Client/peer only TLS? Can it do it?

Everything I read shows that you have to set up and enable the SERVER side for TLS. I don’t want that.

I just need to have Asterisk call out using TLS, so I put:

transport=tls

In the client/peer info section n sip.conf with the other stuff like password and username etc…

Everything works fine normally via UDP and I can use tcpdump to observe if the packets are encrypted or not etc… And also it says that TLS will go out to port 5061 which I don’t see. I restart everything of course.

Everything is still going UDP, nothing special is going on.

The other end supports TLS, but that doesn’t matter right now, Asterisk isn’t even trying to go TLS.

Why can’t I do this?

edit: Forgot to say this is Asterisk 1.8.14.0-rc1
