<div><br>
</div>
<div>since you are plain sip without encryption you can see your
sip-traffic on the wire,</div>
<div>use sngrep on the kamailio box to figure out whats with the
sip-dialogs - it helps a lot.<br>

<div>and if its more an kamailio config problem, it would be
better to stay at sr-users@.<br>
</div>
<div><br>
</div>
<div>Or you can setup an webhomer for debugging.</div>

<div dir="ltr">Once a call is answered FreeSWITCH sends a
200 OK SIP message to your Kamailio loadbalancer. As per
the SIP spec your kamailio box should respond to a 200
OK with an ACK. The FS logs show that it never receives
an ACK, and it repeatedly tries sending the 200 OK with
no response. After 30 seconds without an ACK FS will
assume the call has failed and hangup.<br>
<br>
Looking at your Kamailio SIP logs you can see the 200
OKs getting through okay, and no attempt to send an ACK
back to FS. I think this indicates an issue with your
kamailio.cfg rather than FreeSWITCH.<br>
