We are doing the evaluation with Cisco Jabber voice for iPhone 9.1.9, before iOS upgraded to 9.0, the Jabber Voice for iPhone works correctly. With latest iOS version, it can't works correctly, always shows with disconnection to CUCM server. Also I found I can't download the Cisco Jabber Voice from apple store in currently.
Does anyone have the same issue or what‘s happening with Cisco Jabber Voice?
We trying to register Iphone with iOS 9.0 and iOS8.6 on CUCM&CUP 11 but it is not working correctly
in 10% of connection trying everything is fine but in 90% when Jabber voice is trying to connect to CUCM it download 1 of 4 certificates and say that could not connect to server.
All android is working fine
Please advise what to do?
