Hello,
like Joel said, the reveiced filed in location record is set only for
NATed contacts and in ipv6 likely it is not the case.
What you should do is like:
$uac_req(ruri) = $(ulc (existingContact=>addr)[0]);
if($(ulc(existingContact=>received)[0]) != $null) {
$uac_req(duri) = $(ulc(existingContact=>received)[0]);
}
Cheers,
Daniel

Hi, thanks for your response. I appreciate the help, I
really
appreciate it.
My problem is that I have to send a MESSAGE to an application to show
the user a message.
Like that:
*$ var (address) = $ (ulc (existingContact => received) [0]);
$ var (ruri) = $ (var (address) {s.substr, 4,0});
# Submit a SIP request stating the problem and its reason in the body
$ uac_req (method) = "MESSAGE";
$ uac_req (ruri) = "sip:" + $ au + "@" + $ var (ruri);
$ uac_req (furi) = "sip: kamailio @ sip_domain";
$ uac_req (turi) = $ fu;
$ uac_req (hdrs) = "Max-Forwards: 70 \ r \ nEvent: reg \ r \
nContent-Type: text / plain \ r \ nAccept-Contact: *; +
g.ext.app.registration \ r \ n" ;
$ uac_req (body) = "Already registered with another device ID";
uac_req_send ();*
For the previous user, I mean. The first record, not the second. How
can I get the first source IP address to replace $ var (address) = $
(ulc (existingContact => received) [0]); and send him the message? If
I use save (); module, I will have the same problem, because I will
not be able to find the previous IP source.
Thank you so much.
Kind regards.

Not exactly an answer to your specific question, but it might help
solve your problem in a different way...
If you using the registrar module with save()... you might be able
to take advantage in some way of the flags 0x04:
https://kamailio.org/docs/modules/5.3.x/modules/registrar.html#registrar.f.…
/"0x04 - store and maintain one contact per AoR. If there are
other contact addresses for AoR not matching current registration,
remove them. This mode ensures one contact per AoR (user)."

Regarding "received", I would think that you have it on IPV4
because the UA is probably behind NAT, and you are adding it in
config script, with IPv6, there is no NAT, and --most likely-- you
are not adding it, thus it's not saved to the database. Check if
you are using fix_nated_register() somewhere in your config file..
For IPv6 it might be easier if you just pull the IP from the
Contact info.
Sorry if this isn't very helpful, I'm guessing a little based on
the info you provided :)
Cheers,
Joel.

Hi;
I'm using the received parameter to send a MESSAGE to
unregsiter the first user that is registered to register the
second one.
Using:
*modparam("usrloc", "received_column"*
*modparam("registrar|nathelper", "received_avp",
*
*
*
and when I do a:
select received from location;
as you can see is null.
+----------+
| received |
+----------+
| NULL |
+----------+
In IPV4 is working fine, but in IPV6 is not. Can you tell me
how can I get this value?
Im going crazy with that.
reg_fetch_contacts("location", "$fu",
"existingContact");
if( $(ulc(existingContact=>user_agent)[0]) =~
"SPI/v"){
$var(oldDeviceId) =
$(ulc(existingContact=>callid)[0]{s.substr,9,0});
$var(newDeviceId) =
$(hdr(Call-ID){s.substr,9,0});
if($var(oldDeviceId) !=
$var(newDeviceId) ){
xlog("L_INFO","New device id
is different:warn previous user another user overide him");
$var(address) =
$(ulc(existingContact=>*received*)[0]);
$var(ruri) =
$(var(address){s.substr,4,0});
#Send a SIP Request signalling
the problem and its reason on the body
$uac_req(method)="MESSAGE";
$uac_req(ruri) = "sip:"+ $au +
"@" + $var(ruri);
$uac_req(furi) =
"sip:kamailio@sip_domain";
$uac_req(turi) = $fu;
$uac_req(hdrs)="Max-Forwards:
70\r\nEvent: reg\r\nContent-Type:
text/plain\r\nAccept-Contact:*;+g.ext.app.registration\r\n";
$uac_req(body)="Already
registered with another device id";
uac_req_send();
drop;
}
}
Thank you.
