This function calls (launches) a given command, i.e. launches any given application. It offers to write the output of the command (StdOut and StdErr) into the server trace file for later analysis.
Please see the Introduction chapter for some usage instructions.

Please note that this command will be launched on the SwyxServer machine. No windows will be opened, and no user input can be made. So only start command line applications which do not require any user input.
As the call routing is executed by the Swyx Server service, the command will also be executed by the Swyx Server service. That means, it is executed by the Windows user, the Swyx Server service is running under (usually this is the local SwyxServiceAccount user).
To call any standard command like "copy" or "move" you need to call the command line interpreter (cmd.exe) and then pass your command as parameter to it. The environment variable %comspec% provides to full path to cmd.exe.
This example copies all files from FolderA to Folder B.
LaunchCmdEx "%comspec% /c copy C:\FolderA\*.* C:\FolderB", True, True
Make sure that the SwyxServiceAccount (or the account you have configured to the Swyx Server service) has enough privileges to execute your command.
This function makes use of the Server Script API function PBXScript.OutputTrace to write trace information into the SwyxServer trace file.
