Hello,
I am working on Kamailio 3.2.2. There is no traffic, only functional test done.
Based on the SIP Client used until now (Xlite), the INVITE is systematically authenticated by 407 as there is no Proxy-Authorization in the initial INVITE. Expected/normal behavior.
But when using an internal SIP client, the initial INVITE is generated with a Proxy-Authorization containing the nonce value used by the successful registration.
_In Authorization of Register (the answer is 200OK)_
Digest username="+33296488922@ims.v0.pftest.net", realm="sip:ims.v0.pftest.net", nonce="UDP43lAzpH7SjicT6+9/KDDloW4OTfTXoGWlZurBVut0JV604jox/QY+tVeA", uri="sip:ims.v0.pftest.net", response="4ed51b8e62cf769b19f8c4771e068ad3", cnonce="06440000000529330fe1", qop=auth, nc=00000011
_In Proxy-Authorization of Invite _
Digest username="+33296488922@ims.v0.pftest.net", realm="sip:ims.v0.pftest.net", nonce="UDP43lAzpH7SjicT6+9/KDDloW4OTfTXoGWlZurBVut0JV604jox/QY+tVeA", uri="sip:0157361149@ims.v0.pftest.net", response="b247052d6d5b37e0b6677c816390cb77", cnonce="06440000000529330fe1", qop=auth, nc=00000012
As the nonce expire is high (see nonce_expire), I don't understand why Kamailio requests the Authentication of the INVITE by 407.
_407 with Proxy-Authenticate_: Digest realm="ims.v0.pftest.net", nonce="UDP6pVAzpkWDF+jSlP3zzVYcuNPhY8NQBj62WIA=", qop="auth", stale=true
*Does it mean that the REGISTER and INVITE are using different Nonce value ? *
èInformation on my configuration file.
modparam("auth_db", "db_url", DBURLAUTH)
modparam("auth", "auth_checks_register", 6) # callid and From TAG
modparam("auth", "qop", "auth") # enable qop=auth
modparam("auth", "nonce_count", 1) # enable nonce_count support
modparam("auth", "nonce_expire", 21600) # Set nonce_expire to 6 hours
For register, I do
if (!www_authorize("$ru", "subscriber")) { if($? == -2 || $? == -3) { sl_send_reply("403","Forbidden auth ID"); exit; } else { www_challenge("$ru", "17"); exit; } }For invite, I do
if (!proxy_authorize("$fd", "subscriber")) { if($? == -2 || $? == -3) { sl_send_reply("403","Forbidden auth ID"); exit; } else {proxy_challenge("$fd", "17");
xlog("L_INFO","INVITE challenged by 407 to :$di:$dp \n");
exit; } }Followed by consume_credentials();
Thanks in advance for your support.
set debug=3 in your configuration file and watch the log messages. You should get some leads about why the authentication is not succeeding.
