Hello everyone,
I use from uac_req_send()function from UAC module for generation of REGISTER request in
onreply_route , I assign new values for all headers of my packet before sending my new
generated request but I can't assign value for CSeq header. It doesn't define and
when I try to assign it, I got an error .
I analysed packet flow through Wireshark and recognized always value of CSeq header for my
new register request is 10.
I want to assign new value for my REGISTER packet in configuration file..

Can you give more details about the expected behavior and your configuration? If you need
more help in debugging it, it would be good to discuss it first on the sr-users e-mail
list

Hello,
I wanted to generate "Authorized REGISTER" after receiving "401
unauthorized" response from upstream server by my kamailio core . I could
assign new values for many headers like this($uac_req(ruri)="sip:" +
$var(uri); ) but it was impossible to assign new value for Common Sequence
header .it wasn't defined in source codes .
With your permission I solved my problem with modification in (uac.s and
uac_send.c source code) then I recompiled kamailio core again. after
changes I can assign new value to CSeq header ( $uac_req(cseq)= $(cs{s.int})
+ 1;) and my problem solved.
with this solution upstream server accepts my response because CSeq is more
than "401 unauthorized " response from its side.
If you would like I can send my modifications and configuration file .
thanks in advance

Have you tried setting `track_cseq_updates` from dialog module?

@maryamb99 - have you set the username and password before uac_req_send() -- see the
attributes at:
* https://www.kamailio.org/wiki/cookbooks/devel/pseudovariables#uac_req_key
The CSeq is incremented automatically when getting the 401/407.

I need something like $uac_req(method) which let me to assign new value to CSeq header of
my new packet but it isn't defined in structure of uac module and I added this part in
source of uac and tm modules
according to my observations , always CSeq number is 10 in type of my requirements and my
definitions , not incremental after receiving 401

I checked the code and it should be incremented. Can you paste here the part of the config
where you set $uac_req() attributes and do uac_req_send()?

Did a small check and the CSeq is incremented, the config snippet:
```
request_route {
if(is_method("OPTIONS")) {
sl_send_reply("200", "ok");
$uac_req(method)="INFO";
$uac_req(ruri)="sip:test@" + $Ri;
$uac_req(furi)="sip:test@" + $Ri;
$uac_req(turi)="sip:test@" + $Ri;
$uac_req(auser)="test";
$uac_req(apasswd)="test123";
uac_req_send();
exit;
}
if(is_method("INFO")) {
if (!pv_auth_check("$fd", "test123", "0", "1"))
{
auth_challenge("$fd", "0");
exit;
}
}
sl_send_reply("200", "ok");
}
```
And the sip trace for info request:

If you want to do something else, then likely you want a new feature. Closing this one.
