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_From:]
[last_To:]

</send>
And I expect the Kamailio to send a retransmit, but it doesn't.

That sounds like the client does not receive the 407.

Hello,
UAC sends INVITE to UAS, authorization procedure is required, therefore
UAS
responds with an 407 error code. At this point, the client does not
respond with ACK, but the server does not send retransmits.
Is this the expected behavior?
* UAC -- SIPp, UAS -- Kamailio.
Can the Kamailio be configured to send 407 code retransmissions?
Thanks!
