FAILURE
failure_route[MANAGE_FAILURE] {
route(NATMANAGE);
if (t_is_canceled()) {
exit;
}
....
}
