How about next config snippet:

route[GET_NEXT_HOP]
{
    $var(next_hop) = $null;

    if (is_request()) {
        $var(next_hop) = $sel(next_hop.host);
    } else if (is_reply()) {
         if ($sel(via[2].received) != $null)
            $var(next_hop) = $sel(via[2].received);
        else
            $var(next_hop) = $sel(via[2].host);
    }
}

If you need to know what next hop kamailio will use to forward current sip message (request/reply) you can just call route(GET_NEXT_HOP) which puts what you need into $var(next_hop).

Dear list,

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
