SPCE protects against (whichever type it was DDOS or DOS), by giving a 403 forbidden. After this asterisk stops registering.</span></p>

It will also show up on your asterisk log and it will show in the spce lb/proxy logs (just before its stops trying, you’ll see spce giving a log entry about banning for a while).</span></p>

</p><div><p class="MsoNormal">Hello,</p><div><p class="MsoNormal"> </p></div><div><p class="MsoNormal">I have a few clients using Asterisk (Elastix, FreePBX) pbx. All is working well except sometimes after a few days or weeks the Asterisk stops registering. Unfortunately I do not have a log right now, but its so common that I started using a cron job to just reload the SIP stack on the Asterisk servers.</p>
