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
