The push notification mechanism enables clients to receive incoming call alerts and other notifications from the Apple Push Notification service (APNs). Configuring push notifications on the Avaya Aura® Web Gateway administration portal is part of the push notification configuration procedure. Before configuring push notifications on the Avaya Aura® Web Gateway administration portal, you must create and configure an Avaya Spaces account. You also need to configure settings on Avaya Aura® Session Manager and Avaya Aura® Communication Manager. For more information about the entire configuration procedure, see the sections under Avaya push notification management.
