CUPC Error - Failed to start conversation Start conversation capability is not available

Question

We are running CUCM 7.1.5.32900-2 and Presence 8.5.2.10000-49.
When some of the users highlight numbers and call them using click to call (The click to call that comes as a part of CUPC), they are getting the following error box...
Error
Failed to start conversation
Start conversation capability is not available
Our users typically have 7941 phones that are associated with their user. They are not using softphone.
Has anyone else come across this error, and what was the culprit?
Thanks,
David

Hi David,

Cannot Place or Receive Calls After a Secure Profile is Enabled
Problem   After a secure profile is enabled for a user, the user cannot place or receive calls. The user might see the following error message multiple times:
Failed to start conversation
The user can use the instant messaging features.
This problem occurs if a secure profile is enabled for the user in Cisco Unified Communications Manager while either of the following is true:
•The user is signed in to Cisco Unified Personal Communicator.
•The cucsf.exe process is running on the computer of the user, that is, Cisco Unified Personal Communicator is running, but the user has not signed in.
Ask the user to sign out of Cisco Unified Personal Communicator, then sign in again.
Hope it helps,
Anand
