Jabber Push Notification delay causing voice call to drop before push notification reaches the iPhone. It appears that we are hitting this issue below
“If there is a delay in the Push Notifications process that prevents Unified CM from offering the call to the IOS device, Unified CM drops the call after 13 seconds.”
This is an intermittent issue where, in most cases, the iPhone mobile jabber begins to ring just as the Unified CM system is dropping the calIs there a way to increase the timer to accommodate the Push Notification delay or are there any recommendations?
On Both successful and failed calls, we received RESPONSE_PUSH_NOTIFICATION with Status 200 from Cisco Cloud for REQUEST_PUSH_NOTIFICATION without delay.
