System requirements

T.Mugen is installed on the same server where T.Lion was deployed. You must use T.Lion version 5.6.67 or later. Refer to upgrade instructions for details on updating from earlier versions.

In addition to standard T.Lion server requirements, you should:

  • Set up the public domain name on which T.Mugen web interface will be available to end-users (provide DNS parameters in the service request).
  • Provide signed SSL certificate for the public domain name. All certificate files should be placed in the /root/certs directory of T.Lion server or attached to the service request.
    Important: To ensure that all users can access T.Mugen without browser warnings, it is recommended to buy an SSL certificate from a trusted certificate authority (CA).
  • While it is possible to configure the custom port for T.Mugen web interface, we recommend using the standard HTTPS port (443). Make sure no third-party application (such as Apache) is using the port 443 on the server and that this port is opened on a firewall.
  • Allow inbound connections to the specific ports.


T.Mugen runs in a web browser and does not require any additional software to be installed. The following web browsers have been tested for compatibility:

  • Google Chrome version 93;
  • Microsoft Edge (Chromium) version 93;
  • Mozilla Firefox version 92;
  • Safari version 14.

To allow voice communication, the client device must have a sound card with playback and recording devices, such as speakers / headphones and a microphone.


Each user session in T.Mugen consumes TF.SMART licenses.
