Well, you could simply use

if ( has_body("application/sdp") ) {
if ( !search_body("a=crypto") ) {
... reject here ...
}
}

though there's probably a better way...

Hi,

I use Kamailio 5.3.1 with rtpengine to offer an siptrunk endpoint for my customers.

I observe that someone of them use tls to encrypt signaling but forgotten to encrypt rtp.

I want to reject this invites.

Are there any hints how to do this?

Thought about reading the sdp and search for a=crypto line and if not send reply with (what code ever will be good for that).

Cheers
Karsten
