Core Issue
When the user tries to delete the Cisco CallManager server from the CallManager cluster 3.1(4b), they receive this error message: This server cannot be deleted. 1 devices are using it.
In spite of removing the Cisco CallManager groups from the CallManagers list, as well as all the services and service parameters associated with the server, the error message cannot be deleted.
