After two days a response of a single question was replied too, we do not support Lion. And no elaboration or indication of when they will was mentioned. What a waste of money. Awful support response time and now a worthless app.
If you receive a phone call while using the app with VOIP the synchronization is completely messed up so the backgrounding does not work very well for that reason as well. So it only slightly works with voip calls.
