Try something NOT ubuntu. Ubuntu disables some required stuff in their openssl making it unusable for webrtc at least in some versions.

While waiting for suggestions, I tried more things. In particular, I tested whether gentls_cert was present in our FS install (which is at /opt/freeswitch/ on ubuntu).

It is present, but the CA root cert step writes to {prefix}/etc/freeswitch/tls/CA/ instead of {prefix}/conf/ssl/CA/. In particular, the root CA step generates:

etc/freeswitch/tls/ cafile.pem

etc/freeswitch/tls/CA/ cacert.pem cakey.pem config.tpl

And the server cert step generates:

etc/freeswitch/tls/ agent.pem

etc/freeswitch/tls/CA/ cacert.srl

Reviewing agent.pem shows it's fine: openssl x509 -noout -inform pem -text -in /opt/freeswitch/etc/freeswitch/tls/agent.pem

But it's owned by user root group root, so: cd /opt/freeswitch/etc/freeswitch/tls/ chmod 640 agent.pem CA/cacert.pem chown root.freeswitch agent.pem CA/cacert.pem

Then I edited /opt/freeswitch/etc/freeswitch/vars.xml to set internal_ssl_enable and external_ssl_enable to true.

Then I restarted FS. I checked the CLI and it shows "WS SETUP FAILED" repeatedly. *Any suggestion?*

Blazing ahead...then I exposed the public IP of the FS machine under a subdomain of the CA root cert's domain. (I used a wildcard subdomain for -org when generating both certs; maybe giving a wildcard this way is unnecessary or counterproductive.)

Now, the part that puzzles me: I'm already using a "real CA" cert in order to serve my verto client files over https from my DNS name, so browsers won't show security warnings. But I bet I need to have the same CA root cert installed in FS as I use in the webserver, right? I saw the note that commercial certs should work, but *it's not clear what steps to follow to install one*.

We would like to secure both signalling and media via TLS + SRTP, and I've read https://freeswitch.org/confluence/display/FREESWITCH/SIP+TLS <https://freeswitch.org/confluence/display/FREESWITCH/SIP+TLS> a few times to understand how to do this. Note that that page has a broken link: https://wiki.freeswitch.org/wiki/Secure_RTP <https://wiki.freeswitch.org/wiki/Secure_RTP>

First, is it still true that FS doesn't offer prebuilt installs (for Ubuntu) to support this kind of security?

Assuming that it must be compiled, I began to follow https://freeswitch.org/confluence/display/FREESWITCH/Debian+8+Jessie <https://freeswitch.org/confluence/display/FREESWITCH/Debian+8+Jessie> with the additional first step of: apt-get install libssl-dev

I soon ran into "Unable to locate package freeswitch-video-deps-most".

What should I try next?
