Hi List Digging further into my tcp/tls issues... Upon successful authentication I call: tcp_keepalive_enable("60", "5", "5"); tcp_set_connection_lifetime("120"); I tought, this would do to keep the connection alive. I noticed, despite keepalive packets being exchanged, kamailio is closing the connection after a bit more than 2 minutes. I am right at assuming, that tcp_set_connection_lifetime is not related to how long the connection is idle, but is counted from the SYN, no matter if keepalives were successfully exchanged? Does calling tcp_set_connection_lifetime() again restart the lifetime like for 2 more minutes like in this example? Or would I have to keep increase the value of the lifetime on each successful re-register to keep it open?
