Sniffing tools use kernel hooks before the firewall or other system limits (e.g., imposed
by selinux, conntrack, ...), so you can see the traffic on the network but it doesn't
get to the application. You have to review those settings.
Because Kamailio is sending the keepalive, this is clearly not a bug in Kamailio code. If
you need to discuss further to troubleshoot, then use the mailing list
sr-users(a)lists.kamailio.org. This issue tracker is for bugs in Kamailio code and send
notifications to sr-dev, which is not the appropriate place to discuss how to use
kamailio.
