By: snuffy (snuffy) 2018-02-02 00:00:50.181-0600 Hello Joshua, I have experienced the issue as well, there is another bug open for this (hidden) I believe they are looking into it By: George Joseph (gjoseph) 2018-02-02 08:32:44.185-0600 Check if res_pjsip_transport_management.so is loaded. By: George Joseph (gjoseph) 2018-02-02 09:06:45.310-0600 I'm marking this as a security issue  because I believe it's the same cause as the issue I just linked which is that if a tcp connection goes away while we're sending a response to an invite, we can see the crash.
