Well you're using FreePBX right? The only corse of action you have is to find out why its crashing and reporting the issue on our Jira. Without any more info to go on you're SOL.

Hello,
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.
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.
Sample from CDR:
<caller_profile>
<username>sip</username>
<dialplan>XML</dialplan>
<caller_id_name>sip</caller_id_name>
<ani></ani>
<aniii></aniii>
<caller_id_number>sip</caller_id_number>
<network_addr>113.105.152.220</network_addr>
<rdnis>1442073479999</rdnis>
<destination_number>1056</destination_number>
<uuid>bef84579-d25a-ab4b-aa52-dbcf9d7509be</uuid>
<source>mod_sofia</source>
<context>default</context>
<chan_name>sofia/sipinterface_1/sip@113.105.152.220</chan_name>
</caller_profile>
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.
How do I stop these anonymous SIP callers from crashing my system?
Please help.
Thank you.
