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.
