Hello,<div><br></div><div>Since last few days my freeswitch server receives SPAM calls. 25 to 30 calls at the same time. It makes my mod_managed program crash.</div><div><br></div><div>Unlike regular phone numbers in US, these seem to come from sip IP addresses. When I see location of these IP addresses, most of them seem to be from China.</div>
<div><br></div><div>Sample from CDR:</div><div><div> <caller_profile></div><div> <username>sip</username></div><div> <dialplan>XML</dialplan></div><div> <caller_id_name>sip</caller_id_name></div>

</div><div><br></div><div><div>I am only expecting call from regular phone lines from USA. I use Vitelity and I have secured my Vitelity configuration (SOFIA) with secret code provided by them.</div><div><br></div><div>How do I stop these anonymous SIP callers from crashing my system?</div>
<div><br></div><div>Please help.</div><div><br></div><div>Thank you.</div><div><br></div><div></div></div>
