Re: [OpenSIPS-Users] Generate CANCEL on 180
Hello,
In 3.1, create_dialog [1] supports passing it the 'E' flag which will
lead to the call termination if a dialog race condition occurs.
The dialog will be ended after race_condition_timeout [2] seconds.
Some of the most frequent race conditions are documented in RFC 5407
[3], and the dialog module currently supports terminating the call in
case races 3.1.2 and 3.1.3 from the RFC occur.

Firstly, I'm new to OpenSIPS so treat my comments accordingly.
But, can you do something in an onreply route?
eg, in a test setup I have, when I get an INVITE I do this:
create_dialog("pPB");
t_on_reply("doodle");
(I can't remember whether the dialog is needed for this)
and then I have this:
onreply_route[doodle] {
# expect $T_reply_code to likely first be 100
# then 180 or 183 for a progressing call
# 200 when call is answered
# or failure code (eg 4xx) or whatever
if (t_check_status("^1[0-9][0-9]$")) {
switch ($T_reply_code) {
case 180: $acc_extra(t_ringing) = $Ts; break;
case 183: $acc_extra(t_progress) = $Ts; break;
}
} else if (t_check_status("^2[0-9][0-9]$")) {
$acc_extra(t_answer) = $Ts;
} else {
xlog("Something else\n");
}
}
so when a 180 is received, it calls the above route function. Could you send a
CANCEL from there?
Cheers,
Kingsley.

Re: [OpenSIPS-Users] Generate CANCEL on 180
So there is a race between the CANCEL you send and the incoming 200 OK,
right ? And does the carrier even reply to that CANCEL? the RFC3261 says
it is a must to provide a reply to any incoming request.

Firstly, I'm new to OpenSIPS so treat my comments accordingly.
But, can you do something in an onreply route?
eg, in a test setup I have, when I get an INVITE I do this:
create_dialog("pPB");
t_on_reply("doodle");
(I can't remember whether the dialog is needed for this)
and then I have this:
onreply_route[doodle] {
# expect $T_reply_code to likely first be 100
# then 180 or 183 for a progressing call
# 200 when call is answered
# or failure code (eg 4xx) or whatever
if (t_check_status("^1[0-9][0-9]$")) {
switch ($T_reply_code) {
case 180: $acc_extra(t_ringing) = $Ts; break;
case 183: $acc_extra(t_progress) = $Ts; break;
}
} else if (t_check_status("^2[0-9][0-9]$")) {
$acc_extra(t_answer) = $Ts;
} else {
xlog("Something else\n");
}
}
so when a 180 is received, it calls the above route function. Could you send a
CANCEL from there?
Cheers,
Kingsley.

Re: [OpenSIPS-Users] Generate CANCEL on 180
Certain providers do this all the time : they bill faulty numbers
So they give 180 followed by instant 200 and then they play : "the number
that you tried to reach ".
Actually, Antonis, you should try a few of those numbers manually, I bet
you that they are all faulty.

Once you receive 200 it is too late to CANCEL. You will need to ACK the 200
and then BYE the call.

Re: [OpenSIPS-Users] Generate CANCEL on 180
I did the following
if (t_check_status("180"))
{
t_cancel_branch();
drop;
}
But there is an issue.
When 180 is followed by 200 instantly, the CANCEL is not working as expected.
When I add a delay on Answer ie 1sec then CANCEL works.
Any suggestion?

switch ($T_reply_code) {
case 180: $acc_extra(t_ringing) = $Ts; break;
case 183: $acc_extra(t_progress) = $Ts; break;
}
} else if (t_check_status("^2[0-9][0-9]$")) {
$acc_extra(t_answer) = $Ts;
} else {
xlog("Something else\n");
}
}
so when a 180 is received, it calls the above route function. Could you send a
CANCEL from there?
Cheers,
Kingsley.

Re: [OpenSIPS-Users] Generate CANCEL on 180
Firstly, I'm new to OpenSIPS so treat my comments accordingly.
But, can you do something in an onreply route?
eg, in a test setup I have, when I get an INVITE I do this:
create_dialog("pPB");
t_on_reply("doodle");
(I can't remember whether the dialog is needed for this)
and then I have this:
onreply_route[doodle] {
# expect $T_reply_code to likely first be 100
# then 180 or 183 for a progressing call
# 200 when call is answered
# or failure code (eg 4xx) or whatever
if (t_check_status("^1[0-9][0-9]$")) {
switch ($T_reply_code) {
case 180: $acc_extra(t_ringing) = $Ts; break;
case 183: $acc_extra(t_progress) = $Ts; break;
}
} else if (t_check_status("^2[0-9][0-9]$")) {
$acc_extra(t_answer) = $Ts;
} else {
xlog("Something else\n");
}
}
so when a 180 is received, it calls the above route function. Could you
send a CANCEL from there?
Cheers,
Kingsley.
