Hello Intermedia,
Without knowing the old and new Software Version it is hard to judge or guess what issue you have.
The current UCS 4.0.x Software has a bug that does not show received calls / missed calls in the received call list due a missing SIP header from the SIP switch.
In order to determine if you are having the same issue I can only suggest you raise a case with Polycom support via your Polycom reseller.
The only workaround is to downgrade to your known working software version.
Best Regards
Steffen Baier
