Configure Push Notifications for Cisco Jabberon iPhone and iPad

• Push Notifications Overview, on page 1• Push Notifications Configuration, on page 3

Push Notifications OverviewWhen your cluster is enabled for Push Notifications, Cisco Unified Communications Manager and the IMand Presence Service use Apple’s cloud-based Push Notification service to push notifications for voice andvideo calls, instant messages, and Cisco WebEx invitations to Cisco Jabber for iPhone and iPad clients thatare running in suspendedmode. Push Notifications allows your system to maintain a persistent communicationwith Cisco Jabber. Push Notifications is required both for Cisco Jabber for iPhone and iPad clients that connectfromwithin the enterprise network, and for clients that register to an on-premise deployment via Expressway'sMobile and Remote Access (MRA) feature.

Push Notifications is required only for Cisco Jabber for iPhone and iPad clients. The feature is not supportedfor Android and is not applicable for Windows and Mac users.

Note

How Push Notifications Works

At startup, Cisco Jabber clients that are installed on iPhone and iPad devices register to Cisco UnifiedCommunications Manager, the IM and Presence Service and to the Apple cloud. With MRA deployments,the Cisco Jabber for iPhone or iPad client registers to the on-premises servers via Expressway. So long as theJabber client remains in foreground mode, Cisco Unified Communications Manager and the IM and PresenceService can send calls and instant messages to the Jabber client directly.

However, once the Cisco Jabber client moves to suspended mode (for example, to maintain battery life), thestandard communication channel is unavailable, preventing Cisco Unified Communications Manager and IMand Presence Service from communicating directly with the client. Push Notifications provides another channelto reach the Jabber client via the Cisco and Apple clouds.

Cisco Jabber is considered to be running in suspended mode if any of the following conditions are true:

• the Cisco Jabber application is running off-screen (i.e., in the background)

• the iPhone or iPad is locked

• the iPhone or iPad screen is turned off

Note

Figure 1: Push Notifications Architecture for Cisco Jabber for iPhone and iPad

The above diagram displays what happens when Cisco Jabber for iPhone and iPad clients run in the backgroundor are stopped. The figure illustrates: (1) an MRA deployment where the Cisco Jabber client that connectswith an on-premises Cisco Unified Communications Manager and IM and Presence Service deployment viaExpressway, and (2) a Cisco Jabber for iPhone or iPad client that connects directly to the on-premisesdeployment from within the enterprise network.

For a detailed description of what happens with each use case, see the following table:

Standard communication channels are used for voice, video, IM and Presence:

• For on-premises mobile clients, Cisco Unified CommunicationsManager and IMand Presence Service send the call or instant message to the Jabber client directly.

• For MRA clients, the call or IM notification is sent to the Jabber client viaExpressway.

For voice and video calls, the Push Notification is still sent via the PushNotification channel, but the Cisco Jabber client uses the standard channel.

Voice or Video Calls

Standard communication channels are unavailable. Cisco Unified CommunicationsManager uses the Push Notifications channel.

Upon receiving the notification, the Jabber client re-enters foreground modeautomatically, and the client rings.

Instant Messaging

Standard communication channels are unavailable. IM and Presence Service uses thePush Notifications channel to send IM notifications as follows:

1. IM and Presence Service sends the IM notification to the Push REST service inthe Cisco cloud, which forwards the notification to the Apple cloud.

2. The Apple cloud pushes the IM notification to the Jabber client and a notificationappears on the Jabber client.

3. When the user clicks the notification, the Jabber client moves back the foreground.The Jabber client resumes the session with the IM and Presence Service anddownloads the instant message.

While the Cisco Jabber client is in suspended mode, the user's Presencestatus displays as Away.
