Greetings,

I'm doing a migration from a opensips system to kamailio one and i'm trying to replicate its functionalities.

The system is a Registrar with a pstn gateway. I noticed that on the opensips version, loose_route() is called on initial requests and it seems to be used to protect against preloaded routes.

However, on the default Kamailio configuration file loose_route() is only called on requests in-dialog and the verification mentioned above is not used.

Why doesn't Kamailio includes this verification? Is there are any security concerns not using it?
