When deploying Ringotel app, you may want to prefill the organization's domain for your users. This can be easily achieved by specifying an additional parameter "DOMAIN" during the installation process. This will save your users the hassle of having to enter their domain every time they log into the app.
For example, use this command when deploying via the command line (from the folder where a ringotel.msi file is located):
msiexec /i ringotel.msi domain=ringotel
You can also populate username and password as well:
msiexec /i ringotel.msi domain=ringotel;username=123;password=123
