[Users] How to reduce load of mediaproxy

[Alex]

Hello,

I'm sorry if this question was asked before, I googled and did not found
references to it.

I'm interested in reducing load of mediaproxy (using mediaproxy 1.8.0,
openser-devel).
Is it possible to connect callers not behind NAT directly and how configuration
should look like?

I want to direct traffic by this scheme:

Caller                Proxy              Called

NAT        <-   mediaproxy   -> NAT
NAT        <-   mediaproxy   -> not NAT
not NAT <-   mediaproxy   -> NAT
not NAT <- direct connect -> not NAT

I tried configuration something like this:

route {
if (client_nat_test(3)) {
use_media_proxy();
t_on_reply("1");
}
}

onreply_route[1] {
if (client_nat_test("2")) {
use_media_proxy();
}
}

And it works fine then caller is behind NAT and called is not (NAT <-> not NAT)
- traffic was directed via mediaproxy.
But, then caller is not behind NAT and called is (not NAT <-> NAT), this
configuration does not work.

Any suggestions? Thanks.
