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/" retry=0 timeout=5
    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"

Updating libraries

It can be needed to upgrade some libraries used by the software, in this case you need to first install composer 

php -r "copy('https://getcomposer.org/installer', 'composer-setup.php');"
php -r "if (hash_file('SHA384', 'composer-setup.php') === '544e09ee996cdf60ece3804abc52599c22b1f40f4323403c44d44fdfdd586475ca9813a858088ffbc1f233e9b180f061') { echo 'Installer verified'; } else { echo 'Installer corrupt'; unlink('composer-setup.php'); } echo PHP_EOL;"
php composer-setup.php
php -r "unlink('composer-setup.php');"

then run composer update
