<tt>Hi,<br>
<br>
It is hard to say without a pcap - try to make a call capturing on
the LB server, showing both in and out SIP packets.<br>
<br>
Regards,<br>

</div>
<div>In the opensips.log file, for some of the calls I see the
reply 200 logged 4 times. And whenever that happens, the same
is not sent back to the originator of the call.</div>
<div><br>
</div>
<div>At the end of the day some calls are ending up in ambiguous
result codes as they don't receive 200 OK. And all the calls
in this category, we see the reply 200 logged 4 times in the
log.</div>
<div><br>
</div>
<div>Any clue on what could be the issue?</div>
<div><br>
