If you are running some specific or proprietary Kamailio modules in your VoIP infrastructure and would like to harden them against attacks, please contact me. These additional tests can be easily done on my infrastructure.
If you would like to support me to make Kamailio more secure against malicious attacks, I am happy about sponsoring as well.
