Kamailio for topology hiding and core SIP network protection

Kamailio is a high capacity SIP packet routing engine offering many functions for detecting and blocking malicious traffic targeting real time communication services. Along side, it can be used to hide the routing path, keeping sensitive details out of the sight of bad actors and untrusted peers, significantly increasing the security of RTC systems deployed on the cloud. This talk present the mechanisms offered by Kamailio to completely hide and protect your farm of SIP application systems (PBXes, PSTN gateways, audio/video conferencing systems or other media servers) deployed in your cloud core network.

There are a million reasons to attend ClueCon and we’re going to do our best to name them all! Reason number five is that we have four networking events, including Fun, Food, and Festivities by Flowroute and FreeSWITCH, all planned with developers in mind.

Specialized restaurants are a staple to Chicago tourism and we wouldn’t want you to miss out on anything that the Windy City has to offer! Join us for our second year of southern-comfort style food with a side of sass; this restaurant features an eccentric twist that will guarantee a lot of laughs. The servers at Last Resort are encouraged to lightheartedly antagonize its customers…but don’t worry! You’ll have your ClueCon family to back you up.
