Its just a little thing to ask but I somehow can't seem to figure out which psuedo variable to use to find out where a particular 200 OK is destined to go. 

the scenario is I've multiple media servers in dispatcher and calls are distributed. I need to capture a 200OK that is destined to go to a particular ip!

I've tried using the dst_ip, $dd, $du but none of them are giving any results for the 200 OK. I just need to know where do kamailio is going to send this 200 since it is already a part of an on-going INVITE/call.

Thanks,

Sammy
