Hello guys,
I'm having a strange problem with my Kamailio 1.5.3 when trying to register
an Audiocodes Gateway. I'm using authentication for REGISTER messages.
The GW sends a REGISTER without credentials, so I do a proxy_challenge. Then
the GW sends a REGISTER with credentials but the proxy_authorize is
returning -4.
I did an NGREP to check the messages and they don't seem malformed, can you
tell me if there is something on the functions that might be loosing the
Proxy-Authorization header?
This happens only with this GW, not if i register a softphone (XLITE).
Within route block:
...
if (is_method("REGISTER"))
{
route(11);
save("location");
exit();
}
...
Route(11):
route[11] {
# ----- AUTENTICACION DE UN MENSAJE -----
if (!proxy_authorize("", "subscriber"))
{
switch($retcode)
{
case -1:
xlog("L_INFO", "AUTH: Invalid username\n");
sl_send_reply("403", "Forbidden");
exit;
case -2:
xlog("L_INFO", "AUTH: Invalid password\n");
sl_send_reply("403", "Forbidden");
exit;
case -3:
xlog("L_INFO", "AUTH: Nonce ambiguo\n");
break;
case -4:
xlog("L_INFO", "AUTH: No credentials\n");
break;
#default:
#xlog("L_INFO", "AUTH: Unknown error\n");
#break;
}
#xlog("L_DBG", "AUTH: -Data- Auth Username = $au\n");
#xlog("L_DBG", "AUTH: -Data- Domain = $fd\n");
#xlog("L_DBG", "AUTH: -Data- From Username = $fU\n");
proxy_challenge("192.168.200.130","0");
exit;
};
xlog("L_INFO", "AUTH: Valid username and credentials\n");
consume_credentials();
}
