Hi
Im trying to modify example for Asterisk/Kamailio integration that miconda
did, and trying to handle Forwarded register to Asterisk in an
authenticated way instead removing secret in asterisk.
I have made this changes
route[REGFWD] {
if(!is_method("REGISTER"))
{
return;
}
$var(rip) = $var(astip);
$uac_req(method)="REGISTER";
$uac_req(ruri)="sip:" + $var(rip) + ":" + $var(astport);
$uac_req(furi)="sip:" + $(au{s.substr,8,0}) + "@" +
$var(rip);
$uac_req(turi)="sip:" + $(au{s.substr,8,0}) + "@" +
$var(rip);
$uac_req(hdrs)="Contact: <sip:" + $au + "@"
+ $sel(cfg_get.kamailio.bindip)
+ ":" + $sel(cfg_get.kamailio.bindport) +
">\r\n";
if($sel(contact.expires) != $null)
$uac_req(hdrs)= $uac_req(hdrs) + "Expires: " +
$sel(contact.expires) + "\r\n";
else
$uac_req(hdrs)= $uac_req(hdrs) + "Expires: " +
$hdr(Expires) + "\r\n";
xlog("Dentro de REGFWD");
t_on_failure("REG_AST");
uac_req_send();
}
failure_route[REG_AST] {
if (t_is_canceled()) {
exit;
}
xlog("Dentro de REG AST");
if(t_check_status("401|407")) {
xlog("Dentro de 401");
$avp(auser) = "test";
$avp(apass) = "test";
uac_auth();
t_relay();
exit;
}
}
What i see on traces:

But Kamailio is not sending authentication .
Any idea what could be wrong? Or any tip to do what i try.
The idea is that a sip endpoint register with authentication on kamailio
and it sends register with authentication to asterisk.
Thanks in advance
