  • New ChatApp is active by default in ProCall client for Windows.
  • No more CustomTab is needed to include the ChatApp in the ProCall client for Windows.

Error analysis – debug logs

If unexpected display problems or incorrect displays occur in the chat app, proceed as follows:

  • Check the display after restarting the ProCall Enterprise client.
  • In case the restart does not solve the problem, back up the %localappdata%\estos\procall 8\EBWebView directory after ProCall Enterprise Client has been terminated.
    To do this, cut out the EBWebView folder, place it temporarily elsewhere and restart the ProCall Enterprise client.
  • If the problem is still not solved, please check the current version of the ProCall Enterprise client and update the ProCall Enterprise system to the latest version.
  • If the display problem persists, consider the instructions in the following tip:

Since the chat app in the ProCall client main window is based on web technologies, not all operations are logged in ProCall client debug logs (C:\Users\<username>\AppData\Local\estos\ProCall 8\logs). For certain observations, such as "There is no connection to the server...", outputs from the web development tools (DevTools) integrated in the browser used are therefore also necessary, which must also be made available for an error analysis:
