Also intressting to see how they solved this problems.
If you could describe your siptrunk a bit more,
then would here many people that can point you in the right direction how
to solve that with or without kamailio.

Thanks,
I want to eventually get to a setup like the one here:
https://github.com/CyCoreSystems/asterisk-k8s-demo
But since I'll need Kamailio to handle a high load of incoming calls, I
think I need it to direct traffic, etc for any number of Asterisk
servers behind it.
In this setup it indeed has RTPProxy, etc. I just want to understand how
to use it rather than just drop it in, etc. Also the demo doesn't have
any config for an outside SIP trunk, etc.
Maybe this helps?
Thanks,
Travis

The real question is what do you need
kamailio to do? You answer this
with as a simple proxy.
A possible solution for you is to use kamilio with the dispatcher
module. One
id (1) for the PSTN side, one id (2) for the
Asterisk side. If a call
comes in
from 1, route it to 2 and v.v.
This makes the kamailio machine the "endpoint" for both PSTN and
Asterisk side.
With the "default" config that comes with kamailio all you need to do is
strip out anything from the accounting bit in request_route (line 508)
https://github.com/kamailio/kamailio/blob/master/etc/kamailio.cfg
and insert something like:
if(ds_is_from_list("1",3))
{
$avp(dispatcherid)="2";
}
else if(ds_is_from_list("2",3))
{
$avp(dispatcherid)="1";
}
else
{
send_reply("403", "Go away");
exit;
}
route(DISPATCHER);
route(RELAY);
With route DISPATCHER being:
route[DISPATCHER]
{
if(!ds_select_dst($avp(dispatcherid), "4"))
{
send_reply("501", "No dispatcher available");
exit;
}
t_on_failure("RTF_DISPATCH");
return;
}
See
https://kamailio.org/docs/modules/stable/modules/dispatcher.html#dispatcher…
for more info on integrating the dispatcher
module.
More advanced subjects to look at are:
-do you need an rtp proxy?
-do you need topology hiding?
-is NAT involved?
But leave them until you have a clue about how to use kamailio as a sip
proxy in
a
simple test environment (e.g. between 2 asterisk
servers).
