Hi again. <br>
Seems to be, $hdr(Proxy-Authenticate) is NULL at 401
response.<br>
<br>
failure_route[1] {<br>
...<br>
if ( t_check_status("40[17]") ) {<br>
...<br>
xlog("L_INFO", "Asterisk flavour $hdr(<big><big><font
size="-2"><big><big>WWW-Authenticate</big></big></font></big></big>),
Proxy flavour $hdr(Proxy-Authenticate)");<br>
}<br>
}<br>
<br>
becomes <br>
<br>
/usr/sbin/opensips[18983]: Asterisk flavour
<null>, Proxy flavour <null><br>
<br>
It's logic, cause in failure_route we work with initial
INVITE, but not 401 reply. Cause, if we working with
reply directly, we can't apply uac_auth function to it.<br>

<pre wrap="">Hi,
Many thanks on your answer, will wait for a new feature and look at $hdr var more close.
Anyway, I have a little trouble with CSeq change (means it is need to do accurate), but for now it’s a solution.
Many thanks again.

<pre wrap="">Hi,
1) on changing cseq as a simple text - this is not wise as you break the sequence of cseq number in the dialog; we are working on a feature to allow you do that in sip-wise way.
2) about realm, the proxy/www -Authenticate header (in the 401/407 reply) has the realm parameter; you can grab it by transformations; on $hdr(Proxy-Authenticate) apply a regexp transformation (see <a moz-do-not-send="true" class="moz-txt-link-freetext" href="http://www.opensips.org/Documentation/Script-Tran-1-11#toc72">http://www.opensips.org/Documentation/Script-Tran-1-11#toc72</a>) to get the realm param from there.

Is there any luck to get Asterisk auth (without touching Asterisk)

<pre wrap="">Hi!
I'm trying to get OpenSIPS 1.11 act as registrar proxy. Means it's not
only register on external servers, but take care of INVITE's and so.
I've configured modules as:
loadmodule "uac_auth.so"
loadmodule "uac.so"
loadmodule "uac_registrant.so"
modparam("uac","restore_mode","auto")
modparam("uac_auth","auth_realm_avp","$avp(uac_realm)")
modparam("uac_auth","auth_username_avp","$avp(uac_username)")
modparam("uac_auth","auth_password_avp","$avp(uac_password)")
modparam("uac_registrant", "timer_interval", 120)
modparam("uac_registrant", "hash_size", 2)
modparam("uac_registrant", "db_url",
"mysql://opensips:opensips@localhost/opensips")
....
failure_route[1] {
......
# have we already tried to authenticate?
if (isflagset(8)) {
xlog("L_INFO", "FAILUREROUTE_STATUS40X_SETFLAG8:
[F=$fu R=$ru D=$du M=$rm IP=($si:$sp $Ri:$Rp) ID=$ci]");
t_reply("503","Authentication failed");
exit;
}
if (is_method("INVITE")) {
# mark that auth was performed
setflag(8);
# trigger again the failure route
t_on_failure("1");
# repeat the request with auth response this time
$avp(uac_realm) = $td;
$avp(uac_username) = $fU;
avp_db_query("SELECT password FROM registrant
WHERE (registrar = 'sip:$avp(uac_realm)') AND ( username =
'$avp(uac_username)')","$avp(uac_password)");
xlog("L_INFO",
"FAILUREROUTE_STATUS40X_UACAUTHINVITE_DEBUG_VARIABLES: AVP_UAC_REALM:
$avp(uac_realm) AVP_UAC_USERNAME: $avp(uac_username) AVP_UAC_PASSWORD
:$avp(uac_password)");
uac_auth();
t_relay();
}
}
.....
}
I see correct vars in debug message, but uac_auth() not to append branch
to reply INVITE.
For example, I have such string
AVP_UAC_REALM: some-dns.example.net.ua AVP_UAC_USERNAME: 2225678
AVP_UAC_PASSWORD :SuperStrongPassword
What is wrong in this config/AVP's?
