[SR-Users] uacreg get error on 2nd 401: error uac_reg_tm_callback(): authentication failed

Hello, I try to register on provider`s pbx version: kamailio 5.7.0-dev0 (x86_64/linux) modparam("uac", "reg_db_url", "mysql://kamailio:123@localhost/kamailio") modparam("uac", "reg_contact_addr", "1.1.1.1:5060") modparam("uac", "reg_retry_interval", 120); # for failed registrations modparam("uac", "reg_keep_callid", 1) modparam("uac","restore_mode","auto") uacreg table: +----+---------+------------+-----------+----------------+-----------------+-------+----------------+------------------+----------+---------------------+---------+-------+-----------+--------------+------------------+ | id | l_uuid | l_username | l_domain | r_username | r_domain | realm | auth_username | auth_password | auth_ha1 | auth_proxy | expires | flags | reg_delay | contact_addr | socket | +----+---------+------------+-----------+----------------+-----------------+-------+----------------+------------------+----------+---------------------+---------+-------+-----------+--------------+------------------+ | 1 | 1234567 | pbx | 127.0.0.1 | login | ip.provider.ru | | login | password| | sip:...com | 120 | 0 | 0 | | 10.130.0.23:5060 | I see this two 401 replies [image: изображение.png] 1st REGISTER Via: SIP/2.0/UDP 1.1.1.1:5060 ;branch=z9hG4bK589d.8183f2e6000000000000000000000000.0 To: <sip:login@ip.provider.com> From: <sip:login@ip.provider.com CSeq: 10 REGISTER Call-ID: 6818f1b436befce1-21980(a)10.130.0.23 Max-Forwards: 70 Content-Length: 0 User-Agent: server Contact: <sip:1234567@1.1.1.1:5060> Expires: 120 1st 401 WWW-Authenticate: Digest algorithm=MD5,realm=".......org",nonce=" *56806a6f32c49a3afea043c2fa42381f*",domain="sip:......org",qop="auth", *stale=FALSE* 2nd REGISTER Authorization: Digest username="login", realm=".....", nonce=" *56806a6f32c49a3afea043c2fa42381f*", uri="sip:......com", qop=auth, nc=00000001, cnonce="357420659", response="6e300c9f7f4d81095f29b5408f8d5191", algorithm=MD5 2nd 401 WWW-Authenticate: Digest algorithm=MD5,realm=".....org",nonce=" *3b9586f6d31a76e509eb204d8a030415*",domain="sip:.....org",qop="auth", *stale=TRUE* I think kamailio need to sent 3nd REGISTER with a new nonce, because stale=true.

Can I intercept this REGISTER and 401 in kamailio.conf? Is there any examples? I know about this instruction https://kamailio.org/docs/modules/5.7.x/modules/uac.html :) Itried in request_route xlog("L_NOTICE", "uac 114411 1 remote fU $fU user [$rU] on [$rd] via [$du] $Ri \n"); if (uac_reg_request_to("$fU", 0)) { xlog("L_NOTICE", "uac 114411 Found remote user [$rU] on [$rd] via [$du]\n"); t_on_failure("REMOTE_AUTH"); #t_relay(); } And failure_route failure_route[REMOTE_AUTH] { if ($T_reply_code == 401 or $T_reply_code == 407) { xlog("L_NOTICE", "uac 114411 Remote asked for authentication\n"); uac_auth(); } } but I haven't got logs on register request, 401 reply. -- Best regards, Alex
