We want to use Kamailio as the pass-thru proxy in

receive the request on a random port, and then forward the request to the
SBC internally being on the same private network.
What would be the best way to do it?
If it is the best is up to the experts, but a way to do is to check wheter the
source is the SBC or not. If the message is from the SBC just handle it
statefully (t_relay), if it isn't from the SBC set the requested domain to the
ipaddr of the SBC (10.1.2.3) and process stateful. You could use the received
port instead if external clients only communicate on the special port
($Rp!=6334)
kamailio.cfg:
#...
port=5060
port=6334
#...
request_route {
#...
if($si!="10.1.2.3")
{
$rd="10.1.2.3";
}
route(RELAY);
}
