Push Notifications OverviewWhen your cluster is enabled for Push Notifications, and the IM and Presence Service use Google and Apple’scloud-based PushNotification service to push notifications for voice and video calls, instant message notificationto Cisco Jabber or Cisco Webex Teams on Android and iOS clients that are running in suspended mode (alsoknown as background mode). Push Notifications allows your system to maintain a persistent communicationwith Cisco Jabber or Cisco Webex Teams. Push Notifications is required both for Cisco Jabber and CiscoWebex Teams on Android and iOS clients that connect from within the enterprise network, and for clientsthat register to an on-premise deployment through Expressway's Mobile and Remote Access (MRA) feature.
How Push Notifications Work
At startup, clients that are installed on Android and iOS platform devices register to , the IM and PresenceService and to the Google and Apple cloud. With MRA deployments, the clients registers to the on-premisesservers through Expressway. So as long as the Cisco Jabber and Cisco Webex Teams client remains inforeground mode, and the IM and Presence Service can send calls and instant messages to the clients directly.
However, once the Cisco Jabber or Cisco Webex Teams clients moves to suspended mode (for example, tomaintain battery life), the standard communication channel is unavailable, preventing and IM and PresenceService from communicating directly with the clients. Push Notifications provides another channel to reachthe clients through the partner clouds.
Cisco Jabber and Cisco Webex Teams is considered to be running in suspended mode if any of the followingconditions are true:
• the Cisco Jabber or Cisco Webex Teams application is running off-screen (in the background)
• the Android or iOS device is locked
• the Android or iOS device screen is turned off

Figure 1: Push Notifications Architecture
The above diagram displays what happens when Cisco Jabber or Cisco Webex Teams for Android and iOSclients run in the background or are stopped. The figure illustrates: (1) an MRA deployment where the clientsthat connects with an on-premises Cisco Unified Communications Manager and IM and Presence Servicedeployment through Expressway, and (2) a Cisco Jabber or Cisco Webex Teams for Android and iOS clientsthat connects directly to the on-premises deployment from within the enterprise network.
As of iOS13 for Apple clients and supported Android clients, voice calls and messages use separate PushNotifications channels ('VoIP' and 'Message') to reach a client that is running in background mode. However,the general flow is the same for both channels. With iOS 12, voice calls and messages are delivered using thesame channel.
Note
Push Notifications Behavior for Cisco Jabber and Cisco Webex Teams
The following table describes the behavior under iOS 12 and iOS 13 for Cisco Jabber or Cisco Webex TeamsiOS clients that are registered to and the IM and Presence Service.

The behaviour is the same as with iOS12.Voice and Video Calls
sends voice and video calls to Cisco Jabberor Cisco Webex Teams clients directly usingthe standard SIP communications channel.
For calls, also sends Push Notifications toCisco Jabber or Cisco Webex Teams clientsthat are in foreground mode. However, thestandard SIP channel gets used to establishthe call, rather than the Push Notificationschannel.
Messages
The IM and Presence Service sends messagesto the client directly using the standard SIPcommunication channel. For messages, PushNotifications are not sent to clients that arein foreground mode.

With iOS13, call traffic and message trafficis split into separate Push Notificationschannels: a 'VoIP' channel for calls, and a"Message" channel for messaging.
Voice or Video Calls
Standard communication channel isunavailable. Unified CM uses PushNotifications 'VoIP' channel.
Upon receiving the VoIP notification, Jabberlaunches CallKit with Caller ID.
This behavior holds for Cisco Jabber or CiscoWebex Teams iOS clients.
Messaging
Standard communication channel isunavailable. IM and Presence Service usesPush Notifications 'Message' channel.
1. IM and Presence Service sends the IMnotification to the Push REST service inthe Cisco cloud, which forwards thenotification to the Apple cloud.
2. The Apple cloud pushes the IMnotification to the Cisco Jabber or CiscoWebex Teams client.
3. When the user clicks the notification,Cisco Jabber or Cisco Webex Teamsclient moves to foreground mode. CiscoJabber or Cisco Webex Teams clientresumes the session with the IM andPresence Service and downloads themessage.
While Cisco Jabber or CiscoWebex Teams client is insuspendedmode, the user Presencedisplays as Away.
Note
Voice or Video Calls
Standard communication channel isunavailable. Unified CM uses the PushNotifications channel.
Upon receiving the notification, the CiscoJabber or CiscoWebex Teams client re-entersforegroundmode automatically, and the clientrings.
Messaging
Standard communication channel isunavailable. IM and Presence Service usesthe Push Notifications channel to send IMnotifications as follows:
1. IM and Presence Service sends the IMnotification to the Push REST service inthe Cisco cloud, which forwards thenotification to the Apple cloud.
2. The Apple cloud pushes the IMnotification to the Cisco Jabber or CiscoWebex Teams client and a notificationappears on the Cisco Jabber or CiscoWebex Teams client.
3. When the user clicks the notification, theCisco Jabber or Cisco Webex Teamsclient moves back the foreground. TheCisco Jabber or Cisco Webex Teamsclient resumes the session with the IMand Presence Service and downloads theinstant message.
While the Cisco Jabber or CiscoWebex Teams client is insuspended mode, the user'sPresence status displays as Away.
