[SR-Users] logging sip messages

Hello: I am trying to find a simple way to log each and every SIP message that Kamailio receives or Kamailio sends. In a nutshell, here is what i'm trying to accomplish: - log sip message received; log ip address and port of where message was received from - log sip message to be sent or sent; log ip address and port of destination. I am trying to achieve this in the context of my general log file that contains routing/event logic from the kamailio.cfg file. By this i mean i don't want to have to run an external program like tcpdump to capture the packets and log them. I have tried a few thing but haven't been able to capture all conditions. examples: i have included things like event_routes for [tm:local-response]; [sl:local-response]; [sl:filtered-ack], onreply_route... I can capture most replies and responses via those but am not able to capture a 200ok relayed response from Kamailio back to the originating UA for example. I can log incoming messages without problem. I have also tried to activate IO interrupt to route to event_route[NETWORK:MSG] but unfortunately i can't access the source/dest ip address/port info or other pseudo variables. So back to the original question: How does one log every SIP message that Kamailio gets? How does one log every SIP message that Kamailio sends? via the context of the routing/replies/event routes in kamailio.cfg. Thanks, Karthik
