TrueConf client applications can be launched via command line parameters. In this case, upon opening the application users automatically can:

  • Log in
  • Connect to the right server
  • Launch applications in the selected mode (full screen or minimized)
  • Call users or join video conferences
  • Launch another instance of application to control the second camera, e.g. to capture the second video source.

Parameter List

TrueConf client applications for macOS and Linux (and TrueConf Client 6.5.9 for Windows) can be launched via command line parameters only when they’re entered with “/” (e.g. “/c george”).

Additionally, in TrueConf applications for macOS and Linux, if you specify parameters with a “\” character, you need to escape it with a second “\” character, e.g., “/c \\c\\6427906610”.

Function Parameter and Use Case
Login -l [user] -p [password] -e

-l maria -p 4839 -e

Server connection -h [server]:[port]


Launch Applications in Different Modes
Full screen (without interface elements) -f

This parameter is to be used in conjunction with -c parameter when automatically receiving and making video calls. It is also important to use this parameter if  you need to see users’ images without interface elements during video conferences.
Minimized -m
“Instance” mode -t [id]

By using this parameter, you’ll launch the instance of your application with ID specified by the user. Instance settings are saved separately from original settings. Once closed, these settings are saved and automatically brought back when restarted by using the same ID.
Call Users and Join Conferences
Call users -c [user]

-c george

-c [user] @ [server_name]


Join conferences on the server via \c\CID -c \с\[CID]

-c \c\6427906610

-c \с\[CID]@ [server_name]

-c \c\

Automatically close the application once the call/conference is ended -ac

This parameter can only be used in conjunction with -c parameter.

-c kate -ac

-c \c\5427905512 -ac


  • [user] — user login
