We have added two custom commands to be able to disable the update popup completely for the end users, and also to set the correct headset implementation from the installer.
Custom Options:
DISABLE_UPDATER=1 (or 0 which is default)
HEADSET=jabra (or plantronics, yealink)
The default commands within msi is also available (such as INSTALLDIR etc)
Example of how to install the Communicator with msiexec, completely silent, disabled update prompt and jabra implementation:
msiexec.exe /i 'Communicator-200.30.66.msi' DISABLE_UPDATER=1 HEADSET=jabra /q
