We recently learned from Apple that Cisco Jabber for iOS will continue to work as today when receiving notifications for IM and calls. The next major iOS release after iOS 11 will not break Jabber notifications for IM and calls for customers that have not yet upgraded their infrastructure to support Apple Push Notifications (APNs). As a result, customers have more time to execute the mandatory push notifications upgrades to the UC Infrastructure which will ensure that Jabber for iOS continues to work in the future.
Cisco recommends that customers update their Jabber infrastructure by June 2018 for best performance, or as soon as possible thereafter.
Upgrading will provide the following benefits:
Future proofing the infrastructure for Jabber for iOS: We do not know when Apple will remove the entitlements that allow Jabber to take advantage of legacy VoIP APIs / keepalives
Improved reliability and performance: APNs has the ability to wake Jabber even if Jabber has been terminated by iOS
Optimized and consistent user experience with cellular calls and other iOS applications
Reduced impact of Jabber on the device battery & potentially improved performance of other applications on the device
Multiline released in Jabber 12.0 requires CUCM 11.5(1) SU3 or higher
APNs upgrades are available now with the following minimum version requirements:
Recommend CUCM 11.5(1) SU4 – available since February 2018
OK if already running CUCM 11.5(1) SU3a – available since August 2017
CUCM to register and stay connected to Cisco Collaboration Cloud
