Unfortunately there is no available Server Websocket library supporting SSL out of the box. To allow Websocket connections over SSL, it is needed to configure a reverse proxy in Apache.

Unfortunately Apache shipped with CentOS 6 doesn't not support proxying Websocket protocol, so ad additional package needs to be installed. The package can be installed from the server repository: 

yum -y install https://demo.mirtapbx.com/mirtapbx_support/mod_proxy_wstunnel-0.1-1.el6.fws.x86_64.rpm

Once this module is installed, you need to configure your reverse proxy by adding: 

<IfModule mod_proxy.c>
    ProxyPass "/wsrtportal/" "ws://127.0.0.1:8081/"
    ProxyPassReverse "/wsrtportal/" "ws://127.0.0.1:8081/"
</IfModule>

If you prefer, you can just copy the wsproxy.conf file from MiRTA PBX protected folder in /etc/httpd/conf.d and restart your web server.

The port needs to match the port specified in the Admin/Settings "Real Time Portal service - Listening Port"
