IP addresses for sip traffic.<br>
<br>
The other listing port which is used by keepalived check script for bing-pong keeps responding to option messages.
<br>
<br>
Its very random behaviour occurs after a few days or after a few months, the system having max load 350 concurrent calls with load average 200-300. <br clear="all">
