I have integrated Cisco Unified Presence 7.0 with CUCM 7.0 and successfully have all aspects of CUPC working.
On CUPS I have enabled the IP Phone Messenger service, and configured the appropriate Application userid and password.
On CUCM I have created the appropriate Application UserID, associated Handsets and made part of the Enable CTI Control of All Devices group.
I have also created a phone service with the URL http://<CUPS-IP-ADDRESS-HERE>:8081/ippm/default?name=#DEVICENAME#
and subscribed the relevant phones to this service.
Users are associated with both the Phone Device and the Line Appearance, and Primary Extension is configured in the user profile.
I am able to login using the PIN of the users successfully, however when I try and access the Contacts menu, I get "Requesting...." which attempts to load indefinitely. Eventually the request times out - but no error messages.
I manually added contacts via the Web User Options page, and confirmed that CUPC is working fine for these exact same users.
Has anyone experienced this behaviour before?
