    <p>But this is different scenario than the logs you sent, so I can't
      relate them anymore.</p>
    <p>Maybe it is better to send both the pcap with all sip messages of
      the call and the logs taken for that call. First add in your
      config:</p>
    <p>log_prefix="{$mt $hdr(CSeq) $ci} "</p>
    <p>To be easier to correlate the logs with the sip messages as well
      as look at messages with wireshark of other tool.<br>

            <p>Hello,<br>
            </p>
            can you give here the INVITE that is sent out by Kamailio?
            In the screenshot that you gave in a previous email it was
            the incoming INVITE.<br>
            <br>
            From the logs, the 487 is matching the first branch, but
            that should be the one that was suspended, not the outgoing
            one.<br>
            <br>
            Reading back this email thread, you said:<br>
            <br>
            "I am resetting this flag 'T_ASYNC_SUSPENDED' before
            suspending the transaction."<br>
            <br>
            How do you do that? Can you list the order of operations
            that happen, like next?<br>
            <br>
               - INVITE received<br>
               - http async for auth<br>
               - reset the T_ASYNC_SUSPENDED flag ?!?<br>
               - http async for push<br>
