Re: [SR-Users] Retransmission of 407

Hello, do you actually create a transaction before sending the 407, or using t_reply() to do it statefully? Check also if you not deactivated it on the module level, e.g. https://www.kamailio.org/docs/modules/5.2.x/modules/auth.html#auth.p.force_… Cheers, Henning -- Henning Westerholt – https://skalatan.de/blog/ Kamailio services – https://gilawa.com<https://gilawa.com/> From: sr-users &lt;sr-users-bounces(a)lists.kamailio.org&gt; On Behalf Of Marat Gareev Sent: Sunday, February 7, 2021 10:02 PM To: Kamailio (SER) - Users Mailing List &lt;sr-users(a)lists.kamailio.org&gt; Subject: Re: [SR-Users] Retransmission of 407 Isn't this the reason for sending retransmits? First of all I checked the successful case (attached screenshot). Then I replaced sending ACK with <timewait milliseconds="4000"/> so that the UAS has time to send retransmits before the connection drops. In this part of scenario: <recv response="100" optional="true"/> <recv response="180" optional="true"/> <recv response="183" optional="true"/> <recv response="200" rrs="true" optional="true" next="200ok"/> <recv response="407" auth="true"/> <send> <![CDATA[ ACK sip:[service]@[remote_ip]:[remote_port] SIP/2.0 [last_Via:] [last_From:] [last_To:] [last_Call-ID:] [last_CSeq] Max-Forwards: 70 Content-Length: [len] ]]> </send> And I expect the Kamailio to send a retransmit, but it doesn't. вс, 7 февр. 2021 г. в 19:31, Alex Balashov <abalashov@evaristesys.com<mailto:abalashov@evaristesys.com>>: That sounds like the client does not receive the 407. — Sent from mobile, with due apologies for brevity and errors. _______________________________________________ Kamailio (SER) - Users Mailing List sr-users@lists.kamailio.org<mailto:sr-users@lists.kamailio.org> https://lists.kamailio.org/cgi-bin/mailman/listinfo/sr-users
