[Kamailio-Users] lifetime and TCP connection timeout

Hi all, I'm working on improving my TCP support and go some issue related to TCP connections and lifetime/persistence. 1-> I'm able to have kamailio to keep opened the TCP connection by sending CRLFCRLF keepalive within my application: this solve the issue. 2-> With (or without) SO_KEEPALIVE option, kamailio discard/close the connection 50 seconds after my intial SIP message and 30 seconds after my last SIP message. My registration is using 500 seconds and I got default lifetime paratemer, which is 120 in the tcp_main.c code. My problem is that I'm supposed to send CRLFCRLF with a frequency advised between 95 seconds and 120 seconds (outbound draft keep alive). However, kamailio has already closed the connection and it only works for lower value. Did I made a mistake somewhere... -Note that for mobile device, the interval is supposed to be between 840 and 672 seconds.- Tks for your help, Aymeric MOIZARD / ANTISIP amsip - http://www.antisip.com osip2 - http://www.osip.org eXosip2 - http://savannah.nongnu.org/projects/exosip/
