Purpose of this Document
This document describes how to configure Push Notifications on Cisco Unified Communications Manager and the IM and Presence Service for compatible Cisco Jabber and Cisco Webex clients that run on iOS or Android devices. With Push Notifications, your deployment uses Google or Apple's cloud-based Push Notification service to push voice call, video call, and instant message notifications to Cisco Jabber and Cisco Webex for iOS and Android clients that are running in the background. You must enable Push Notifications to maintain persistent communication with clients that are running in the backgound.
This document describes how to enable Push Notifications for the following deployment types:
On-Premise Deployments of Cisco Unified Communications Manager and the IM and Presence Service—For on-premises deployments of Cisco Unified Communications Manager and the IM and Presence Service, refer to Chapter 2 for instructions on how to enable the cluster for Push Notifications. This includes deployments where the clients register via Expressway's Mobile and Remote Access (MRA) feature.
Cloud Deployments with Webex Messenger—For cloud deployments with Webex Messenger, refer to Chapter 3 for deployment requirements.
The Webex Messenger cloud retires end of 2020. For more information, see https://blogs.cisco.com/collaboration/making-the-move-to-modern-messaging.
