Hello,
I am trying to set simple no-answer forward scenario: Alice calls Bob and
after timeout 5s forward to Carol (and additionally Carol timeout forward to
Dave).
I am using Kamailio 3.2.2 default config. There is part of routing logic for
no-answer forwarding:
route[RELAY] {
if(is_method("INVITE")) {
t_set_fr(5000);
t_on_branch("BRANCH_ONE");
t_on_reply("REPLY_ONE");
t_on_failure("FAIL_ONE");
}
if(!t_relay()) {
sl_reply_error();
}
}
branch_route[BRANCH_ONE] {
$avp(divert) = $null;
if($rU == "bob") {
$avp(divert) = "carol";
}
# second problem
if($rU == "carol") {
$avp(divert) = "dave";
}
}
failure_route[FAIL_ONE] {
if($avp(divert) != $null) {
add_diversion("no-answer");
$rU = $avp(divert);
route(LOOKUP);
route(RELAY);
}
}
First problem I encountered is that I can't check $rU in failure_route (it is
always set to original Request-URI - bob). Is this normal behavior or am I
missing something? Because of that I have to set divert destination in branch
route.
Second problem is when Carol's no-answer forward to Dave happens. Then
add_diversion adds invalid diversion header because it uses Request-URI which
is still set to bob.
Kind Regards,
Jan
