In Cisco CallManager 4.0(1), the user cannot connect to the Cisco IP Communicator. The Registration Rejected:Error Mismatch and DBconfig error message is displayed

Core Issue

The Cisco CallManager 4.0(1) documentation makes incorrect reference to the Cisco IP Communicator as a supported phone type for CallManager 4.0(1).

Cisco IP Communicator is not supported in this release of Cisco CallManager, and it     is currently supported by only 3.3(3) SR 3 and newer versions of the 3.3 CallManager. Ignore all references to Cisco IP Communicator in this documentation.

There is a Cisco bug written to address the confusion caused by the discrepancy    in the Cisco CallManager 4.0(1) document. The release notes of the CallManager 4.0(1) also indicates this discrepancy.

These are the excerpts from the release notes of the Cisco CallManager 4.0(1)    addressing the discrepancy:
