I have also seen this with Kamailio 1.5 I have not confirmed whether Kamailio is sending the 200 OK back down to my asterisk server or not.<br><br><div class="gmail_quote">On Tue, Jun 29, 2010 at 7:15 AM, Klaus Darilion <span dir="ltr">&lt;<a href="mailto:klaus.mailinglists@pernau.at">klaus.mailinglists@pernau.at</a>&gt;</span> wrote:<br>

If you want to know from us if your config is wrong or your clients/server is buggy, then we need an ngrep dump recorded at the SIP proxy:<br>
<br>
ngrep -Wbyline -t -q port 5060<br>
<br>

Hello,<br>
<br>
See transmission below. For some reason the ACK package is lost/dropped and the remote server retransmits the 200 OK status. But Kamailio does not retransmit the ACK on receiving the retransmitted OK&#39;s. Eventually the remote server gives up and pulls the plug after ~20 seconds. Is this a bug or should I look closer at my routing script? The script is for the ACK handling pretty much the same at the vanilla script delivered with the source. I&#39;m still on version 3.0.0.<br>
