Notice that the "Business hours" boolean has no GUID defined for it, and it's reason is undefined. After some experiments, it seems this is caused because the object was removed from the pbx using the old admin interface (PBX/Objects and then delete teh object). If you do this, the "Timeswitch" still exists apparently in the Pbx Manager/Time switches app of the app platform.

Is this expected behaviour? It seems that all data is thus not in the PBX Object, else you couldn't display this timeswitch and the app platform has additional data. But it cannot work because there is no underlying object. You can also not "delete" the object later on with the API, because there is not GUID to execute the delete command, so the app or api or old pbx interface can also not delete it. The only way to fix this is to go to the PBX manager and do a change in the time switch, which does an update without a GUID and then by default creates a new object with in the PBX as well with the settings, and then the time switch works again...
