A user receives this error message when trying to start an ad hoc group chat with Cisco Unified
PresencE. “Attempted to perform an adhoc group chat operation but the AD_HOC_GROUP_CHAT
capability was not available.” What is the solution?

A.
Check if the conference server alias configuration is missing. If it is missing, add the configuration
and restart the Cisco Unified Personal Communicator.

B.
Upgrade the server to version 8.x because the Cisco Unified Personal Communicator client 8.0 is
not supported on the 7.0 platform.

C.
Remove the corrupted entries in the database.

D.
Ensure that the DNS server to which the PC is pointed can resolve the fully qualified name of the
Cisco Unified Presence Server.
