The Cisco IP Phone places those menuItems ontop of the directories-url menu. The only thing you could try is to enter a invalid url as directory-url. The phone will then display a 404 error and probably won't show the missed calls etc.
The Init URI allows an application to initialize a feature or data with the argument that is passed with the URI.
o = the Object name.
Valid object name:
CallHistory-When the phone encounters an Init:CallHistory URI, it clears the internal call history logs that are stored in the phone. This action initializes Missed Calls, Received Calls, and Placed Calls.
Services-When the phone encounters an Init:Services URI, it closes the Services application. If Services is not currently open, it has no effect.
Messages-When the phone encounters an Init:Messages URI, it closes the Messages application. If Messages is not currently open, it has no effect.
Directories-When the phone encounters an Init:Directories URI, it closes the Directories application. If Directories is not currently open, it has no effect.
So you could create a scriptpage that will send an "Init:CallHistory" when pushing the directories button.
