If indeed you mean ALL traffic, including traffic that Kamailio itself can
route internally:
Add something to the LOCATION route to only allow usrloc based routing from the
media server. In my case, I have added this at the top:
# Only do this for things authorized by IP
# UAs need to go via billing platform
if (!allow_source_address()) {
return;
}
Create a new route that is called at the end of your main route with something
like the following:
# Routing to Billing
route[BILLING] {
# only local users allowed to call
if (from_uri!=myself) {
sl_send_reply("403", "Not Allowed");
exit;
}
$ru = "sip:" + $rU + "@1.2.3.4:5060");
route(RELAY);
exit;
}
In essence, block all but allowed IPs (your media gateway IPs should be
allowed) from routing via usrloc and change the request URI to route all
traffic via the media gateway IP (1.2.3.4).

Subject: [SR-Users] Kamailio/How to send all requests ?
Hello !
I'm using Kamailio for 2 months, and I have a problem with the routing logic.
My aim is to use 2 Kamailio servers (in a cluster, so I have a primary and a
backup server with a Virtual IP that can switch between the 2 servers) working
with 2 medias servers (same as above, a primary and a backup). The Kamailio
servers are here to handle failover, so all the requests go through them, and
then are sent to the active media server.
My question is : Which module(s) should I load to transmit all the requests
(including registers) to my media server, through the Kamailio server ? Any
particular parameters ? Then, what will be in the "request_route" ?
I'm using Kamailio 4.3.4.
Best regards,
Alexandre
