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_stateless_reply Cheers, Henning -- Henning Westerholt – https://skalatan.de/blog/ Kamailio services – https://gilawa.com<https://gilawa.com/> From: sr-users <[email protected]> On Behalf Of Marat Gareev Sent: Sunday, February 7, 2021 10:02 PM To: Kamailio (SER) - Users Mailing List <[email protected]> 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 <[email protected]<mailto:[email protected]>>: That sounds like the client does not receive the 407. — Sent from mobile, with due apologies for brevity and errors. > On Feb 7, 2021, at 11:12 AM, Marat Gareev > <[email protected]<mailto:[email protected]>> wrote: > > > Hello, > > UAC sends INVITE to UAS, authorization procedure is required, therefore UAS > responds with an 407 error code.
