How would checking $rP help?

Kamailio won’t process HTTP requests on a TCP SIP listener since they lack the SIP/2.0 request line signature.

It’ll process them through xhttp, though. Is that the context in which this is an issue? If so, just expose your xhttp resources via an obscure URL ($hu) and deny anything else.

I’ve set up a server listening on TCP recently, and notice that I’m receiving intermittent, random HTTP requests from the internet.  While it would probably be a good idea to enforce a firewall rule to only allow known hosts to communicate, what would be the best way within Kamailio to ignore http requests?  Would just checking $rP work?
