Re: [OpenSIPS-Users] Generate CANCEL on 180

2021-04-20 Thread Calvin Ellison 
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

2021-04-20 Thread Antonis Psaras 
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?

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] dialplan module - dpid - could it be a string?

2021-04-20 Thread Ben Newlin 
This sounds like it might be a good feature request [1] and I agree it sounds 
nice. I can’t offer any assistance in that direction at this time, but I wanted 
to say that we use M4 in our config scripts to allow us to define string 
constants like this and make the script more readable, among other reasons. 
Could be a good short-term workaround. We specifically use it to define 
string-based dialplan IDs for use in the script, just like this.

I love the dialplan module and how the rules can be reloaded from a DB.

However, is there any reason why the dpid can't be a string instead of
an integer? (ie the value that's stored in the dialplan.dpid field).

I think it would be handy to be able to apply names to dialplan
rulesets as it would be more intuitive. If dpid could be a string, then
I could for example create a ruleset that I could refer to as
"uk_local_to_e164" instead of "7".

Could this be a thing?

[OpenSIPS-Users] dialplan module - ensuring a substring exists in URI

2021-04-20 Thread Kingsley Tart 
Hi,

I want a DP ruleset to ensure that ";user=phone" is in the SIP URI, ie
if it is not there, add it, but if it is already there, do nothing.

I've managed to do this with two lines, but is there a more efficient
way?

This is what I have in the dialplan table in this ruleset?

++--+-+-+---+---+
| pr | match_op | match_exp   | match_flags | subst_exp | repl_exp  |
++--+-+-+---+---+
|  1 |1 | ;user=phone |   1 | (.+)  | \1|
|  2 |1 | .   |   1 | (.+)  | \1;user=phone |
++--+-+-+---+---+

Kingsley.

2021-04-20 Thread Kingsley Tart 
Firstly, I'm new to OpenSIPS so treat my comments accordingly.

eg, in a test setup I have, when I get an INVITE I do this:

and then I have this:

}
} else if (t_check_status("^2[0-9][0-9]$")) {

}

so when a 180 is received, it calls the above route function. Could you
send a CANCEL from there?

Dear all

I am trying to create a service which will generate missed calls. In order to 
be more accurate, I want to CANCEL the request when 180 is received.

The scenario is the following

Asterisk Invite -> OpenSIPs -> Carrier

Carrier 183 -> OpenSIPs -> Asterisk

Carrier 180 -> OpenSIPs

OpenSIPs Cancel -> Carrier

 

Is that possible to be done from script without external app?

[OpenSIPS-Users] Removing INVITE Contact from Reply (2.1.5)

2021-04-20 Thread mwb via Users 
Hello,I posed a questions a few months ago and received some helpful advice 
from a user here but I'm having an issue implementing it properly.
We have a redirect server using OpenSIPS 2.1.5 that does LNP dipping with a 
little bit of routing as well. 
There are two scenarios:
1. There is No RN/NPDI in the RURI (so the redirect server sends a LNP request 
to an external LNP server
2. The INVITE has RN/NPDI in the RURI so no LNP dip is dispatched.
In the second scenario we do a few operations and generate URIs to embed in a 
302 reply using the send_reply function in a . The issue we are running into is 
that it appears the $ds variable is being populated with the INVITE Request URI 
(RN and/or NPDI) info and it is being sent as the "top" Contact header in the 
302 response. 
I have tried a few different things, including "remove_branch(0)" but they 
don't seem to be able to clobber the value in the $ds variable. It also seems 
impossible to use $ds as an LVALUE to try and overwrite it (this is consistent 
with the documentation which says it is not r/w).
Is there a way to:
1. Clobber the $ds variable?2. Preclude the $ds variable from being inserted as 
a Contact header in the reply?3. Keep the $ds variable from being populated 
when the initial INVITE is received.
Thanks!___
