[SR-Users] Reject tls invites without a=crypto sdp

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
