The VMP Server sends wakeup notifications to clients that are offline or do not have a Vocera Voice Server ID, and that have not sent a getpushdata query to the server within the last 5 minutes and 15 seconds.
When the server sends a wakeup notification, it sends a VoIP notification to clients running version 3.2 or later of VCS on iOS or a FCM notification to clients running version 3.2 or later of VCS on Android. It sends a regular APNS or FCM message to clients running older versions of VCS.
If a VCS client is also a Vocera Voice Server user and is logged into the Vocera Voice Server, notification is handled by both the Vocera Client Gateway and the VMP Server.
