I think in openser there is a function to check what transport the
message came in ... you can do something like:
if ( transport != TLS ) {
send error to UA
break;
}

Hello,
I use OpenSER in a testing environment for VoIP security. My clients connect
via TLS. If I deactivate UDP/5060 on the server, it doesn't work correct.
Some Clients can't connect and others can't establish calls. I read in
another thread, that UDP is mandatory for SIP and that the server need it.
But how can I prevent users from connecting via UDP and force them to use
TLS? I tried a firewall, blocking UDP and TCP on port 5060. But is this the
correct way? Are there any parameters server-side to force users to connect
via TLS?
Thanks for response.
Torsten
