Since the firewall was using two different ISP's, there were two different source IP's, causing hung connections that eventually choked the server to death.<div><br></div><div>Once our site had all of the SIP connections coming from one of the IP's, the problem resolved. Before we discovered the cause of the problem, our vendor had a cron job set to restart the SIP server every X number of minutes (I can't remember what the interval was, but it did help).</div><div><br></div><div>I hope this info helps you out.</div><div><br></div><div>Liz Rea</div><div>NEKLS</div><div><br><div><div>On Nov 6, 2009, at 8:19 AM, Melanie Hedgespeth wrote:</div><br class="Apple-interchange-newline"><blockquote type="cite"><span class="Apple-style-span" style="border-collapse: separate;
