In alignment with Apple's changes to the iOS notification architecture, Cisco Jabber is in the process of implementing Apple Push Notification support for notifications. I highly recommend that customers upgrade Cisco Unified Communications Manager, IM and Presence Service, Cisco Expressway, and Cisco Jabber before June 2018. Failure to upgrade in a timely manner will result in loss of voice, video, and IM notifications for Jabber iOS users.
Upgrade Requirements to Support Push Notifications...
Enable Push Notifications
Use this procedure to set up the Push Notifications feature for Cisco Jabber for iPhone and iPad clients. This release provides Push Notifications support for voice calls and instant messaging with High Availability.
Before You Begin
Make sure of the following:
Port 443 must be open from the Cisco Unified Communications Manager publisher node for outbound HTTPS requests.
Both the Cisco Push Notification Service and the Cisco Management Agent Service network services must be running in Cisco Unified Serviceability. Both services are enabled by default.
Step 1: Log in to the Cisco Unified Communications Manager publisher node.
Step 2: From Cisco Unified CM Administration, choose Advanced Features > Cisco Cloud Onboarding. The page may take a minute to load while Cisco Unified Communications Manager checks whether the Cisco cloud is reachable, and whether certificates are present.
Step 3: Check the Enable Push Notifications check box.
Step 4: Check the I want Cisco to manage the Cisco Cloud Service CA Certificates required for this trust check box to have the system update certificates automatically.
Note: If you leave the check box unchecked, you will have to obtain CA certificates manually and copy them to Cisco Unified Communications Manager and IM and Presence Service. For details, see Certificates for Cloud Connection.
Step 5: If you want to use an HTTP or HTTPS Proxy to reach the Cisco cloud, check the Enable HTTP Proxy check box and enter the server details.
Step 6: Click Save.
Step 7: On the publisher node only, restart the Cisco Tomcat service to install Cisco-managed certificates.
Log in to the Command Line Interface.
Run the utils service restart Cisco Tomcat command. After the Cisco Tomcat service restarts, the Status in the Cisco Cloud Onboarding Configuration indicates "Cisco Cloud Onboarding Pending".
Step 8: In the Cisco Cloud Onboarding Configuration window, make sure that the Enable Push Notifications and I want Cisco to manage the Cisco Cloud Service CA Certificates required for this trust check boxes are still checked. You may need to recheck them.
Step 9: Optional. Configure troubleshooting settings to ensure that system issues can be resolved quickly. See the online help for field descriptions.
Check the Send Troubleshooting Information to the Cisco Cloud check box.
Check the Send encrypted PII to the Cisco Cloud for troubleshooting check box.
Step 10: Click Save The cluster initiates a Push Notifications subscription request. When the request completes, and Push Notifications is enabled, the Status field displays the message "Cloud Onboarding Completed".
Step 11: If your deployment includes the IM and Presence Service, restart the Cisco XCP Router service for all IM and Presence Service cluster nodes:
Click the Control Center - Network Services link that appears in the Status area of the Cisco Cloud Onboarding window. If no link appears, log in to the Cisco Unified Serviceability interface and select Tools > Control Center - Network Services.
From the Server drop-down list box, choose the IM and Presence database publisher node, and click Go.
Under IM and Presence Services, select the Cisco XCP Router service.
Repeat this step for all IM and Presence cluster nodes.
