The presence profiles are stored locally for each user on the client PC in the presenceprofiles.xml file. This is located under %appdata%\estos\ProCall 8.
A real administrative default, similar to the user actions, which cannot be changed by the user and is additionally offered, is not possible here.
A configuration can be made on a client and then the above file can be rolled out on the network for each user. However, this would overwrite locally already made adjustments. The changes are available there after a restart of the client.
