The MAR portion of registration is either not happening or failing
causing scscf to die. Using Kamailio 4.0 with the ims_auth module.
We're trying to determine what
the REGISTER block should look like and what ims_auth parameters are
necessary for a successful MAR challenge with auth vector delivery. We
currently only get the UAR by ICSCF then the SAR by SCSCF.
Module parameters:
# -- ims_auth params --
modparam("ims_auth", "name", URI)
modparam("ims_auth", "registration_default_algorithm", REG_AUTH_DEFAULT_ALG)
modparam("ims_auth","ignore_failed_auth",0)
#!ifdef CXDX_FORCED_PEER
modparam("ims_auth", "cxdx_forced_peer", CXDX_FORCED_PEER)
#!endif
modparam("ims_auth", "cxdx_dest_realm", NETWORKNAME)
modparam("ims_auth", "av_request_at_once", 1)
modparam("ims_auth", "registration_qop", "auth")
route[REGISTER] {
xlog("L_ERR", "Enter register block");
t_newtran();
ims_www_authenticate(NETWORKNAME);
#check to see if user is authenticated - ie sip header has auth
information - (already challenged)
if ($avp(maa_return_code) == 1) {
# user has not been authenticated. Lets send a challenge
via 401 Unauthorized
ims_www_challenge("$td");
exit;
} else {
# We need to check if this user is registered or not
if (!impu_registered("location")) {
save("location");
if ($avp(saa_return_code) == 1) {
isc_match_filter_reg("0","location");
exit;
}
} else {
save("location");
if($avp(saa_return_code) == 1) {
isc_match_filter_reg("1","location");
exit;
}
}
}
}
