RE: 2 Openser Instances

I tried the cacheless mode, it didn't work for me.

I'm just wondering , how did those people out there do their OUTBOUND
proxy ?
Can anyone give me some hint ?

Regards,
Sam

http://openser.org/docs/modules/devel/usrloc.html#AEN252

it's mode 3 (only available in CVS head)

I still would use only one proxy and apply NAT traversal only for
clients which use the "NAT traversal" port on your openser.

The idea is:
...
if ( dst_port = 6060) { # needs NAT traversal
        if (is_method("REGISTER")) {
                setflag(9);
                # this is the natflag specified in userloc module #
http://openser.org/docs/modules/1.0.x/registrar.html#AEN103
                fix_nated_register();
        } else {
                # do all the NAT traversal, activate RTP proxy
        }
}

# now do the normal call and REGISTER handling

...





...
        lookup("location");
        if(isflagset(9)) {
           ...#force rtp proxy
        }
....
